Brake pad noises and wear out explained

Brake noise is a common part of brake operation. A majority of the time you will hear nothing inside your vehicle. Worn brake pads can make noises you would hear inside your vehicle. The most common noises are a crunch or runch sound. Another noise you may hear is a high pitch shriek. Shriek noises are very common with very worn brake pads or budget “cheep quality” brake pads, even if newly installed.

I like to install OE dealer brake parts when ever possible. OE parts fit correctly and offer the best noise control for the life of the brake pads.

When grinding noises happen every time you press the brake peddle. Your brakes are 100% worn out. the metal part of the brake pad is making contact with the metal brake rotor.

The service “wear out” specs on brake pad thickness can vary from 1mm to 2mm. Brake wear sensors will normally turn on the dash brake wear light around 2mm.

Brake pads that use a noise tab built into the pad, may make a high pitch noise only when backing up, but quiet going forward.

When I inspect brakes for wear, I look at the thinest brake pad to judge the wear % remaining. Once below 30% remaining life (around 3mm of pad thickness remaining) brake replacement will be needed soon.

If you are noticing brake noises, stop in at your local repair shop and have them inspect your cars brakes. Waiting to see if the noise just goes away can cause bigger issues.  If the brake rotors or brake calipers become damaged from metal to metal contact it can increase the cost of your brake repairs.

Need an oil change today?

We use a “synthetic blend” as our standard oil. Servicing you car is the most common reason to visit a repair garage. We use a synthetic blend because it extends the oil life, offering better protection against wear and resists carbon coking. If your car needs full synthetic we stock that too.

Regular motor oil: Regular oil works great for older engines, but if you do not service it regularly and or ignore your service intervals. It can lead to heavy carbon build up “hard sludge” or coking of the internal engine parts. “Coking aka soft sludge” “Coking” is characteristic of a high temperature reactions involving hydrocarbons. On todays small high revving engines, carbon deposits may cause restricted oil flow, shortening the life span of your engine.

Full Synthetic motor oil:  Synthetic oils primary use is in high heat stress applications like Arizona. Jet engines use Synthetic oil. Synthetic oils are great for cold climates too, it will flow normally even in freezing temperatures.  European cars, motor cycles and many of todays small turbo charged engines need full synthetic oils to prevent sludge and carbon build up.

Just stop in and let us know how we can help.

Tune-up

What is a Tune-up for a modern engine?

Carbon tracking on a 112,000 mile spark plug

From the mid 2000’s and up, the term Tune-up has been replaced with preventative maintenance. Newer engines don’t have anything to adjust. Everything is pre-set from the factory and you only replace parts if they fail or if you like to follow your maintenance schedule listed in the owner’s manual.

Converter meltdown due to a miss fire condition.

A modern engine can be adjusted through software changes, electronic tuning. Software tuning is not a normal undertaking and it voids the manufactures warranty. Programmers and software changes can build big power. All that power comes at a cost, more wear to the engine. When an engine replacement costs around 6,000.00 when it fails. What did you gain? You may also not pass emissions when it’s time for tags.

PCV hose failure.

You can make changes by putting aftermarket performance parts on the engine. Many parts you can bolt on will not void a warranty in most cases. Some bolt on parts can shorten engine life and cause emissions issues.

Replacing the exhaust system can have a big effect in power output. Exhaust changes effect how loud the tail pipe sounds. A loud exhaust is not needed to build power. The exhaust only needs to flow efficiently. Too much flow “big pipe exhaust systems” can hurt low rpm torque making your engine sluggish at lower speeds “city driving” and with the a/c on.

The days of the real tune-ups, when engines had a real distributer, plug wires and a carburetor. It was a common to have 2 or 3 tune-ups a day back in the 80’s and 90’s. The carburetor needed adjustments at lease every time the season would change or around emissions time. The distributer had mechanical parts in it that would wear out. Hoses failed, air pumps died, catalytic converters would melt down. Yep, the good old days, nothing lasted for ever.

Modern cars have owners spoiled. driving a car a 100,000 miles or 10 years and never-changing the spark plugs, coils or installing a new fuel filter is amazing. Modern engines are built better and run cleaner. The improvements do have a price.

Ignition wire failure because it made contact with the hot exhaust manifold.

When parts fail, the price to fix the failure can be very large. When sticker shock sets in, many clients ask why is it so expensive.

I can only tell them that in the good old days it cost the same, it was just done in smaller installments over a 10 year period.

2001 Chrysler Sebring LX No Start

Sebring; No Crank and No Check Engine Light:

The #8 fuse supports many devices. The starter, fuel pump, body control, engine control, ignition switch and 10 more devices. Knowing the product, I first look at the fuel pump, starter motor and starter solenoid. A bad starter solenoid or a faulty starter motor will cause a large amp load on the #8 fuse via the starter relay. The #8 fuse is only a 20 amp fuse. The starter and fuel pump relays are the highest loads placed on the #8 fuse.

The starter relay will normally draw 11 amps under normal conditions. When the starter relay first engages the amp spike can reach 22 amps, after the initial spike. It will take about 11 amps to hold the starter solenoid on. The amp spike is normal and the 20 amp fuse can handle a quick amp spike, just not a sustained load of 22 amps or more. If the starter solenoid is faulty, it causes more amps to flow through the relay. It’s a domino effect, One fault, will cause a failure in a secondary component.

Looking at how power flows through the circuits will shorten the time it takes to find out what device caused the fuse to fail. I start with devices that draw high amps.

The fuel pump relay will normally draw 2.5 to 3.8 amps under normal operation. When the pump first spins up. The amp spike is around 8 amps, then it drops under 4 amps to keep it running. The normal amp current for a fuel pump in good condition is 2.8 to 3.5 amps.

All load devices will have an amp spike when they first start up. That is normal for all devices that use electricity. Your home, car or any type of equipment that uses electricity to make devices, like lights, relays or motors work, will draw amps of current when switched on.

When a working load doubles or triples due to an electrical fault, the fuse will do it’s job and fail.

The fuse is a protection device:  A fuse fails for a reason.

A fuse keeps the wiring from being over loaded, getting hot and causing a fire. I have seen some nasty wire fires from car owners doing a repair or lazy repair tech’s that try to MacGyver a failure to get them by.

The tin foil trick, to jump around a bad fuse has caused many car fires. In many cases, a short cut repair will fail quickly or cause more damage. It’s a risk you take when you do a MacGyver repair.

Replacing the starter solved the clients issue.

It’s just a fuse.

Fuses fail for one reason, they are over loaded past their amps rating.

Many times a year I have vehicle owners drive in and ask us to look at their fuses. A fuse does not fail just because it’s old. They fail due to the load placed on them. 20161117_154934_hdr.jpgOver loading a circuit with aftermarket equipment is the most common reason for a fuse to fail “blow out” In a home, you have 20161118_095112_hdr.jpgcircuit breakers that protect each circuit within the home.

Fuses in a vehicle do the same job of protecting the electrical circuit, but if they fail you must remove the bad fuse and install a new one in the fuse box. Before you install a new fuse, its important to check to see why the fuse failed.20161123_122845_hdr.jpg

(What caused the fuse to fail) Just installing a fuse without looking for the reason it failed is not going to fix the problem. The second most common reason we see fuses fail is due to coins or metallic junk getting into the 12V aux/lighter socket. 20161118_094915_hdr.jpgI have found ear rings, small tokens, and paper clips stuck in the 12V power sockets. A direct short to ground will cause a fuse to fail instantly. 20161121_124842_hdr.jpgOnce you remove the junk from the socket the fuse can be replaced. At our service desk we offer free 12V socket to USB power adapters to plug into the open 12V sockets, just to prevent issues like junk or coins from getting into the socket and shorting the terminals in the socket
.

A 110V inverter to power a laptop can over load an accessory fuse circuit. 20161123_134347_hdr2.jpg.jpgYou do not want to use an inverter larger than 150 watts on a 15 amp fused circuit. Most basic 12V sockets only have a 15 amp fuse to power the socket, and its easy to pop a fuse with an inverter, cell phone, and GPS navigation all plugged in at the same time.

Head Lights – plastics care & refinishing

Frosted, yellow, faded, ugly head lights.

98% of the vehicles today use plastic head light housings with plastic lenses, no glass lenses anymore. As the clear plastic lens age, the protective UV coating on the plastic goes bad and starts to fade or frost over. Some plastic head light housing do not have a protective film, and they show age within 3 to 5 years from new. 20161111_081537_hdr.jpgWe re-finish plastic head light lenses all the time.

20161111_071929_hdr.jpgNot all lenses can be saved. Rock pits, scratches, and plastic cracking can not be fixed with sanding if it’s too deep into the plastic surface. 20% of the head lamp housings I run across in my shop have major damage and need to be replaced.

Replacing factory head light housings with quality aftermarket units is not super expensive, but the labor to change out the light housing could make replacement out of the question for some budgets. 20161111_081656_hdr.jpgThe process of refinishing the plastic lens is fairly simple, and many parts stores sell DIY kits to sand, polish and protect the plastics.

Doing it your self or paying a repair shop to do this procedure will make your car look newer, and maybe influence you to keep your car vs buying a new one. Looks are everything, and the clients comment right away that it looks like they have a new car again. The second big plus to cleaning and polishing the lenses is your head lights will project farther down the road, You can see better at night.

20161111_084322_hdr.jpgSo here it is in a nut shell, we clean the plastics, wet sand the imperfections out of the surface. Then use a 2 step polishing compound to restore the clear as glass look. Last step is a double coating of wax. Regular car war works fine for this.

Keeping things looking clear depends on the owner washing and re-waxing the lenses, but we can also do that for the client when they are in for an oil change.20161111_084404_hdr.jpg

A/C Cabin Air Filter Ford Taurus “very dirty”

Service and Repairs – A/C Cabin Air filters

20161114_113741_hdr.jpgFilters protect your car from harmful debris that can cause damage to internal moving parts. The engine, and transmission need service regularly to keep them alive and happy. So what about you, the driver? Back in the mid 80’s some European car manufactures started adding air filters to the A/C system. Mercedes-Benz called it a particulate filter and it protected the A/C evaporator core from getting contaminated with hair, lint, leaves, and other nasty things that could get pulled into the air intake of the A/C system. It also protected the inside of the car from dust and oder. Most of all, the clean air was a benefit to the driver. European cars started using “Cabin Air Filters” first, around the mid 80’s. In the late 90’s I started to see them in high-end Japanese cars, and by the mid 2000’s almost all cars had some type of Air Filter added to the A/C system. The filter works great till, till it looks like the one in the picture. A filter can only do its job if it can catch and hold the dirt. This filter is past its way past its prime. looking at it, you might think it’s very old, but it’s only 3 years old, but the car is only used in town and in 3 years has only driven 7,000 miles.20161114_113734_hdr.jpg

Most car manufactures today list a 1 year or 15,000 mile interval for A/C Cabin Filters. Many car owners do not follow the recommended filter intervals. It’s hard enough to get clients to do regular oil changes much less service the A/C filter on schedule.

I have removed filters that had so much junk in them that they have collapsed in-ward and the A/C system is trying to suck them into the air intake. Blower motor failures can occur due to a plugged Cabin Air Filter. Low duct air flow can happen due to a dirty filter. Poor cooling and compressor failure can also occur because the filter is plugged up with dirt.cropped-Dirty-cabin-air-filter-heyanthonyaz.com-2941.jpg

The filter to the right is from a Toyota. The owner did not know that the car had a filter. It was an original filter. This filter is only 2 years old, and is nasty! The air flow from the duct was almost nothing, even on a high-speed. Changing the filters and servicing your car regularly is part of owning a car. Planning for repairs and preventative maintenance keeps your car happy and reliable. No one likes to tow their car to a repair shop, much less shell out money to repair something major, when you could have prevented the break down all together with a well visit to the car doctor.www.heyanthonyaz.com 252

Yep, it’s broken; Plastics…

Plastics, they don’t last forever.

Unhappy owners with broken cars arrive at my shop every month, and the owners just do not understand why the car has broken down. Well, if you drive it, it will wear out…..

Todays autos use lot’s of plastics. Auto makers have always used plastic parts, but in todays cars and trucks plastic parts are used for so many things, it can be frustrating when parts don’t last because they are made of plastic.wp-image-33241149jpg.jpg

Today I have a Nissan Frontier in the shop with a coolant leak at a plastic fitting on the heater core. This is a common thing on a vehicle that is 10 years old or older.

The hard part is informing the client that the engine is bad, because it over heated, due to a plastic part that failed. Using plastics to make a car lighter, and get better emissions is great, but at what cost to the client. I would rather have all cooling system parts made from metal. The auto maker makes the parts out of plastic because it’s cheaper to manufacture.

So what do they care if the part fails and the engine goes bad. That’s why they make new cars anyway.

D.I.Y. repairs done on the cheep?

I have only one issue with a car owner doing a DIY repair.

If an owner of a car is going to try doing A DIY repair, at least be honest about it when it does not turn out the way you wanted.

My only issue is when a car owner does a DIY repair and then they say that no one has been 20160830_113235_hdr.jpgworking on the car.

DIY repairs are easy to spot. It’s obvious that someone was not following a correct procedure.

Fix it right, Fix it once…

DIY repairs are fine when you use quality parts and the correct repair procedure. Short cut the repair and you are asking for trouble.

This nasty mess, in the above image is from using an aftermarket A/C service kit that included sealant. Many of the A/C service kits sold at auto parts stores, include sealants as part of the freon charge.

A/C Sealants are nasty & damage your A/C system.

Plastic failure is getting more common…

 

Plastic cooling system parts can look normal on the outside, but what you can’t see is the plastic is getting heat stressed on the inside and can fail without warning.

20160721_154840_hdr.jpgThis pair of heater fittings is from a 2009 Lexus LX470. The truck was in for normal service and I found a damp area near the hose that connected to the broken fitting in the image. I pushed on the hose to see if it was fitting loose, and the fitting broke apart with no effort. It was ready to fail, but from the outside it looked fine. Plastics older than 8 years of age can fail just like this part did. An engine for a Lexus is big bucks. A failure like this on the road, would lead to engine damage due to sudden coolant loss.
