REAR BRAKE NOISE

[RyanbabZ71]

I have a very annoying noise when applying the brakes. The noise is like a creaking noise sounds like the brake is falling apart. Everything looked fine. The noise is only coming from the drivers side rear wheel

 

Anyone have any ideas?

I have the same problem on my 99 SBEC. It only happens at very slow speeds but hasn't been bad enough for me to look into yet. It is starting to bug me a little.

yea it happens when i am slowly coming to a stop or in the driveway hitting the brake. My initial guess is the caliper

Mine is doing the same exact thing. In the driveway hitting the brake and turning while applying the brake

[RyanbabZ71]

mine is definitly a brake issue. Even stopped it I hit the brakes let go and do it again you can hear it coming from the drivers side rear. Also thats where the parking brake is and I am wondering if that has something to do with it. On mine turning isnt the problem.

I think mine was originally coming from the front Right wheel but now It seems like its in the passenger rear wheel. I dont hear it going over bumps just when slowing down to a complete stop and cornering.

I had my brother verify the noise today. My truck was parked and when I applied the brake to put the truck in drive you could hear it.

 

Maybe friday I will have time to see if I can detect anything.

'02 Chevy Silverado, Brake Eater

 

Q: My ’02 Chevy Silverado K1500 eats the right rear brakes. The truck has only 43k miles and I’m now on my third set of rear brakes. I had to replace the right rear brake rotor at 18k because I didn’t hear the brake pads grinding and it damaged the rotor. The truck didn’t even make it to 30k miles when the right rear brake was worn out again. Now with 43k I am looking at another brake job on the rear. The front brakes look like new and the left rear was never more then 75% worn, but was replaced each time when the right rear brake was replaced. The mechanic says this is a problem with GM trucks and that it doesn’t matter what brand of brake pads I have put on it will still wear. What’s the deal? Doesn’t GM know how to build trucks that don’t eat up brakes?!

 

A: Oh yes, that infamous right rear brake pad problem. GM has had a problem with the rear brakes on their light duty trucks. There is a fix. The ALLDATA Information System shows GM Technical Service Bulletin # 00-05-23-005B, which to simply describe is a mud flap kit. This kit addresses rapid brake pad wear problem that is found on most GMC and Chevy trucks made from ’99 to ’04. The right rear brake caliper and pads are located in such a manner that road dirt flies right into the brake pads. This steady diet of dirt causes the brakes pads to wear out really fast. The GM mud flap kit is installed to block bombardment of road dirt and debris that is causing the brake pads to wear out so quickly. The GM kit part number is 15765007 and is pretty easy to install. Before your next brake job I would suggest installing the mud flat kit. I think if you check with your dealership they be very agreeable to install the mud flap kit.

This bulletin is being revised to change the content from Informational to Technical. Please discard Corporate Bulletin Number 00-05-23-005A (Section 05 - Brakes).

 

Condition

Some customers and dealers may comment on accelerated rear brake wear on some of the above listed vehicles. This condition occurs mainly on the right rear inboard brake pads and on vehicles that are exposed to extensive off-paved roads.

 

Correction

Install a mud flap forward of each rear wheel using the following procedure. Installation of these mud flaps and following the recommended off-road driving information provided in the vehicle's Owner's Manual should greatly reduce the possibility of accelerated rear brake component wear.

 

 

Important

Always work from outboard to inboard, drilling one hole at a time and securing with a fastener. Follow the sequence of the procedure. This will prevent distortion of the mud flap.

 

 

Raise the vehicle. Support the vehicle.

Locate the pickup box side panel rear brace.

Remove the existing outboard upper fastener on the brace.

Install the mud flap through the "V" of the brace. Install the previously removed fastener in the hole (2) of the mud flap to the brace. Do not tighten the fastener at this time.

 

 

 

Using the mud flap as a template, locate and mark the location of the hole (1) in the pickup box wheelhouse.

 

Important

After drilling the holes, apply the appropriate anti-corrosion primer. Refer to the GM Refinish Material Booklet #4901M-D (English) or #4901-D-F (French) for additional information.

 

 

Center punch the marked location and drill a 6.35 mm (1/4 in) hole. Install the plastic retainer in the hole (1) of the mud flap.

Tighten fastener at the hole (2) location of the mud flap. Tighten

Tighten the fastener to 25 N·m (18 lb ft).

 

 

 

 

 

For vehicles with short box, use the following procedure:

Push the mud flap to make contact with the rear side of the underbody cross sill and mark the location of the hole (3) of the mud flap.

Center punch the marked location and drill a 5.159 mm (13/64 in) hole.

Install the screw. Tighten

Tighten the screw to 4 N·m (35 lb in).

 

Repeat the above steps for hole locations 4 and 6.

 

 

 

 

For vehicles with long box, use the following procedure:

Push the mud flap to make contact with the front side of the underbody cross sill and mark location of the hole (5) of the mud flap.

Center punch the marked location and drill a 5.159 mm (13/64 in) hole.

Install the screw. Tighten

Tighten the screw to 4 N·m (35 lb in).

 

Repeat the above steps for hole location 6.

Repeat the above steps for the opposite side.

wait a second so its just a mudflap? I already have mudflaps so the rear wheels will have a total of 4 mudflaps then? That doesnt sound right

[Z71GUY]

Let me give you some sound advice... pull off ALL 4 tires and check your rotors and brakes, especially the inside part of the rotors. I just turned 50k and replaced my brakes.... my rotors were absolutely horrible!!! Also my rear pads were pretty much gone.... I also had some strange brake noises....since I changed all the rotors and pads, the noise is gone and my brake performance is MUCH MUCH better.

 

 

GM really put some POS rotors and pads on these trucks.... all my friends with a new body style GM truck has found the same thing when they approach 40-50k.

I also have mud flaps. I only have 19,000 miles on my 2002 and your saying my brakes are gone. Chevy = POS

[RyanbabZ71]

this noise is driving me nuts now. Especially since its nice out now and i am driving with the windows down. I also notice the noise when depressing the brake pedal.

 

Oleander I had my rear pads changed out at 19K miles under warranty because I had a squeek (minor compared to the noise now) in the drivers side rear brake.
