Whle trying to get the service manager at my dealer to replace the brake pads on my '05 Z51, he said he would only replace one pad. If the squeaking continues, he will then replace another pad, etc. I tried to explain that there was a service bulletin (document ID# 1682443) on this, but he didn't budge. He said there was a Corvette hot line that I could call, and the number was in the owner's manual. If they told him to do all four, he said he would. I couldn't find a number for a Corvette Hot-line, so I called Chevrolet customer service (1-800-222-1020). They said they did not know about a Corvette Hot Line. Does anyone out there know if there is a Corvette Hot-Line and, if so, what the numer is? Also, do you have any advice on how to get the service manager to change all 4 brake pads to take care of the squeal?

 

Bring him this document:

This is a new bulletin just released for this problem. GM has plenty of the rear pads in stock, but very limited supply of the front pads inbound from the mfg. GM Parts was not aware of this bulletin and I passed it on to a supervisor and advised them they better get a bunch of fronts on hand asap. If you are having this problem notify your dealer and give them this bulletin # so they can order you new brakes. Remember this is not a recall, but just the information for a dealer to do a repair under factory warranty.

Brake Squeal on Vehicles Equipped with Z51 Package - keywords disc front groan noise pad rear squeak #PIC3320A - (Jul 8, 2005)
Brake Squeal On Vehicles Equipped With Z51 Package
2005 Chevrolet Corvette With (RPO Z51)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Some customers may comment that when they apply the brakes, the vehicle exhibits a squeal noise. This squeal noise is heard coming from the front or rear of the vehicle. Vehicles produced with the Z51 sport package are equipped with larger rotors and harder pads.

Recommendation/Instructions:
Replace both the front and rear brake pads with the part numbers listed below. Both front and rear pads need to be replaced due to the difference in composition of the brake lining material. The existing rotors should be used and it is not necessary to machine the rotors.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

Find a new dealer, this one obviously doesn't know how to work with a customer, especially since there is a bulletin out on the very issue. Also, who the hell just replaces pads on one wheel. Its technically feasible, I just don't know who would do that.

 

It should be obvious by now....your dealer has no idea what he's talking about. Replacing one pad at a time is not only ineffective, but a waste of time for both you and his shop.

And GM customer service is correct...there is no such thing as a Corvette "Hot Line".

 

Run Forrest Run to another dealer. That is not the type of service department I would trust my car with.
