Emergency brake problem

2004.5 Silverado 2500HD 101,000 miles. Around 5000 miles, and five years ago, I took the truck to the dealer for a new serpentine belt, cooling system drain and flush, transmission service, and a general check-up. At this time, I informed the dealer that the emergency brake was not working and asked them to please check it as well. I was told that axel seals were leaking onto the brakes. A couple of thousand dollars later, I took the truck home and put it in my shop until Elk Season. I have put about 5000 miles on the truck in the five years since this work was done. I am currently trying to sell the truck and Lance Camper, and found that the E-brake is not working again. I looked at the work they had done on the brakes, and saw that they had done a complete brake job with new rotors, pads, and E-Brake shoes. I stopped by the dealers and qot a quote of $159 to adjust the brakes, ok fine. I took the truck in, and later in the day, I got a call and was told that it may cost over $400 if they had to replace the rotors. This guy was unaware of the past work they did. I told them I'd be in in the morning to get the truck and not to do any work. Net day, I went in and explained to the service guy what had transpired, and he said he would go talk to a tech. The guy came back and told me it may cost $800 to fix the E-brake. I took the truck home and called an independent shop. This shop told me that for $200 and change, they would diagnose the problem and give me a quote. I asked if the $200 included anything besides looking and got a maybe if necessary reply. Is this a common malady with this E-brake design?

Customer arrives at a shop with coolant pouring out of the radiator. Asks what will it cost to get this fixed? Well, the shop says, $200 to diagnose and then the cost of the radiator and labor on top of that.

Seems like this is getting to be standard operating procedure for many places and situations these days.

As for your situation, no one knows what the problem is until they take your e-brake apart and see what the problem actually is: cables and adjustment, leaking oil, broken or faulty parts, etc. If it were easy, you could do it yourself.

Use this and see what information about the ebrake is available for your year of truck.

In my experience, the parking (E) brake not holding well is a common issue with the Silverados and Sierras or really all the platforms that use the same design.

They aren't self adjusting, least up through LMM. Haven't had a chance to work on LML or L5P to see if they changed anything.

I always found it easier to pull the rotors and make the adjustment to the stare wheel rather than through the access hole. This can be difficult if the rotors are worn and have grooves in them.

yeah,trying to remember which way to move the adjusting star is always fun.especially when its years apart when needed to be done.and the driver side just plain sucks to do.
