I have been having ongoing problems with the brake system ranging from mild to severe vibration felt on braking. The discs and rotors and drums have been replaced 3 times in under 40000 miles. A number of other trips to the dealership have been unsucessful in correcting the problem.
Brakes deployed at will...fail at will....sometimes fail to release, causing vehicle to become immobilized....strong burning odor...scary noises and thumping
I purchased my vehicle brand new. Within the first 18 months of ownership, my brakes were replaced three times with numerous other parts changed. The vehicle was pulling to the right when brakes were applied. Although I have not had any trouble within the last year, the truck still does not stop like it should under normal braking conditions. GM gave me an extended warranty to cover the cost of any extra repairs, should the need arise. I would like to know the results of the brake evaluations on the GMC trucks. Thank you.
