What 2001 GMC Sierra 1500 HD owners say
Brakes
I reside in michigan and the winters here are somewhat bad on vehicles but this is in no way acceptable for GM to get away with. I was out of town on the 15th of aug about 80 miles from home and preparing to make a right turn to enter onto the highway when the light turned yellow and the driver/car in front of me stopped suddenly and thankfully proceeded to turn hence getting out of my way because when I applied my brakes their was nothing right to the floorboard, I had known what just happened, ruptured a brake line. I proceeded to make the turn and somehow get the truck to stop while going down the on ramp of the highway. Here is my biggest problem with GM`s brake system. Why when 1 line ruptures all of the rest of the system does not work to at least get the vehicle to stop? …
I own a 2001 GMC Sierra 1500 HD sle which I lost my brakes while entering a intersection the other day brought it to a shop to have it looked at they informed me I have rotted brake lines at the ABS module under the drivers side door. The mechanic showed me the rotted lines I took sometime to check the internet to see if there where others having this problem there seems to be thousands of similar complaints. Also the rear leaf springs shackles have rotted out.
