Problems with 2005 GMC Canyon SERVICE BRAKES, HYDRAULIC

Tl*the contact owns a 2005 gmc canyon. while driving approximately 10 mph pressure was applied to the brake pedal and the pedal began to severely pulsate. it took an increased distance in order to stop the vehicle. an abs fault light illuminated on the dashboard. the failure has since recurred intermittently. the vehicle was not taken to be examined for the cause of failure and was not repaired. the failure mileage was 24,994 and the current mileage was 25,010. updated 11/22/10 *bf updated 11/23/10*jb

2005 gmc canyon, 4wd. brakes lock up after sitting for a short period of time or when wet. abs does activate, hear the noise, rear brakes lock. went to some of the forums for these vehicles, find out it is common. took vehicle back to dealer (bought it used as certified gm) as the parking brake stuck only a week after i had the vehicle. they replaced the cable, told me i was set. i took the truck home, brakes were very "touchy" brought it back to the dealer a few weeks later (thought maybe it was me) and they charged me $100.00 and said they adjusted the rear brakes, not under the warranty. i called them and had a blow out argument with the service manager to no avail as the brakes were still touchy. i have been living with them until today, when in the rain i had to make a panic stop on the highway. the brakes momentarily locked at 65 mph, truck stayed straight and i was able to let off fast enough. luckily the guy behind me was not following too close, or he would have been under me. situation is getting worse, i have been driving for 35+ years and never had a vehicle like this. *tr

Abs fault comes on intermittently and gm is not responding to our concerns. *tr

Tl*the contact owns a 2005 gmc canyon. while driving approximately 10 mph in normal conditions, the contact heard an excessively loud grinding noise when the brake pedal was depressed. the vehicle inadequately slowed down. the vehicle was taken to an independent mechanic for inspection and they stated that the rotors were defective. the vehicle was repaired. the failure mileage was 32,660 and current mileage was 32,680. updated 02/02/09. *lj updated 02/02/09. *jb

When i try to stop the vehicle after going between 5-10 mph, the abs system "activates" and makes a "grinding sound". it will do this after 3-4 stops and then the abs fault light will come on and the problem stops. if i start the truck and drive faster (15 mph or faster ) then brake, it doesn't do it at the higher speeds. *tr

Rear brake shoes bad at 45,000. replaced drums and shoes. new drums warped after 2 months and 2,000 miles. replaced drums and shoes again, squeaks very loud, drums bad again. replaced drums with gmc drums, brakes bad again after 1 month. took to an independent mechanic after dealer would not fix issue. independant replaced left rear hydraulic and new shoes. stated the emergency brake must be defective. brakes are now squeaking again after 1 month. also slight locking up when backing up after rain, cold, moist weather. *tr

I own a 2005 gmc canyon. three weeks out of warranty the abs system began to malfunction. the abs would kick in for no reason. because it was according to gm out opf the guarantee period there was nothing they could do for me. my private garage told me that this was a common problem with the canyon and used a work around to solve the problem by disabling the abs system because of the high cost of replacing the sensors witch would probably be damaged again when replacing the brake pads. *tr

Dt*: the contact stated there was a loud squeaking noise, while applying brake pressure at any speed. the vehicle was inspected by the dealer who determined the brake pads needed to be replaced. the manufacturer was contacted.

First: hearing impaired driver...premature rear brake lining failure leading to major damage to drums and hydraulic system...second time in less than 53,000 miles on vehicle..resulting in repairs totaling approximately. $2276.00...this premature failure of system resulted from moderate vehicle usage and driving habits, non-abuse of vehicle...a normal driven vehicle life of rear brake linings and associated systems should last 60,000 plus miles on this model 2005 gmc canyon pick-up. the repairing facility could offer no reason or visible reason of this type of failure...the foremost reason that comes to mind is emergency brake being depress and or "riding" the brakes but both of these have been eliminated...so cause is unknown..the first failure occurred on or about 08/22/05, mileage 23,403 and the second occurred on or about 07/17/06, mileage approximately 53,000 miles... *nm
