Problems with 2005 Chevrolet Colorado SERVICE BRAKES, HYDRAULIC

Brakes lock and grind when the truck is stopped at slow speeds. steering wheel turns somewhat to one side when this happens. happens mostly in wet weather but also happens in dry weather. have taken it to the chevrolet dealership numerous times and they say nothing is wrong. *jb

Noticed after driving on freeway for a while that small vibration in steering wheel occurred with low cabin rumble. first time the vibration was enough to make me think i had a tire coming apart. what was actually happening is my front brakes had applied themselves slightly and were getting very hot. upon braking steering wheel shook back and forth very hard. has been going on since vehicle was new. is 13 months old now. dealer has replaced master cylinder, power brake booster, both rotors, brake shoes. has made no difference, everytime i drive any distance on the freeway the brakes get very hot. i cannot hold my hand on either front wheel but a few seconds. rotors steam and hiss if i squirt water on them. is currently in the dealer the fourth time and they don't know what is going on. i get lots of black powder on my wheels after driving on freeway 60 miles. *nm

The braking system in colorado try to stop and the brakes grab and seem to let go and grab again to stop speed about 30 to 35mph there is problem with the brakes i hit someone. *jb

Rattling noise that appears to be coming from the bed or the frame. noise is mostly heard in cooler temps/lightly heard when temp reach above 85 degrees//when putting foot on brake; it feels like the brake has some resistance and truck doesn't want to stop. *jb

Back brakes were gone. replaced on this day. on june 19 2005 brakes were leaking fluid, cylinder was gone and entire back brakes was replaced. july 2005 back brakes were gone again, replaced again. october 2005 both back and front brakes were gone and replaced again. jan. 16th 2006 back brakes are gone again. *nm

Contact states: stepped on brakes and they failed, never slowed down ,and crashed into another vehicle. speed was approximately 30-35 mph in stop and go traffic. this was the first incident of this sort with the vehicle. it had extensive damage to front end with no repairs, is currently in shop awaiting an inspection from gmc within the next 14 days. *ak

A.b.s. failure at 450 miles. *jb

The brakes (with abs) lock up, mostly when it's wet out, but will also do it when dry. the dealer replaced the abs computer, and has made adjustments, but it still does it. *nm

Dt:the contact stated the brake pedal and accelerator pedal are too close together. when he moves foot from the accelerator pedal to the brake pedal the soul of his shoe hangs on the brake pedal. there is not enough room between the two pedals. the manufacturer stated the vehicle is designed for someone with smaller feet. the brake pedal has a curved arm and this needs to be moved about one inch. this happens 25 to 50 percent of the time.*ak updated 11/29/05. *jb

Front brakes showed wear at 7000 miles oil change, parts had to be special ordered , told to drive vehicle til they arrived,, on 1/4/2005 part installed and mechanic test drove, and rear drum drum brakes failed,(pistons "blew out" of cylinders) i have never seen a brake system that was designed so if the shoes wore out and "scored" the drums the pistons would leave the cylinders ,, causing the loss of brake fluid and even with antilock braking system , cause very poor braking, (think if this happened at high speed on an expressway,, with a family in the vehicle),.,.suddenly no rear brakes,,,,,,,,and in my opionon,, just a couple of milimeters more length on the cylinders and pistion could solve the problem,.. but chevy although replacing the parts , says it was due to wear. (i am a us postal rural carrier) i say it is a design fault, mine just happened sooner , and maybe in time to save some lives if they "fix" the problem. *ak
