Brake Disc Caliper Problems of GMC Yukon

On 9/25/18 while applying brakes the brake pedal became extremely hard to press and very hard to stop the vehicle. Thank god it was in my driveway this occurred. My significant other came home from work on 9/27/18 and changed pads, lubed caliper sliders, and verified proper caliper operation. Spent 9/26/18 talking with the dealer and checking recalls. All these repairs were suggested by the local dealer, by them of course. Upon test drive after new pads were installed, the same issue happened. Driving forward the brakes operate as they should or at least feel normal.

On repeated occasions (from 2015 to 2019) I have experienced sudden acceleration at low speeds and sudden jerking motions. The transmission and speed controls are unpredictable and dangerous. This is hazardous and may result in a loss of control. I have also experienced numerous issues with the brakes including a stuck caliper at approximately 42,000 miles. I reported these issues and numerous other issues to GMC corporate, tustin Buick GMC only to be told that it was a software issue and things are satisfactory and safe. GMC contends that the vehicle is fine and declines to assist with issues. This is an ongoing issue. The date below is approximate. The mileage is approximate on all entries.

Steel brake lines have rusted through, causing leakage and total brake failure during application. Calipers and bleeder valves also rusted, preventing new brake lines from being re-attached.

Driver side front rotor outer surface has full metal to metal contact with zero brake pad material and had to be pried out. Driver side front rotor inner has uneven partial surface contact with rotor and is jammed in the carrier (unable to remove by hand, had to be hammered out of the carrier). Passenger side brake rotor outer has perfect surface but brake pad looked brand new. . . No wear on it and is jammed in the carrier. Passenger side brake rotor inner surface has partial contact with brake pad. . . Heavy thick rusty ridge formed and brake pad showed ridge impression on it. Customer said the brake was done by dealer two years ago. The main culprit is the brake pads are jammed in the carrier because the brake pad backing plate is too long to insert or to move freely. There is some kind of design flaw/specification problem. The driver side required much more shortening of the new brake pad backing plate than the passenger side. Brake pad tab width was perfect and moves easily with no play. It is only the length of the brake pad tabs are the issues. I am not sure if the brake pad/caliper carrier is at fault. . . Possibility of bending or twisting that may cause the issue of brake pad being jammed, or too long to insert. It is such a strong metal that there is no way any human can physically bend it nor simply dropping it. It would take a severe force to actually bend the carrier such as the vehicle itself under repeated braking. I think this is the most plausible reason for this situation. New brake pads has same problem. . . The length of the backing plate tabs are too long to insert into carrier on driver side and they do fit too tight in passenger side carrier. We had to shorten the brake pad tabs to allow the pads to move smoothly in the carrier.

Excessive corrosion on brake calipers, bleeders and all bolts are rusted and unmovable. Brake lines are rusted and leaking.

Brake lines failed while driving through parking lot. The vehicle stopped just short of colliding with other vehicles in the lot. All lines including transmission cooler lines and lines from calipers to brakes needed to be replaced due to excessive corrosion.

Was driving down my street @ 20mph, started to brake about 150 feet before the stop sign. The brake pedal went to about 1/2 to 3/4 inches above the floorboard before I came to a stop. . . About 5-6 inches of pedal play. I immediately traveled to my auto repair business doing a lot of downshifting and slow speed travel so as not to cause further damage or an accident. My abs has been disconnected due to corrosion and the prohibitive cost of repairing/replacing it(approx. $1600!!). I just drive cautiously just like when abs didn't exist. The technician inspected, he found 2 failed leaking steel brake lines. . . The rest of the brake lines were severely rusted. The tech re-constructed the brake lines from scratch using a corrosion-resistant alloy tubing. This tubing should not need replacing again. Tech also labored and extracted brake bleed valves from calipers. These were tiny rusted nubs. Tech re-assembled, filled and bled the entire brake system, re-tested for leaks and proper operation. All replacement lines were custom-bent from bulk tubing. The bleeding process took over 2 hours because the abs unit was in-operative. 10 1/2 hrs of tech's time was used. The actual brakes and components at the4 wheels remain unchanged. The entire bill came out at close to $1100 but was discounted by $200 due to customer loyalty,thanks!!! there are close to 900 complaints already concerning this problem with these full-sized gm products. Yes I do live in the so=called rust-belt( cleveland ohio area). But I do know that this incident could have resulted in an accident had it occured at a different time and location.

Brake pedal went to the floor when applied at 30 mph. All lines and hoses were severely corroded, not merely surface rusted. Brake hose nuts rusted to calipers, could not be removed, requiring 2 calipers to be replaced.

Broken/leaking brake lines due to severe underbody corrosion: frame,brake and gas lines, front suspension, spare tire assembly, nuts, bolts, exhaust pipes, etc. Along with this I replaced two transmissions, once due to radiator failure, fuel pump failure, brake caliper failure, a few sets of rear parking brake shoes because the adjustments dont work properly, three window regulators and all within 163,630 miles. Yea I'm pis@#$ off.

2003 GMC Yukon xl denali brake lines rusty and burst while wife was driving and lost brakes. This caused a very dangerous situation. About a year ago the dealership replaced several brake lines due to the same problem. Also they replaced the calipers due to rusted bleed valves. They are using substandard materials and making a very dangerous situation for people that drive gm vehicles.

The front calipers are sticking, the brake pads have been checked and one is worn half the thickness of the other. Nlm.
