so recently i got my brake shoes and wheel cylinders replaced on my 98 tahoe, and about a week later when i try to stop the pedal goes all the way down to the floor and the brake fluid starts leaking out the rear left. my brakes no longer work. i got towed to the shop thinking it would get fixed under warranty, but they claim my rear axle and backing plate are bent? i saw the backing plate and it is in fact bent but how did it bend for no reason? i didnt go up any curbs, go offroading, or get in an accident. theyre telling me they cant do anything until i get the whole rear axle replaced. why cant they just put a new backing plate on, fix the brakes and forget about the axle?
Maybe when the brakes were done they jacked it up by the axle, which maybe its not the best idea. Somebody could confirm this
If you are kidding with us, this is ticklish I believe it is the axle not parallel to the bottom bracket. The misalignment due to axle working loose from repeatedly undulating routes, harsh cycling, overloading, heavy braking, off-road usage and the like (unless its an imitation road bike) You need a Bike Shop Mechanic to help solve the problem
Quite obviously no one bent the axle by changing rear brake shoes. It's enclosed in the third-member housing. The backing plate *may have been bent when some idiot changed the wheel cylinder. If you have the service done at this same shop make them prove the axle is bent to you. Inspect the dickens out of the rear axle housing to make sure it isn't bent also. If they jacked the truck up and dropped the rear end on something the housing would show a big ding mark somewhere. Axles don't bend by themselves. Also, if the axle were bent the truck would be vibrating so bad you couldn't see straight! That's a fact.
