Rusted out Back Plate on Parking Brakes

Replacing parking brake shoes and hardware

Rusted out Back Plate on Parking Brakes

Postby wmazman [OP] » Apr 07 2010, 1:02am

I am in the process of replacing parking brake shoes and hardware. During the removal of these parts I discovered the backer plates are too rusted to attach the new shoes. The Haynes repair manual doesn't cover this topic. It looks to me that the only way to replace them is to remove the axles. I have the left side apart up to the point of pulling the axle. If anyone has any input that may help me along the way I would certainly appreciate it. Thanks!

I don't know, man. Start hitting them with a big freaking hammer is what I usually do. Rust is a common issue when replacing the brake shoes. Get some rust dissolver and a hammer and go to town trying to break them loose.

I havent actually done it on a Silverado but if it is anything like i have seen on other GM trucks with rear disc brakes, you may have to pull the axles and replace the backing plates. The cost was not to bad for that part but the shoes have a wide range of prices. Probably a good time to get new fluid in the rear axle anyway, right?

does the parking brake even need to get replaced on a scheduled basis? I have never on any of my vehicles done so..or is this something that u do just to give u peace of mind?

What happen was that the shoes broke free and jammed up inside the rotor. Good thing it happened in my driveway cause the truck wouldn't even move. I used the 2lb sledge routine to get the rotor off. The rotors and pads don't actually look too bad but after beating it with the hammer I'm going to replace them. I also pull a 5th wheel camper so I'm going with the ceramic pads. Thanks for the feedback.

I had the same thing happen to me last week on my drivers side back rotor. The emergency brake shoe got held up in the rotor and I used PB blaster and a sledge to get it off. I ended up just prying the shoe off and not replacing it. Well now its making a annoying ticking sound so I am gonna have to go back and replace it most likely.

What kind of brakes do you recommend? i figure sometime in the future, i will need to replace mine and i have been told different things about brake pads. what is the real difference between, metalic, semi-metalic, and ceramic? I had metalic ones that came with my drilled and slotted rotors but the always sqeeked. any input would be greatly appreciated.
