Noisy rear brakes.

[jhellwig]

I repaired the rear brake lines and replaced the shoes on my suburban a month ago. I got the shoes from orileys. The line had been broke and capped before I bought it so the drums were a little nasty but not bad. When I first drove it you could tell the drums wernt round so I ordered new ones. By the time I got around to replacing the drums the rear brakes wernt feeling to bad but I replaced them anyways. Just a few days after I changed the drums the started to squal and chatter and lock up when I came to a stop. I took them off yesterday and everything looked fine. I made sure the parking brake cables wernt stuck and backed off the adjuster on the noisiest wheel a little. Now it still squeals and locks up but not as badly.

What is going on here? All the hardware is new and everything was working just fine before I switched the drums. I have them adjusted properly and the adjusters are working like they should.

They werent the cheapest on rock auto but the second cheapest. I have wondered this. I could take the old drums and have them ground and see what happens.

Did you put the primary shoe (the shorter one) in the front?

The big shoe goes in the back.

Where else would it go if the short one is in the front?

Based on your description of "the drums were a little bit nasty," it is very possible that the new shoes became contaminated with brake fluid since you reused the old drums. I would try a new set of shoes.

New brake shoes need to be radiused to the drum. I would have replaced the drums or had them turned if they would meet specs. Don't skimp on brake work/parts.

There isn't a difference on these.

I cleaned the drums with brake cleaner. The nasty was a little bit of rust.

The only reason I replaced the shoes is because the adjusters were frozen and I had a busted bleeder on one slave so I replaced all the hardware and shoes while I had them off anyways. No one in town had drums when I got the shoes.
