rear brakes

[BG425]

I changed my rear brake shoes and now I hear a grinding noise and it appears that the adjusting lever that goes over the little star locking nut is rubbing on the brake drum. I can't seem to see why.

improper installation, remove drum and recheck your placement

edit: sorry the rest of my messaged didn't post last night... 3100 hit the nail for the rest...

yes that parking brake lever should never be scraping the drum, so it's installation error

pix of YOUR orientation would help; if you provide the year, i'll google a diagram if u can't google for it

------------------------

slight off-topic:

ugh i hate drum brake systems soo many more parts/springs to re-install & if it's a fwd vehicle, you'll also have to clean and relube the rear wheel bearings on some models

dunno y manufacturers still using front disc/ rear drum setups (oops yea, cheaper cost)

I agree with ricebike, but based on what you are assuming that it is the adjuster level? Maybe shoes did not get chance to properly seat in, and sometimes drum can be out of round that can give you the same scraping noise, unless your adjuster screw and lever are ubnormally sticking out. Did you test drive it? The best way to do your rear brakes if you never did them is to take both drums off, and do one side at the time so you can look at the other side if you are not sure.

typical GM setup of a rear brake drum...1985-1998, courtesy autozone online free manual

good luck, protect your eyes w/ some safety glasses d/t those springs back thurr

nice diagram but I am sure he will need picture of completed puzzle

Make sure you keep shoes and other parts clean from grease, there are 4 spots (2) for each shoe on the backing plate where shoes touch the backing plate (put light coating of grease on those spots of the backing plate) also some grease on the threads of the adjusting screw.

actually, there's 6.... see #30

there's #16, which 3100 mentioned

also, put some grease on #14, most forget that metal-to-metal contact area

and on the diagram, #4, where #7 pivots on...

Welcome to AF BG425 !!

As mentioned , thier are several things that could cause grinding. Most importantly is that the shoes are on right.

And nothing realy has changed from 1985-2005 on the drums brakes.

And thanks for the pic ricebike & AZ. lol
