Brake Screach

The rear brakes on my 98 2500 4x4 screach whenever I brake going in reverse. They also occassionally lock up when I apply the brakes going forward slowly. They are worse when it is wet out and/or first thing in the morning. This is very annoying when plowing. The shoes and drums looked fine, but I replaced them anyway along with all the hardware. However, it still does it, but it doesn't seem to be as bad yet. Does anyone have an idea of what the problem could be? The brake cyliders don't appear to be leaking or seized. Thanks in advance.

Re: Brake Screach

Rust? A groove worn into them? Bad hardware? It could just be the quality of shoe too. If you want silent brakes try some Wagner Thermoquiets.

Re: Brake Screach

Could be one of several things....I had similar problems with my 98....

1. A little seepage from the axle seal getting on the drum/brake shoes (only takes a tiny bit) will cause em to lock up like that at real slow speeds. (this was part of my problem) VERY annoying!! Do you park sideway on any kind of hill??????

2. Wheel cylinder needs rebuild. Leaking or sticking.

3. Build up of brake dust. I used to have to take mine apart about once a year and clean them real good or they would make noise. (I would clean them up while in there checking for gear lube seepage)

4. Glazed shoes or drums.

Or I spose it could be the proportioning valve.....but I'd say it is the least likely.

Re: Brake Screach

Thanks. I don't park on a hill, but I may need to check for axle seal seepage.

I agree with all of what Cosmo said.

I'd check the first option there first. That's what happened to me and I had the same problem as you.

Re: Brake Screach

I have the screeching on my 96 1/2ton. I found my drums were over the recommended max diameter and the brake shoes were wearing on the ends. I decided to go with disc brakes. I just received the kit from http://www.blackbirdscustomtrucks.com/index.html and am looking forward to installing it.
