O.T. C2500 Suburban brakes (ABS?)

Thanks

That really sounds like you have something mechanically wrong with the rear brakes; are you sure you put the primary shoes on the front? Did you install the automatic adjusters correctly?

Just don't think the ABS system can be your problem.

That's a good question and I wondered about the shoes having two different thicknesses. The thicker shoes are installed on the aft side. It seems like the mounting holes only allowed that position but I do remember wondering if I had them reversed--that is should the thicker shoes have been on the front side??

Thanks for the reply and the help. I've been out of pocket lately--still doing hurricane work here and in Mississippi.

Any time your rear drum brakes are locking up, the first thing I'd do is inspect them for oil from leaky rear wheel seals.

It seems counter-intuitive, but oil on the brakes that collects some dirt will cause the brakes to lock, and slide the tires.

That's what I was "hoping" to find when this problem came up but I couldn't find any sign of leakage of either the brake cylinders or the axle seals. Just plenty of dry brake dust.

Thanks.

I thought I mentioned that it was a '95. Its a late production "95 diesel as there were only 7 available in the US when we bought this one.

I'll take another look but I didn't see any wires coming down to the drum area and I've never seen an ABS light show up on the dash.

I do have the shoes adjusted fairly tight but they don't rub when rolling down the road. I had so much pedal even after bleeding the brakes, I felt the need to adjust the shoes as close as possible to help reduce pedal distance.

I haven't considered the brake cylinders sticking--this machine has over 200K on it with original cylinders. Maybe I should replace those anyway for good measure.

Thanks for the help.
