Rear brake issues

quick6black · 07-02-2009, 10:16 PM

I have been having a problem where one wheel will lock up in the rear. Here is what i have done so far, replaced front caliper, rotors, pads. Rear brake lines, adjuster rebuilt kits on both sides, new e-brake cables from the braket under the bed to the drums, and new shoes.
All that stuff needed to be replaced and I have had the problem for about 3 years, only becomes problematic in the rain and snow. Truck is a 1994 4wd 2500, with 4 wheel ABS, that does not work. Any thoughts would be appreciated

thanks,

Cant help, but im definitely going to keep an eye on this thread... having a similar issue with my truck (only RWAL)

The truck has always been bad for locking up one or both of the rear wheels on slippery surfaces, its especially BRUTAL after some rain, the damn thing will almost lock up with the slightest pedal pressure and almost put ya through the windshield...

Just recently my brake light/abs lights have come on after some rain...

Im suspecting possibly a short in the wiring somewhere and the rain is effecting it...? Since you have 4wabs you have twice as much wiring and sensors to deal with, i pitty you...

Have you tried bleeding the ENTIRE system? (following this 'proper' method ABS Brake Bleed Procedure) i have read about some pretty funky symptoms when their is a bit of air or a chunk of junk floating around in the abs system

Found another nice writeup here, not sure if that particular system is what the dodges used for 4wal though. its the same company that makes the RWAL system for the dodges...

thanks for the info, I forgot to mention that presently my ABS does not work. I need to replace one of the front wheel speed sensors. One of the bolts broke off in the steering knuckle, going to make a weekend of it doing the ball joints as well. Going to look over the write up you posted, and bleed the system again. Not sure I did everything listed there

dodge is famous for leaking seals, and the rear axle seals are no exception. Mine were replaced under warranty at 25k, and are leaking again. The '67 d200 I had in high school did the same thing. Any oil contamination on the brake pads make them sticky, especially the first time in the morning. You can get in the habit of using them lightly at first, but it's better just to replace the seal and pads.
