No Rear Brakes

[johnnybronco]

'89 B2. Rear brakes shoes are not moving. Pulled the bleeder valve and got about a spoonful of fluid after pumping the brake pedal 50 times. Replaced shoes about 3 or 4 years ago. They were working then. Master cylinder is only 3 years old. I'm thinking brake lines are clogged due to old fluid/never had a complete flush/age? Anybody have other ideas? I've never looked at brake lines before, but then I've never had a 37 year-old vehicle before.

My rear brakes weren't getting any fluid at the wheel cylinders.

It ended up being a clogged Rear Anti-Lock Brake System (RABS) solenoid (along the drivers side frame rail).
I removed the solenoid, but kept the electrical part...otherwise you will have a constant warning light.

Thanks, I'll give that a shot. My rear antilock light has been on for ever

When you say you removed the solenoid do you mean the part that has 1 line running into it from the master cylinder and another running out to the rear brakes and wiring plugged into it?

I gutted my RABS solenoid, but it looks like this:

After bypassing the solenoid, I noticed I had an indicator light on the dash.
Retrieved the disassembled solenoid from the trash, and plugged it back into the original connector (It's more then one wire).
No more indicator light.

This is the thread that pointed me in the right direction:

I have been going through my new to me 1990 bronco II, which had a dead RABS module. I bypassed it and was finally able to successfully bleed the brakes.
I later discovered a constant brake-light on the dash.

Thanks to this thread, I pulled the RABS module out of the trash.
I removed the electrical component off the module, and plugged it back in to the connector on the frame-rail.

No more glaring brake light
