Brake Issue...maybe RABS idk

[madhouze803]

Hey everyone bought my 92 supercab almost a year ago and when I bought it drove it back to my cousin's. Looking it over front right brake line blew...no issue replaced...next line going to rear blew..we just plugged it and called it good for the time being. This past fall I replaced the replaced all the lines to the rear from the ABS Hydraulic Valve back. New shoes, wheel cylinders, hardware, adjusters, drums. Bled the whole system and brakes were great until a week or so ago. BOTH the brake light and Rear ABS light come on on the dash and when slowing down my truck kinda bounces/pulses (not the pedal). The truck still Stops fine but i'd like to find out what is causing this. I've also replaced the front pads and rotors looked fine. I did a bit of research and sounds like the ABS Hydraulic Valve is going or clogged. Ive read that some people bypass it but cant find any info on it. When I went to autozone to buy new lines i wanted to by pass it by just running a new line from the master cylinder back but the guy there said that when I stepped on the pedal all 4 would lock up.

SO with all that info is it my ABS Hydraulic Valve?
and How do I go about bypassing?

Thanks In Advance

The guy at Autozone must have gone to a four year college. Sounds to me like he has a degree in BS.

Run a line around the RABS valve, unplug the solenoid, and put the bulb in the ash try for when some other bulb burns out.

Thanks, I'll be doing it ASAP. Is there any risk if i don't get to it for a few days? and of course i'll have to re bleed the system right?

Drive it if you feel safe. I know I have to deal with brake vibrations quickly because I won't brake as hard when it vibes.

And yes, you have to bleed them. Should only have to do the rears.
