Asked by Jul 03, 2015 at 09:34 PM about the 1998 Chevrolet C/K 1500 Cheyenne Extended Cab SB

Question type: Maintenance & Repair

No rear brakes on my 98 chev 1/2 ton 4x4 Z71. Replaced shoes still no brakes. There is
no fluid from ABS module to rear brakes. Chevy dealer said I probably couldn't get a new
module. Is there a way to bypass?

No you cant by pass the ABS module,but if you check online,like ebay,or some of your local salvage yards, you can get a used one.


Yes you can bypass it, locate the main pressure brake line for th rear brakes, follow it down to the first connection at the rabs valve, and remove the valve assembly, then Amal you have to do is make up brake line replacement and bending to fit, and when you are done it is just like the brakes were back in the 70's, so beware as you can lock up the rear wheels really quick, you can also put in an adjustable rear proportioning valve if it is too intense.

Oh, yes you can bypass it. You will have to make your own lines to make up the gap left by the module. Or you could get a module out of the salvage yard.


Yes you can by-pass the abs unit. Wilwood sells a really neat proportioning valve that totally eliminates the abs unit. You do have to re-plumb the under hood lines though.
