I am new to the Forum so I may be doing this wrong. But.
I have an 88 LS coupe and the ABS hydraulic modulator has apparently failed completely. Fluid from the master cylinder reservoir moves to the ABS reservoir in twenty or so miles of city driving.
First difficulty is in finding a replacement modulator. Rock Auto has one reman, but it only carries a miserly one year warranty and a price tag of nearly $900.
Second is to determine whether there are any particular tricks or don't do's in the replacement.
Any and all help will be appreciated..
