[Shotimes] Question on brake proportioning valve

[Ron Porter]

Yeah, I would stay with the advice to not use the plugs on an '89 (non-ABS)
car. When my ABS has been playing the "on-off" game, I have done a couple of
hard stops with the ABS off. It's OK on dry pavement (the rears do lock up
slightly ahead of the fronts), but it could be tricky in the wet.

That is what the plugs several vendors are selling do. As long as you have
ABS, that should be fine.
