Brake proportioning valve?
I have a 98 xj, see profile for all specs, that is having brake issues. It will stop but when it sits for an hour or or two when I hit the brake pedal the rear wheels will lock up, from there it only feels like the rear brakes are catching. I have had this problem for a while now, put new front pads, rotors and calipers on but the problem persists. Does it sound like possibly the proportioning valve? Or could it be something else?
