1989 Jeep Cherokee mileage: 125,000. I have had an on going problem with the brakes, I changed master cylinder, power booster shoes and pads and still the brakes are not great. No matter how slow I am going and how hard I press the pedal they will not lock, when going down a steep incline they have a hard time slowing the car down. Yesterday when pulling out of the garage the rear wheels locked when I just touched the pedal. I have been told to check the proportioning valve, but I thought this was just for emergency braking. Any info would be appreciated.
