Basically, when the valve goes bad, the rear brakes do not work. Unlike front heavy, front wheel drive cars, the rear brakes do a significant amount of stopping. There is a test procedure for the valve. You just need the 3,000 psi test set. (Right!) A simpler test is to apply the emergency brake while stopping with the foot brakes. If you can easily get a noticeable increase in stopping power with the handbrake, it is likely the pressure regulator is going. At 17 years of age, it doesn't owe you much anyway.

RE: Brake Pressure Regulator and 'soft pedal' Dennis, can you be more detailed in your description of this kind of failure? I ask because I'm about to try to define a problem in my '90. Not really a soft pedal but maybe a little bit, but the main symptom is that the brakes just don't work they way they should or used to, not getting the braking power I used to unless I really stand on them. And the rears have been checked and adjusted, no problem there. |
