How does a brake pressure differential valve work?
How does a brake pressure differential valve work?
The pressure differential valve is the device that alerts you if you have a leak in one of your brake circuits. But if one side develops a leak, the pressure will drop in that circuit, forcing the piston off-center. This closes a switch, which turns on a light in the instrument panel of the car.
How does a faulty brake proportioning valve work?
They keep the rear brakes from locking up during sudden, hard braking by restricting fluid pressure to the rear brakes. A faulty proportioning valve results in the rear brakes locking up with only light to moderate pressure applied to the brake pedal.
What causes a soft brake pedal on a Dakota?
Even a tiny rust pin hole can cause a soft brake pedal. or about 15,000 km, but not the front lines or rubber brake hoses. Master cylinder has a minor leak for several years now, but not severe enough of a leak, more like seepage down the vacumn booster, that only occassionaly fluid had to be added.
How can I tell if my proportioning valve is going bad?
Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.
What kind of brakes does a 1999 Dakota have?
I have seen this on a 1999 Dakota and the brakes were rock hard. When I speedo was working again. I only have seen an ABS indicator come on last year when the front to rear brake line blew out.

What kind of brake fluid does a Dakota use?
Topped up to full mark with DOT3 fluid. Started truck; pressed on the brake pedal..seemed ok. pedal seem to travelled down a bit more, with engine running. down almost to the floor (but not quite)..and I smelled brake fluid.
