1994 Plymouth Duster 6 cyl Front Wheel Drive Automatic
My son has a 1994 Plymouth duster / sundance. When you apply the brake it seems like the back brakes come on first, then the front. Once you stop, when you take your foot off the brake pedal, the car won't move. Then slowly the brakes will release. I bleed the brakes front and rear and there is no air in the lines at all. Could this be a porportion valve problem or perhaps a power booster problem? I'm not sure and unfotunately I don't have a repair manual yet. Please help! Thanks. JC
Check front brake hoses, when brakes wont release, open a bleeder at the wheel, then if it spins free, the hose needs replacing, if it stays locked on, replace the calipers, is it a high firm pedal? Does it sink to floor? To test master, open a line there before you open the caliper bleeder, if it spins master may have gunk blocking the compensating port.
