accumulator ball?

[jerrad]

When I turn the ignition on and motor off I can here the powermaster motor running for quite a while(10-20 seconds). Also when I press the pedal very hard to build boost on the line the brake light on the dash will stay on until I tap the brakes. Could this be the accumulator ball? I bled the brakes a couple days ago but it didnt help. Thanks

Most likely it is the accumulator. Hard to find part now. But rumor has it that a source has been found. I actually bought a used one this summer to replace my failing accumulator. Don't drive the car until you fix it. You may burn out the electric motor and/or loose your braking all together.

good luck
