PM Brake Problem

[FreeBoost]

I’ve got a problem with my Power Master brakes. The car sat idle for over a year. I went to move it and found that the reservoir was almost empty. The brake pedal goes to the floor with no back pressure and when the pedal is pressed the pump runs and the brake warning light comes on. There is no fluid on the ground. The car has the replacement brake switch. Adding fluid didn’t make any difference.
My guess is somehow the accumulator has failed and the fluid went into the accumulator.
Any suggestions? Vacuum conversion is not an option since the car is a GNX.

You may have to look for a used accumulator on line. I have tried all kinds of ideas, including using a Teves IV accumulator with an adapter. Nothing worked. Eventually, like others you may be forced to switch to vacuum or hydroboost. I switched to hydroboost and never looked back. But before you switch, try rebuilding your master cylinder, maybe one of the seals is defective. Sorry for the bad news.

Kirbans sells a replacement accumulator. Click on catalog. Then on suspension,brake and wheel parts. Hope this helps.
