Any help would be greatly appreciated. [Reply]  [Send Email]

While holding the brake pedal down start the engine. If the pedal goes down your booster is OK. Kent   [Reply]  [Send Email]

It has great brakes. Think its the way they work. Last booster that went out engine run rough when brakes were applied. Made vaccum leak. The one that was on it when got it was so worn out wouldnt let run. Had BIG vaccum leak.   [Reply]  [Send Email]
