I'm going to have to replace the vacuum brake booster in my '86 951. The brake pedal takes a lot of effort to stop the car. The booster gets and holds vacuum and the brake fluid is recent and is holding.
I pumped the brake pedal several times with the engine off to bleed off the vacuum in the booster and applied moderate pressure to the brake pedal and started the engine and the pedal had almost no movement.
Has anyone replaced the booster on their 951 that could give me some pointers and some advice or does anyone know where I can find the procedure on the net?
There sure is alot of stuff around the booster and any help would be greatly appreaciated.
Thanks, Threesticks.
