Hey guys i have been having some problems with my new 87 turbo t. when i first start my car i get alot of pedal fade which then goes away after the car warms up. also untill the car warms up the light stays on. i wanna know whats the problem cause i have been told i need a whole new master cylinder but i am questioning that. any help would be apreciated.
Most likely it needs a new accumulator bulb on the side of the master cylinder. Try that first..
My experience with these problems is that the cause is internal leaking inside the booster. A new accumulator might temporally fix the problem but a fading warning light is an indication of pressure problems.When the light is on is the pump also running? Or does it cycle normally? The two things that cause this are a worn pump and motor or one of the o-rings on the power piston inside the cylinder/booster. To properly diagnois this you need the fancy pressure gauge to see what the output of the pump is. As you know a new powermaster is expensive. Your old one can be rebuilt. Look under the resources(sorry about no link) for rebuilding tips and instructions. The pump and motor are available new but it is almost the price of a complete P/M. I cant remember who but there is someone out there rebuilding these too.
There is no such thing as a rebuilt PowerMaster motor/pump! Please check my web site for details and price for NEW PowerMaster motor/pumps.
Thx,
Hank
Thanks Hank, Your'e the guy I was thinking of. Sorry about the mistake.
No problem Eric. I've been lying low because I usually come across too brazen when I post. I'm always available to help though.
