My friend's '87 Limited T has a problem with it's powermaster unit.
Brakes became soft and the 'BRAKE' light would come on under moderate braking. Then, the brakes suddenly became very hard and the brake light is now always on and the pedal is stiff.
Meineke didn't want to look at it, and said to bring it to the dealer. He did, but they're having trouble diagnosing it.
A fuse in the system keeps blowing. If the fuse is replaced, the system 'pumps itself up' (their words) with pressure until the fuse blows again. They think it's the Accum. ball and/or a thermal switch.
Anyone have any ideas? If we can't figure it out, we'll buy a complete unit off the board here, but if it's something simple, it would obviously be better. He doesn't want to waste money on something that won't fix the problem.
Thanks,
Kris
