Hello all,
I'm begging the advice of the experts on this one. A friend of
mine just replaced all four wheels of brake pads on his Daytona.
All he did was remove the pads and put new ones on, and he suddenly
found his brake pedal going to the floor.
Thinking that the pressure he put on the caliper pistons may
have damaged the old master cylinder, he bought a new one and
installed it. The master cylinder had good pressure when he bench
bled it, but it fared as poorly as the old one. Apparently, even
when he pumps the brakes, the car does not gain pedal pressure.
He bled the lines quite a few times, and he can find no leaks to
speak of. The car has a power brake booster, and after testing it
still holds pressure with no leaking. He was thinking his
proportioning valve may have gone, but I suspect a faulty hose
somewhere. Since we can't find any dripping fluid, he's less than
thrilled about the idea of buying four new rubber hoses for the car.
Anybody have any ideas?
(The car has four wheel disks and no ABS, BTW.)
Thanks!
Mike Lishego
