[s-cars] Help with Brake Problem

[Mark Turczyn]

Doug-

Any fluid on the floor by the pedals?  Leaking master is pretty common--
also broken threaded shaft to brake pedal but from your description it does
not sound like a broken shaft.

You say no drop in reservoir but It may not take too much fluid loss to get
symptoms without a big drop in reservoir.
