if your leaking p/s fluid it must be a hydraboost system. poss hydraboost rear seals are bad

is your pedal spongy if so you probably need a master cyl

CORRECTION...a spongy brake pedal does NOT mean a bad master cylinder...a LOW or SINKING pedal are signs the master cylinder is failing. . . And leaking POWER STEERING fluid will NEVER cause a master cylinder to fail!
