Hi there,

Check fluid level, if low check for any leak, re bleed system if still poor pedal, you may have a faulty master Cly that is by passing, (fluid leaking past internal seals of the master Cly) if this is the case, normally you can test by turning off engine and pump pedal till all vacuum expelled. Pump pedal up till firm and hold light but steady pressure in pedal, if by passing, pedal will slowly sink to floor.
