My sister just bought a 94 Accord EX with ~200k miles on it. Week after the purchase she gets in the car and clutch pedal goes all the way to the floor. I know its a hydralic clutch, so I check the fluid and its dry. I add some fluid and attempt to bleed using the instructions in the Hayne's manual. Now, pumping the clutch pedal doesn't seem to build up any pressure, so the bleeding process is not really happening. Is it possible air is preventing the pressure from building up? Should I try bleeding with a power bleeder? Or is that a waste of time and I should resign myself to the fact that either the master or slave cyclinder are dead? By the way how would i know which of the two is bad? Any help is appreciated.

 

The master or slave is probably leaking. Best to replace both at the same time.
