I have a'95 accord station wagon with a leaking master cylinder. I am going to install a new one, but right now I don't have the $, so I just keep putting fluid in it. I was home for the summer and upon returning, the brake fluid was empty and my brakes went to the floor.

I assumed air in the lines, so I bled all four lines at the level of the wheels. My Haynes book says to also bleed the system at the modulator, but honestly, I don't know where that is or how to find it (no diagram in my book).

After bleeding the four lines at the wheels, my brakes still go to the floor...they work a little better, but not much. Is this because I didn't bleed at the level of the modulaor? Where is the bleed screw for it? Or someone mentioned the power brake booster as well.

When the car is OFF, I can pump it once or twice and then the brake "holds"...it does not do so when the car is started.

I'd appreciate any advice or help! Just a college girl trying to get her car to last a little longer thanks!

 

I highly recommend replacing your brake master cylinder. If the pedal sinks, the piston in the bore, or the bore itself, is leaking. This could cause you to suddenly loose your brakes completely while driving. You could kill yourself or someone else. Have it fixed properly.
