My 1969 camaro at one time it was all wheels drum, I replace the from drums with front wheel disk brakes, i had gone with three master cylinders and two power boosters and for some reasons my brake paddle still goes down to the floor giving me minimum brake to stop the car, I had taking the car to the mechanic and they can`t find the problem, went I bleed the brakes is stronger but after a while of driving it goes down again, I don`t notice any brake fluid missing so I must be loosing air from some place can any body help me on this one
Thanks

When you changed the master cylinder did you use the right push rod? There are differant ones. Just a thought. :)

If you bleed the brakes and it goes from a high pedal to a low pedal with driving miles and there are no fluid leaks, the most common cause is the master cylinder seals bypassing internally.
What type of calipers do you have, and what type of master cylinder?
-
make sure the bleeders on the calipers are pointed to the top. if they are pointed down you cannot get all the air out. been there
