I have a 92 camry with front disc and rear drum brakes w/ no abs. I changed my front pads and noticed that my right caliper was leaking. Replaced caliper. Bled brakes. 2 days later my brakes start fading. Replaced master cylinder w/ rebuilt. Bench bled master cylinder. Bled brakes according to Haynes manual starting with right rear, left front, left rear and right front. Same problem. Replaced brake booster. Adjusted rod. Same problem. Could not get any fluid out of left rear and right front bleeders. Confirmed not plugged. Replaced proportioning valve. No change. Decided to bleed directly at master cylinder. Fluid only came out of side port not front port. Returned master cylinder and got another one. Same problem. Everyone tells me I must have air in my lines, but if fluid isn't even coming out of master cylinder how could that be the problem. Anybody got any help for me?

 

Figured out my problem. Got two bad rebuilt master cylinders. Bought brand new one and everything works good.
