If your brakes feel spongy, fill the master cylinder with brake fluid (make sure it is the same as in the master cylinder -do not mix dot 3 with dot 4 fluid) then try bleeding the line. If the brakes do not come back in firm, it may be time to repair or replace the caliper. Another common problem is the brakes lock up. What is happening is the piston does not retract and stays in the "applied" position. This puts a constant pressure on the rotor.
have you tried the proportioning valve. sometimes dirt will get in there and clog the returns.
Answer: Brake calipers (front or rear) normally "go bad" because the dust seal was not replaced, thus allow dirt to get onto the piston as the brake linings wear down. When you go replace the linings and DON"T clean the piston, it allows the dirt to damage the caliper bore. NORMALLY, brake calipers leak and can be overhauled with a few sealing rings, and a good bleeding of the brake system.
You push the brake.
Step on the brake pedal? Not sure what you are asking.
You should use DOT 4 brake fluid for dirt bikes. This is the most common type of brake fluid available on the market.
