Last week at Diablo my front brake had no power, so I bled it, cleaned the pads and rotor and still, no power. Once I got home, I installed new goodridge lines front and rear, also new pads and a new rotor in the front. Back brake is a Hayes Purple with the G1 caliper and it worked fine before the new hose and works even better now. Front brake is a Hayes Mag with the older square lever blade. Both these brakes are used, so I have no idea about their life.
First bleed on the front brake produced a spongy feel. Second, third, fourth and fifth... all produced the same results.
So I did some more research, talked to a few people, and went down today to try again. First I inspected the brake, no leeks, both pistons seem to move,no paint chipping or wetness near the pinhole on the back of the lever body,no nothing. I just bled it at least 6 more times. Still feels like garbage. I made sure to pump the lever, get all the air out of the bottlehose and bleedscrew first, did everything.
I might try ripping apart another Mag I have and switching the levers and then rebleeding it again. Depending on the results, it should tell me if the problem is in the MC or caliper. But that would take a while and the other brake works perfectly so I don't exactly want to go taking it all apart if I can avoid it.
Suggestions?
