It feels like my brake pedal travel is too long. Braking is good, but it takes more and more pedal travel to get the same braking force. I bled them after the last track day and they feel better, but still not firm.

When I use the pressure bleeder, the fluid drips out at a faily low rate - it definitely does not shoot out of the bleeders. Should it? I pump up the bleeder to 15-20 psi. Maybe I still have air. Would manual bleeding by pumping the brakes and bleeding help?

I don't notice any loss of brake fluid, so I don't think I have a leak. Any ideas???

Thanks,

Doug

Check the rear rotors. They will develope a small lip on the outer edge, and when the lip gets to large, the pads will not contact the rotor correctly, and the result will be increased pedal travel. A quick diagnosis of the master cylinder is the pedal will continue to fall to the floor under light pressure, rather than stop falling as it should.
