I was wondering if you anyone was having the same brake problems that i am facing. Heres the story, first 6 times i went to the track, i had excellent brake feel no problems, but 2 weeks ago i went to race with a new set of pads and almost immediately i noticed that something wasn't right. MY brake pedal would constantly hit the floor board and the pedal response was obviously VERY squishy.

Im not sure if my brake cylinder has received too much abuse and the heat has killed the seals or maybe there s something completely obvious that i have missed, but cant figure out what it is. I obviously bled my brakes before the race and that sort of helped but after 2 laps the problem persisted. I check all my brakes lines and re-bled them, same problem persisted. Then we decided to change ALL the brake fluid, so we bled the system, poured in brand new Motul 600, and at first felt like new, then 2 laps into it, same CRAPPY SQUISHY brake feel. If this has happened to you, please let me know.

sounds like a master cylinder problem.

thats what i was afraid of, my mechanic told me, it might be lack of adjustment on the rear drums...

Given there are no leaks..
those are your two options..
out of adjustment on the drums would be constant however..
the master cylinder is your mostlikley culprit, being the seals on the piston shaft are going, once they get warm, the fluid squirts by = no pressure..
I would go that route and go ahead and adjust your rears..

thats pretty much what i had in mind to do. I just DONT want to have to purchase a new master cylinder.... My turbo money keeps going in other directions...
