so in an effort to fix my 'deep' pedal brake problem, I decided to replace my master cylinder...also based on many suggestions that it was bypassing, making the pedal spongy, travel way deep to brake, et.

..but thats not it, why? cuz I just replaced it with a new one, no change, even after being bleed twice.

now im wondering if it is the power brake push rod, needing adjustment to get the force back up at the top of the arch of pedal travel.

Anyone ever have to adjust this?
Any other ideas, ABS is bad, what...anyone ...Bueler?

 

wow, nobody?...nothing?

 

are you sure your bleeding it correctly? perhaps you got a leak some place, try putting some of that special uv light stuff in your car and using a black light to try to track down the problem.

 

no leak, it holds fluid fine...here is a new theory i have, that is the PBV (proportioning bypass valve)... but im speculating

this valve makes it give more force to front/less to back...and I noticed my fronts dont look as worn as my back, and it should be opposite, especially after a few good tack events..... so i wonder if that is it?

Ohh, well, i have a master cylinder FS if anyone needs one :-)
