2000 NB, no ABS. This started very suddenly today while at AMP, went from a firm pedal to a soft one in the space of a session, and progressively got worse despite a quick bleed in the parking lot during lunch.
Symptoms: Very, very soft brake pedal. The first 2/3rds of pedal travel do absolutely nothing, then it kinda grabs in the last 3rd.
System is COMPLETELY bled. I even enlisted another person to pump the pedal while I cracked the bleeders- bled all four, starting from RR, moving to RL, FR, and lastly FL.
NO ABS
Redline DOT4 fluid.
Rear is completely stock lines, calipers, rotors. Front has Wilwood calipers, stainless lines, new rotors.
With the car off, the pedal is stiff and firm. Once I turn the car on and the assist kicks in it sinks right to the floor.
Not leaking any fluid, level in the reservoir remains the same.
The only two things I can possibly think of are:
A: Redline fluid is junk(doubt it).
B: Stock rubber lines in the rear are "ballooning" and bye bye all my pressure(also doubt it but have not observed the lines while under pressure).
I have a willwood proportioning valve that I did have set "neutral", stock pressure to the rear. I cranked it all the way in to "cut off" the rear brakes and see if the pad stiffens up or remains soft... hopefully that will help pinpoint the issue?
Any other ideas?
