Baffling brake problem
Well this was originally my autocross car now switched to a drag car 79 Camaro/500" Pontiac motor.But you guys are good at brakes.
Last outing this spring in the IA/Camaro ran 10.33@ 132.5 butsecond convertor was still to tight only 60 fting 1.54, so ordered one from Lenny at Ultimate. Car has sat since those runs because of COVID and 100 degree weather. Last weekend get in it to move it to the lift to swap convertors and brake pedal has a LOT of travel and is only making 800 psi at the floor front and back. But would hold that pressure not bleed down. Line Lock would hold pressure. Was making 1100 before . 1.03" Mopar MC . Hurst Line lock acting as my T for the front lines. SS flex line to Wilwood Dynalites 4 piston 1.75" on the front. Adjustable prop valve in the rear line. Rear is 79-81 TA brackets and rotors and 2.5""metric" caliper on it. Can't find a leak anywhere.
This weekend it is down to 600 psi at the floor and by hand I could push the pedal 2" before any pressure is made. Took the lines off at the MC and plugged it and pedal barely can move 1/8" like a well bled MC. Still no leaks. RF wheel is pretty tight to turn by hand, a lot more than left. Rear seem to move OK but spinning rear end/trans would make it a little harder.
Any thoughts? Stuck piston in the Wilwood?1978 Black Trans Am 455 Edelbrock heads [email protected] through mufflers on pump gas
