DRAG RACING MASTER CYLINDER INSTALL
Still need to tweak the lines arround some to clean up the angles and get the lines a little bit more square to each other, and rotate the line lock some to "stack" the 3 lines going front to rear, but this is a rough install at this point. also, i reused the old tubing line nut on the porp valve or brake light switch for the one line that has 1/2x20 threads going in, and cut the tubing shorter and re-flared with the old line nut going out to the rear brakes from the prop valve. There may be other ways to do this, but this is how i did it. both m/c outlet holes are inverted 3/16 flare openings. just switch your line routing at the m/c. the front and rear fluid chambers are reversed due to the resovior having the larger chamber at the rear. but you'll have to fab up your own pedal pushrod and dust boot or order them from the above mentioned.

turn off and see if pedal moves up or down.Here's a DIY parts list for a drag race or off road racing power to manual brake conversion for the second gen camaros and probably a few others as well, using the same basic parts sold by strange and wilwood for about half the cost. Also will reperforme air tightness check B which is leave car on for 2 minute.
This is driving me crazy I have a race in less than a month and I have to get this thing fixed.ĮDIT: heading back out to check the check valve between engine and booster. Another note is when I adjusted the booster piston for the master cylinder the piston pulled out from the booster slightly but I think I got it back in its right place. Also I don't think its air in the system because I should be able to pump the brakes to get the pedal firm if it was air. Should I try a new booster? I bled the brakes multiple times using a power booster so I wouldn't wear out the master cylinder. So seems to me like it fails operational check b and possible air tight check a. I would say mine sinks practically to the floor.Ī) seems like to goes to the same spot each timeī) doesnt sink any after car is turned off. I dont know what the tsrm means by slightly going down. I started the brake booster checks.Ī) seems like it goes to the same spot everytime pedal gets firm but lowī) when car starts pedal sinks a bunch. No matter how many times I pump it when the car is running it sinks.
Took it out and the brake pedal sinks practically to the floor with little brake power. New master cylinder from driftmotion installed. Rock auto has a bunch of different brands but seeing how I already sunck 140 bucks on a crapping pep boys cylinder I would love some input on which brands people have used that worked.Īlso this couldn't be a stuck or sticking proportioning valve could it? The problem last go around only affected the front two wheels, and the car does not have ABS Also the rear piston on these failed master cylinders is impossible to get out of the bore which is what is leading me to believe the rear pistons is scuffing bad.ĭoes anyone know of a good source for master cylinders? My plan was to buy a new toyota cylinder and then heat wrap it using the DEI cool-tape but I need to find a good high quality cylinder first. I just called a toyota dealer and the Non-ABS master cylinders are not available anymore. The Oriely's cylinder leaked, and now the pep boys (new) cylinder has the same lockup issues. At this point I had to buy parts store master cylinders. All was well for a couple races then the same problem cropped up again. We replaced the then toyota master cylinder with a spare toyota one I had off a parts car. Clearly the master cylinder piston was sticking in the bore. This told me it wasnt a caliper sticking etc.

We were able to isolate the problem to the master cylinder because when I came to a stop with the brakes locked, we could crack the line from the master cylinder to the front brakes and the wheels would instantly go free, even when hot. Last year I had some issues with the brakes dragging and then the fronts in particular locking up after racing for a certain period of time. Well I have hit a road block so I need some help.
