I am just about finished with my 31 Roadster. I went to bleed my clutch slave cylinder and found that when all is the air is gone I can hardly push in the clutch. I am using a 1961 Chevy dual master cyl and an unknown slave that fit my bell housing. Can anybody tell me what is wrong. Also I am using a set of old Ansen pedals that fit nicely.
I would venture to guess that the Dual master cylinder is not generating enough pressure easily (due to a large piston diameter). I would switch to a single chamber master cylinder design for clutches, not brakes. Good Luck
First you need to verify that you can operate the clutch manually without the slave cylinder. Disconnect the slave from the arm, and try amd manually operate the pressure plate back/ clutch arm and forth.
I'm trying to picture how you've hooked a brake m/c to a clutch slave..... Get a clutch m/c, they don't have internal valves, are correct volume, etc and are made for the purpose. And, you will need to know what that "unknown" slave is for.
I guess I need to explain that this master cyl is designed to do both Brakes and Clutch. The resivour is a common supply for the fluid, but each side works independently.
Ron The key is finding the right slave to go with this. The orig one mounts on the starter side of the block. Any Ideas.
Check mechanical items first: Can the pedal move the master fully? Does the fork move the throwout bearing properly? Does the master 'move' physically, when you press either pedal under pressure? If all is well, you need a larger bore slave cylinder. Cosmo
Back in the day we swapped the original slave cylinder to the Left with a fabricated bracket fastened with bell housing mounting bolts. Good luck.
Disconnect the slave from the transmission arm. Check each carefully to insure they operate and are not binding against each other. Check to make sure you have replumbed it correctly with the brakes to the brake side & clutch to the clutch side. Good luck
master was used as I said. Go to Napa and get a new one. Switch back to the bellhousing that was on the car when you got it, and all will be good.... Best wishes, Gary
A bunch of useless replys from people who have never used this system ! 1 Did you swap the internals of the M/c side to side? 2 The pedal set has not been modifyed with shorter arms ? 3 Measure the bore of the slave needs to be 1&1/16 to work properly with this M/C. 4 If the above check out I would then check out the T/O fork for free movment with a big lever/prybar etc. I'm running the same setup with a H/D 10.4 cover and have a nice easy pedel .
Been using this setup out of 1961 econoline Ford since 1968--works great! I think your problem is in the slave cyl. match up with master cyl.bore.
I had the same setup on my Tbucket - switch guts - make sure the slave is the correct size - and be sure the fluid lines are sized right. Worked great!!
Like has been said - assuming you've got the brake residual in the correct bore for your pedal setup - you have two options: keep the slave you have and sleeve down the master clutch bore to work with that slave, or find a slave that will work with the master bore diameter that you have.
Just a quick question, maybe a dumb one. On the master cyl. the brake is labeled on the left hand bore & clutch on the right hand bore. When using the Ansen pedals the clutch actuates the left bore & the brake the right bore. Do you have to take the cyliders apart and swap the internals from one side to the other side? Thanks Duane
