32 Ford roadster, 4-wheel Wilwoods, dual chamber MC. Have replaced MC, residual valves and checked all connections. The problem is getting all the air out of the system. Have tried pumping the pedal and using a vacuum pump. The calipers have two bleeders each pointing stright up. Using the vacuum method, 6 of the eight are indicating no air bubbles, the other two (not on the same caliper or end of the car) are still showing air bubbles. I pumped two 12oz cans of fluid through the system tonight and still have the bubbles.



Is there a better method or do I keep vacuuming until it clears up?

Did you bench bleed the MC before installing it?

After installing the Bench Blead M/C, start at the bleeder the greatest distance away first, open the bleeded with the pedal up, press the pedal down slowly and close the bleeder and release the pedal, repeat it until you get no air, move to the next closest and repeat...on and on until their all done, Make SURE the M/C never runs dry. after that is complete, Start over with the farthest one and repeat it with a pumped up and pressurize pedal this time.

That should take care of it, If that dont work check for leaks, air will be sucked in just as easy as fluid will leak out.

Sounds to me like you are sucking air somewhere. Put full pressure on the system with the brake pedal and see if you can find a leak (or two). I have also found that the bleeder will suck air around it and give this indication.

your sucking air around the threads of the bleeders with a vac pump. never pump a brake pedal. this makes small bubbles from big bubbles. if you airate the fluid it has to come out as it takes for ever for it to collect. if we airated the fluid on a bird we had to powerflush the intire hyd system, not to mention the ass eating we got. good luck

Bleed the master cylinder in a vice. Do not keep pumping brakes furiously when bleeding, you will cause more problems.

We use a combination. We bench bleed and then check with one in the car and one on the bleeder. Has worked for years for us. I am usually the person in the car. :-)

is the m/c mounted under the vehicle, or on the firewall? Gravity bleed works, just time consuming.

I had that problem once, drove me crazy, I did every thing right about the bleeding.....but I had both caliber off the fron at the same time----and I switched them around when I put them on. This caused the bleeder to be slighly lower than the top of the caliber, thus the air never got out of the top. Onced switched right they bleed perfectly!!!!!!!!!!

AS SHINE SAID YOUR SUCKING AIR IN AROUND THE THREADS ON BLEEDER SCREWS USING VACUUM BLEEDER YOU NEED TO WRAP TEFLON TAPE ON THREADS AND THAT SHOULD HELP SEAL IT.

before you loosen the bleeder, place bearing grease around the threads at the backing plate. then loosen bleeder and vaccuum bleed. This will stop the air from coming in around the screw. Make sure the wheels are hanging lower than the M/C while being bled, and that you don't have 'loops' in the brake lines. works for me hope it helps you
