Bleading Brakes. Help !
 

Well I have just finished all the lines brand new everything. I am using dot 5 fluid.

Anyway I epoxy primed and painted my MC then installed it. Filled it up and opened the bleader screws. The front came out in a few minutes. So I am ready for a helper to push the pedal out while I open the bleader screw and close it before they let there foot up. But the rear will not run a hour later and still nothing. Did I have to bench blead the MC ?

Any way to get around this ?


Thanks for any tips.

Yes you always have to bench bleed the MC you can do it when its installed it just requires more pumping of the pedle

Try cracking open the line coming out of the m/c. Usually you can get fluid to flow there, if not do your bench bleed with that fitting. Have your helper push the pedal down, then open the fitting to release the air.

Since everthing is epoxied, find line plugs for the openings of the mc and just keep pumping the pedal until no bubbles come from the ports inside the mc (at the bottom of the resevoirs). The mc is now bled. I've had good success with gravity bleeding at the wheel cyl. Open them and let drip until a steady drip is seen. The plugs are available at auto parts stores.
