Thread: Can't bleed

Tweet

Anybody ever had a residual valve go bad (willwood) front disc. I can't get my 32 bled it appears that the fluid runs back to master when you let off on the pedal. It is below the discs and I have a tandem master cylinder. Thanx in advance.

Yes, they can go bad, and some are killed by Dot 5 brake fluid. We had to look for ones that were Dot 5 approved. Not saying that is your problem, but they can go bad internally. You don't have it installed backwards, do you?

Yes i've had new one's that don't work.

I replaced the single with a tandem, the brakes worked before with the same residual valve, but I notice after pumping the pedal the fluid rushes back into the mc.
