Rear brake caliper - does it always take forever to bleed?!? '76 750F
« on: April 08, 2011, 11:45:50 AM »
So I'm starting to think I may have a leak somewhere? I bled about 3/4 can of fluid through it last night and there are still all these little bubbles coming out. Is that normal? I dont think I'm leaking fluid anywhere so I don't think that's why my brake is still spongey.. Any advice?

What is your bleeding method?  Suction or pressure?

I had a speed bleeder installed, so I'm just opening that up and pumping using the brake pedal.

I never used a speed bleeder.  So, I don' know about that.

I do know that air bubbles will rise to the surface of a fluid inside a vessel.  So, that is where you need to let it escape the system.
Is your speed bleeder located at the high point and can air bubbles reach that point by rising?
