I’d like to start a discussion on the filling of an all new brake system on a build of mine.
The system consists of (4) Wilwood twin piston calipers, CPP master cylinder with combo valve and stock C10 pedal assembly.
I have confirmed that if I leave the brake light switch off of its mount that the pedal will stroke the mc piston far enough to bottom it out in the bore so bench bleeding should not be necessary.
My idea is to completely retract all 4 calipers and gravity fill all four corners till I get a good stream of fluid then attach an Oringed lexan mc lid with vacuum tap and pull a vacuum on the complete system from the lid with the hopes that any trapped air will migrate to the vacuum source.
My concern with this plan is that I’m not sure if the vacuum will shift the combo valve and block a port.
My goal in all this is to avoid at all cost having to remove bench bleed plugs and connect lines over top of an expensive paint job because for me it’s nearly impossible to not have fluid dripping before the lines are tight.
Do you think this is a solid plan?
I would really like to see how the mfg’s fill a brake system because I really doubt they are assembling with a wet bench bled master cylinder.
Ideas?
