Brake pedal returns way to slow ,when engine is on . When off its hard after 1" or so of travel and returns fine.
Bench bleed MC and system A dozen times
When I bleed the MC it was installed on firewall and pedal goes deep as it suppose too and returns perfect no binding.
When I put pressure on pedal while engine off and than turn it on pedal goes lower , seems normal...
Booster is holding vaccum
At driveway speeds it seem to brake good
Pedal travels about 3" when pressed . Normal ?
Everything seems ok but the pedal return is terribally slow.
My setup consists of DSE unit willwood proportion valve , 100% SS hardlines except hose from body to rear end . 14" willwoods up front 13" on rear .
Had pedal to booster rod at disk / drum hole but now drilled new hole a bit lower for optimum line of travel ,
Slotted / opened up hole at firewall plenty to eliminate any binding.
I pulled out unit today plugged exits coming out of proportion valve , removed boot from booster
Plugged up vacuum line at engine and still seems to return to slow but hard to judge because I don't get a lot travel do to plugged lines
Here's a video clip ..
