I replaced my brake master cylinder with a new Raybesto unit as well as a new proportioning valve (OEM). My problem is I will get air pockets 5 min into driving, pedal sinks momentarily and then brake feel is back to normal
While bleeding brakes, once i crack a caliper open, air bubbles do not come out till about 10 seconds later. -Booster Operating check OK -Booster Air Tightness check – engine off OK -Booster Air Tightness underload OK -No Leaks at Banjo Bolts -Soft Lines OK -No rust between shims and pads -Caliper Pistons Seals not torn or leaking -Caliper Pistons move freely when pressed inward with bleeder valve open -------------------- For Sale Items:
