i have new flexi hoses, new 3/4 bore master cylinder and fully rebuilt calipers, i bleed til theres no air then go to next wheel and abit of air bleeding til clear then back to first wheel and air again ?


the pedal almost hits the floor first pump then feels good after that until left for a few seconds then hits the floor again first pump ?


its like there a bit of air in there just trapped maybe ?

i can see no visual leaks anywhere ?


its only front brakes rears are blanked off for now, its only a single entry system on a kit car with no servo, so only running 2 short pipes to front wheels, really baffled by it the brakes are useable but shit tbh

im not to sure what to do ?

 

because you've blanked off the rears, the system should be pushing fluid to the rears first if int's as a normal conventional set up

reconnect the rears and see what happens as i think on the lift it's drawing air back in from somewher, even perhaps from inside the resivour

 

have you tried a vac bleader there the best thing since sliced bread, i have a old range rover and thats an arse to do its the only thing that will blead it,

if not fill the master cylinder to the top and leave one blead nipple open for a good few hours to let some fluid run through under gravity try on both sides just keep the res toped up.

 

theres only 1 outlet on the master cylinder, rears are just blanked on the t piece so wont affect it.
