hi all I just fitted two new rear brake calipers and then bled them up all four wheels but no mater how much I bled them the pedal will not go hard so what do you think thanks

Stupid question but did you check the brake fluid level, and replace and tighten the brake fluid filler cap? Its surprisingly easy to forget, especially if you only loosened it and didn't fully remove it.

Oh dear, this doesnt sound good mate.

 

What method of bleeding did you use? pedal or with a pressure or vacuum bleeder?

 

I take it that there is no air coming from any of the bleed points?

 

Sounds to me like you may have damaged or flipped the seals in the master cylinder

Is the pedal just pushing to the floor with little resistance?

it builds some pressure then fall to the foor
if I pump the pedal it make a funny sound in the engine bay sound like servo
pushing air in to the top of the engine

what happens when you pump it up with the engine off? does it go solid?

in that case you either have a fluid leak somewhere, or as has been suggested, the master cyl seals have been flipped,

no leaks so it looks like a new master I let you all no the out come

if pedal gets solid then slowly sinks, one way of checking for air is someone to pump pedal and then you clamp hose off one wheel at time, this will trap air between clamp and caliper...i pedal stops sinking with one of hoses clamped then its air.

 

but does sound like a master problem...what was pedal like before calipers
