Just fitted new front pads pedal dropped to floor changed master cylinder brakes rock hard  as soon as i switch on pedal drops to the floor again blead it in the right order and still the same any ideas

[TheBoy]

Did you clamp the flexihose when you pushed the caliper pistons back? If not, you *may* have inverted mastercylinder seals.


Failing that, still air in there. As longer as no air in abs pump, a simple bleed should get rid of any air. Air in abs pump is a tech2 job

[Brikhead]

How did you bleed the brakes and what was the 'correct' order?

Wonder if air entered abs 

[duval9]

if there is air in the abs how do i get it out

[tidla]

there is unions on top of the pump.. first thou i would use flex brake pipe clamps to try and suss which circuit has the air in.
if you need to and you know what your doing there is a way to activate the pump without kit.

Diagnostics equipment to continuously run the pump in 10s bursts to pump the air out. Pain.
