Welcome along.

If you got air in the ABS module then you need a scan tool to bleed it properly.

With all bleed screws shut, does the pedal get hard after a few pumps on the brakes or no?

As Richard said you can bleed the abs pump with an obd.

yes after a few pumps the brake gets hard for about 10 seconds then straight to floor again, interesting theres no abs light on the dash either, makes me think i probs didnt need to replace the abs pump afterall. i could be worng but someone told me if i didnt leave the ignition on during the changing of the caliper then it would have messed the system up.

I do not know if it applies to your car but often if the pads/caliper are replaced on the axle with the handbrake, you should not use the handbrake until the pedal has been used to push the pistons back out.

I replaced a front caliper on our C5 (which includes the handbrake) and whilst I did not think any air got into the abs system I could not bleed it well enough to get a good pedal. I took it to the dealer to do it with a diagnostic tool, charged over £100 since it included the diagnostic but afterwards the brakes were a lot better. They tried first without the diagnostic tool but that did not made any difference.

Your advice to leave the ignition on whilst replacing a caliper does not sound right, was it a Citroen expert ?

local back street garage told me, which is where the car still is, they said they have tried everyting and cant work out why the pedal isnt holding.

lastest news they have given me it back they say they cant do anything. is there anyone on here warrington/liverpool based who can help
