after changing my faulty caliper and bleeding the system twice, if you start the engine and press the press they go hard but if you keep your foot on the pedal it slowly over 10-15 secs sinks to near the floor
is there something else to bleed as well as the brakes or any ideas whats up?
does sound like a pump running somewhere near the master cylinder too, is this the abs pump?
cheers

My guess is the master cylinder seals are letting by, if the pedal goes hard then sinks its not air in the system, it would still be soft.
ABS pump would not kick in unless you were moving.

Re: brake pedal sinking c5 hdi
Is the pump a sounds a of small running motor over towards the n/s strut top? I have that one mine, though i only hear it when ive turned the car off and got out. Its quiet but easily heard in the garage. Seems to stay running for a few minutes after stopping the car. Anyone know what that is?sportingfiat wrote: does sound like a pump running somewhere near the master cylinder too, is this the abs pump?
