Decided to refurb and clean up the calipers on my Mondeo ST (07 plate). Took calipers off, cleaned, painted, renewed all seals, put calipers back on. Repeated on all four corners then bled the system - no brakes. Bled several more times - still no brakes.

Eventually got to a point where there were some breaks but after a point the pedal lost all pressure and fell away. This lead me to suspect there was a problem with the master cylinder. Replaced master cylinder - bled system - no brakes.

Spoke to a friend who works for Ford - suggested it mightneed an ABS serv ice bleed. Phoned a local garage who said they could do it - turns out the couldn't so they sent it to an Arnold Clark Ford garage....

They said rear calipers were at fault - replaced calipers - still no brakes. Now suspect problem with ABS unit. No fault lights on dash board.

Anyone have any thought son what it could be? Can an ABS unit be refurbished or is it a case of shelling out for a new one? This has been dragged out for over a week now and it'sdriving me round the bend should have been so simple!

Any advice appreciated.
