No nipples on the ABS unit. i presume Thats why you can do it electronically....

Just waiting for the master to be replaced along with the servo seal

Master cylinder improved it but didnt fully get rid of it. Found the brakes would not bind while the car was running with the vac pump pipe not connected, but as soon as it was they would just start to push the pistons out and make them bind. This is while the car is jacked up and not even moving and no brake being applied on the pedal. So i suspect servo. Another mechanic has looked at it also and is replacing the servo on it tomorrow. ( I dont have time) so will update then. Fingers crossed

i have replaced a few servo units for the same issue, you do not need to bleed/run the ABS system via diagnostic software unless you have replaced the ABS unit itself.
Let us know how you get on, ill rack my brain as im sure we had a leon with a similar fault that wasn't the servo unit, but i cannot for the life of me remember what we did to rectify it!
