Some will tell you to open the bleed nipple when pushing the piston back, I have never found the need and certainly never flipped the master cylinder rubbers. Thinking on this, if it were a possibility then why does the rubber not flip when the brake peddle is pressed. That it does not indicates to me it will not. Just make sure there is room in the fluid resevour for the displaced fluid. The official manual method is to remove the motors, they are held by 2 small Torx set screws, often siezed and the Torx head strips when you try to remove them. I have VIDA dice and there is a program in there to back the EPB off, I failed to make it work and wanted the job done so reverted to the pp9 battery method. Paul. |

Thanks Paul. That sounds less bother than removing the motor etc. which is the method I have viewed. Just to be sure, that is done before removing anything else ?

Removing the motor, if you want to go that route, is easier after loosening the caliper. Otherwise the screws are difficult to access.
I always remove the motor, each time I maintain the brakes. And that I do each time I switch between summer and winter tires. Thus I never have any problem getting the screws out. Grease is your friend. Controlling it electrically sounds easy, but my experience is that these plastic connectors tend to get brittle over time. I prefer handling the motor, in spite of being in the electrical profession myself... Rotating the little jack in there, the one the motor otherwise rotates, is best done with an XZN 8 key. But everything that fits will turn the jack, as it rotates freely. |

front brakes/rear brakes
i just did the front brakes on my ex police model with the huge brakes
i removed the caliper carrier bolts,pinged out the pads and the sliding carrier cleaned it all up and re-assembled worth noting the police[last ones to do my brakes] broke off the metal spring clip at the rear of the outer pad to make it easier to fit-its not going anywhere anyway in reality so i can see why they did it I bought pattern xc90 pads for just over £8 off the web-from germany-as the car is effectively fitted with xc90 front brakes.... rears i used delphi software for the rears to retract the motors,cleaned up the brakes,pushed back pistons with a normal caliper spreader,regreased the slides and rebuilt with new bolts-pads about £13 |

While I only do it when nessesary I have not found a problem removing the connector, useing apropiate care of course, on my 10 year old car. I appreciate the danger of the plastic becoming brittle over time but would rather it break when at home and the tools are out than leave me stranded at the road side. Paul. |

So when daughter is able leave the car with me for long enough I’ll first try to remove the motors. Dealer alleged that all brake pads had been renewed prior to purchase two years ago but suspect they used the relevant kit to wind back the motors. At service in February ( 26,000 miles later ) there was a comment that rear brake pads would need renewing soon.

failing that i would wind back the motor with a battery connected. if you bust the motor casing etc it would be fairly costly to rectify |

Fortunately for me the programme to withdraw the pads worked. I have found as clever and wonderful as dice is, its only as good as the bloke pushing the keys on the keyboard, and I ALWAYS feel intrepidation and a great sense of unease when ever I plug in the OBI ONE into the car socket. To me its very much Voodoo, Black Magic and Witchcraft. Cheers Bob |
