To take off my caliper bracket I needed an E18 external torx socket. 13 mm was for the two slides and 17mm was for the lug nuts.
There was conflicting information on this but I confirmed it today…YOU DO NOT NEED SOFTWARE TO PERFORM THIS JOB.
Using a pair of pliers you can push and twist the piston back in without putting the EPB in “service mode”. It will rotate clockwise right back into the boot. The big difference is, and where people mess up, if you don’t activate the EPB **first** once the jobs done the car will throw a bunch of codes. You need to make sure it’s deactivated during the performance of the task and once complete you need to activate it BEFORE YOU PRESS THE BRAKE PEDALS so it can find where its new normal is.
I had one half day to do this and I couldn’t wait for my hardware to come in to use bimmerlink so i went for it with some conflicting information. Thankfully you do not need to use the service mode for the vehicle.
There’s videos floating around where people manually drive out the EPB by removing it and using a T45 torx to unwind it and then use your piston compressing tool to compress it (not turn it). Using the pliers does the same thing, it compresses and unwinds the EPB at the same time by pressing in and turning clockwise.
Just to clarify, you dont need to use bimmerlink to put it in service mode, all you have to do is turn off the EPB then jack up the vehicle and when you get the caliper off, using a pair of pliers you can push and twist the piston. Once that is done and you install the new pads and finish reinstalling everything, you go back in the car and switch on the EPB before touching your foot on the brake. Once that is done you can turn the vehicle on?
