Rear Brake Pad Change with Ista
If you put the rear brakes in Maintenance mode through ISTA, do you still need the special tool to compress the piston to fit new pads?

I used a Foxwell scanner to put them in maintenance mode. Should work the same as using ISTA. This moves them to the fully retracted position electronically, so you don't need to manually move them to the retracted position.

Yes, it will retract the parking brake but the brake piston still needs to be compressed to fit new pads like any other caliper.

Compressing is different than winding back the parking brake.
I compress pistons with a C-clamp from my tool box while the piston-facing pad is still in place. There's no need for single-tasking tools for this operation. I generally also open the bleeder to push fluid out at the caliper at this phase instead of back into the lines. This is usually where the nastiest fluid is anyways. Win/win. |

Guys, they are talking about the rear which has a motor and can't be just pushed back, it's threaded. To compress that I did not use ISTA but the appropriate torx bit and it worked just fine.

You need to use ISTA/Fox/whatever to wind back the p-brake AND something to compress out the fluid. My F10 rears were covered by extended service plan the first time so I'm coming up on my first F10 DIY rears job this fall. So, granted, my comments are based on my prep reading, not firsthand experience yet. |

Correct on needing BOTH, I was just referring to the parking brake however, based on my firsthand experience you do NOT need the software. I simply removed the motor, opened it up and it's reverse threaded and you can easily wind it back with the right sized torx IIRC. If you aren't comfortable with that, which I get, you can use software, I'm only saying it's fairly easy and straight forward to do. |
