Help: How to completely disassemble rear calipers with electronic parking brake?
I'm planning to upgrade my braking system to the larger European 550i spec brakes front and rear. I bought the rear calipers on ebay and plan to powdercoat and rebuild them before installing. However, I'm wondering if anyone has any insight into how to properly remove the electronic parking brake system on the caliper side. I've removed the plastic parking brake housing, but there is this metal disc underneath it, that's opposite the caliper piston.
If I were winging it, I'd pull the piston out first and expect that I could just push the parking brake mechanism out the other side once the piston is removed. However, knowing that almost nothing on BMWs is as simple as it seems, I thought it prudent to check with the community to see if anyone has done this before and can provide any tips. |

Hi
there are 2 bolts which you need to unscrew to remove electronic parking brake body unit from the caliper. on your second pic, you're touching bolt on one side with your fingers. You may need 2 wrenches for that. one to unscrew the bolt and another wrench to hold a nut which is under otherwise it would be spinning. I followed instructions from this link when i replaced my rear brake rotors/pads last month https://f10.5post.com/forums/showthr...ght=rear+brake It seems that you removed the cover of the electronic parking brake body unit Last edited by OrcaPod; 05-21-2019 at 09:55 AM.. |

In short, I need to get the caliper completely stripped down to the metal so that it can be sandblasted and powdercoated. Hopefully this is more clear. |

I did get around to doing this and my complete post can be found here: https://f10.5post.com/forums/showthread.php?t=1792113
However, in that post I didn't specify things to the level of detail that you're looking for. The short story is that there is nothing overly complicated behind that metal disc, so nothing to worry about. This video shows a slick way of disassembling that I wish I would have used (starting at 3:25): |
