when i did mine i changed the calipers for a set i had reserviced with new seals and pistons. my worry was that as i work on my own i would not be able to bleed all the air out of the new empty callipers. i used the gravity bleed method and it worked well. once the hose was connected to the calliper first and tightened the rest was easy at the union end. once connected and tightened top up the reservoir connect your bleed pipe/container and slacken the bleedvalve ... and wait. as long as the reservoir is topped up it should bleed itself. mine did as with a friend to help a couple of days later we did a full bleed and did not see any air bubbles escape. kept an eye on the unions and fluid level for a few days after and all was well. well worth doing and gives peace of mind...

I've found the spanners. They look quite excellent! As for bleeding, I have a one man bleed kit which I haven't used yet. I'll be working with my mate so if it doesn't work we will do it the old fashioned way.

Thanks everyone for all the really helpful answers. Apologies that I've not been back before now to say thanks, it's a case of life with a full-time job, pandemic and toddler to look after getting in the way!
I've heeded the info given by everyone and have ordered a calliper service kit and two wear sensors which I'll fit tomorrow. I've rebuilt my MG Maestro callipers in the past and looked up a few videos in YouTube about the BMW ones - turns out it's all exactly the same technology so I think it'll be easy enough to get the job done. I'm going to take my time and clean all the calliper carriers up (front and back) and also get the replacement sensors fitted so that everything works as it should. It was interesting to see the post, saying that this is a lack of maintenance, I agree that this sort of thing should be attended to as part of the service schedule, but I think this car is an extreme of age and low mileage, with a bit of neglect thrown in as well - hopefully I can get on top of that and make it a good example of its breed! I'll let you know how I get on. |

Oh No - I've had the calliper off and replaced the piston and seals, also taken the pad carrier off, filed it free of debris and refitted it - the pads definitely move freely. The system is free of air and seems to work effectively, however, it's as if once the brakes are applied, the piston on that side sticks until you manually push it back.
I'm scratching my head! I don't think the pads were sticking before but can't be sure - I tried the old pads in the cleaned carrier and they also still stick now. What a nightmare! |

I spent a significant amount of this afternoon strippijg it down and putting it all back together so it's a little frustrating that it still doesn't work. Cars, eh?! |

how about the pin rubbers inside the calliper. you can change these easily. have you cleaned and lubricated the pins as well ? the rubbers get worn and chewed up after a while. without the pads in the calliper you should be able to pull and push the calliper in and out smoothly without much effort. if all this is good then check your flexi hose is not retaining pressure . you can do this by slackening the bleed nipple after you have pumped the brake pedal. a spurt of fluid would probably identify this as being the culprit. ideal time to renew them anyway ....

Thanks ever so much - I really appreciate the advice. I'll do that check tomorrow and see if that's it.
TBH, if it's not that then I think it could be an issue with the ABS pump, so I hope it is!! As you say, it's maybe not a bad idea to renew them anyway - everything else will be new or re-conditioned. I'll report back.... |
