Mini One, Cooper & S, Generation 1 & 2 - 2001 to 2014 - Rear Brake Caliper Renovation & Rebuild

Hello everyone and welcome to the channel and welcome to another video with the little Mini Cooper R50.
In this video, I will be removing the rear brake calipers from the car and carrying out a refurbishment. This will involve a complete strip of the entire assembly, a thorough clean and then reassembly using brand new seals and pistons. I'll even be giving the caliper castings an attractive coat of paint for that fresh out of the box look.
The rear calipers on this car were noted as having a very slight binding action on the last MOT and as such are in need of an overhaul to bring them back up to full working order.
I have linked the rebuild kit below that I used in the video.

Please double check your piston size before purchasing or ask the vendor to check using your registration number as some models do have larger diameter pistons fitted.
For those that do not wish to rebuild the calipers but would rather replace the whole unit, a pair of rear calipers can be found at a very reasonable price at the link below.

BMW also recommends that the anti-rattle springs on the calipers should be replaced if over 2 years old, linked below

Man, you're doing a great job.👌

[@KevsShed]

Thanks man! Means a lot! 👍🏻

[@londoncentral]

Only recently found your channel keV 😉 Kev's shed. I have a Mini cooper s R52. Really enjoyed and learnt a lot. If I wasn't an OAP I'd love to buy you an electric wrench 😉🤣👍

Good video Sir. I'm going to buy a refurb kit and tackle one on my R56.
Ultrasonic cleaner looks the dogs.

Awesome video Kev. Also busy rebuilding my rear callipers on a R53. Got everything done but after struggling for about 1hr20m to fit the spring back into the piston, i decided it was time to go to youtube for advice. Took me about three hours to find this video which relates to my calliper. Horrified when you did not demonstrate how to get the damn spring seated. Please if you have a moment, would really appreciate a short explanation of how to succeed.

[@scubaluxcreative2484]

Hello mate
Did you succeed wirh spring. Im about to give up. 😫

[@user-ts2kx3ns4t]

I'm in the same boat. There must be a knack or a tool.

[@anthonydeleijer2231]

Any ideas on getting that spring in? Kev even a quick walk through of the way you got in would be amazing

[@user-ts2kx3ns4t]

Great video - Here's the question though ! How to get the spring back into the piston. 2hrs now - Does the answer involve the ghost of Paul Daniels ?

[@user-cu2bz7kh9v]

Hi Kev what size is your altrasonic washer please as thinking of getting one many thanks Bill

[@KevsShed]

I think it was 15 litre from memory, I think I linked it in the video description 👍🏻

[@scubaluxcreative2484]

Is there a trick to putting spring in. Would of helped to show the 30secs.

[@skylined5534]

Found just pushing down progressively with something like a flat blade screwdriver until you can make it clip in under the lip at top works. Doesn't actually take a lot of force.

[@jameshay469]

That ultrasonic bath looks awesome. Do you put just normal tap water in it?

[@KevsShed]

I used deionised water and ultrasonic cleaner solution mate, I’ll find you a link to the solution if you like 👍🏻

[@KevsShed]

This is the cleaning solution that I use bud. ebay.us/TvPxHD

[@carlmock4575]

I'm interested in how you installed and seated the internal piston spring. Bench vise and lots of cursing?

[@KevsShed]

As it happened, it went in really easily! I wish I had video’d it now!

[@carlmock4575]

@@KevsShed Thanks for the reply but I'm interested in exactly what you used to seat the spring since it's larger than the piston opening. I'm struggling with seating mine.

[@user-ts2kx3ns4t]

im stuck - thinking of making something like a mini piston ring compressor tool.

[@mlarsen77]

Youre lucky its not a clubman. the 2013 clubman outer boot doesn't stretch over the piston hole on the caliper.... it has to fit into a groove on the caliper making it difficult to fit once the piston is already screwed in. Cant find anyone thats done the rear with this different boot style.

[@skylined5534]

I've come across those before. Pain in the assss.
Fit boot first as you say (making sure it's fully seated in the groove) then fit piston and use a healthy smear of red rubber grease to ease things together and prevent the piston pulling the seal baxk out.
