Disk Brake Conversion

Post  bobafet1 on Tue Feb 10, 2015 12:28 am

Has anyone done this with parts from a donor vehicle? If so, can you please advise on compatibility. I have a 69 Elf and would like to upgrade my brake and suspension before going with a bigger motor.

Any info is appreciated.

I done it on my 64 Elf MK2. its a hard brake and could do with a vacuum assist but stops nice and square!

I've gone for a set of 7.5" Cooper S brakes on my Elf, but it's a long way off completion at the moment. I chose the 7.5" set up to maintain the 10" wheels. If you're happy with going to 12" wheels then a post 1984 8.4" Mini set up will do, these are more plentyful and cheaper second hand.

This is the Minispares conversion kit using their own bits, there is a genuine parts version too. most Mini specialists do the kit.

Can definitely agree that Cooper S 7.5" brakes work a whole lot better when fitted in conjunction with the Lockheed Vaccuum Servo unit.
This was the norm on the Cooper S Cars from (I think) 1964 1071S ; 1965 1275S ; 1968 970S.

It might be more appropriate to say that the S discs work easier with the servo than to say they work better. I prefer no servo.
At the same time as the front disc conversion is done, either change the rear drums to S drums or add a spacer.
It's also a good time to think about replacing old brake hoses.
And don't be surprised if the standard, 3.5" wheels don't clear the front calipers.
