Some minis had a 2 bolt caliper, you want the 1 bolt calipers to get the bigger piston. So you may get a 87 caliper and bracket with a 84-85 rotor. All turbo minis had the right caliper and pad, you could buy the pads for the 89 mini and rotors for an 84. Its been a long time since I did the 4 lug bigger brakes lol.
get any mini van master if you want, it makes the brakes a little quiker reacting and less likely to lock.
I don't think the 13s fit, I believe you need a 14" wheel at least. Reliant K cars had a vented front disk that was smaller diameter and will work with 13" wheels and cool better. I have them on my wagon. At the very least you want the vented front rotors, but you may not need a big mini setup. Just a brake that doesn't fade and has more power.
If I was looking for the junk yard build up for my L body. I would look for a turbo Daytona in a yard and get the 15" aluminum wheels and rear brakes. Then buy the matching 4 or 5 lug mini van front brakes. Then run a cheap 195 50 15 tire. The early Daytonas ran 4 lug, so you don't have to change your front bearings. If your keeping the rear drums and not going to disk, then the turbo Daytona front brakes are big enough. Then you get it all from one car. 84 Turbo Z has everything you need really, including the wheels.
great thanks!
little more clarity
the calipers and caliper mounts can be off any 84-90 mini, be it 4 or 5 lug? and order 84 4 lug mini rotors and pads
do the master and rears at a later date (just a crap drive to work for the gas mileage car at the moment)
will i have any clearance issues with the calipers? can i still use the stock 13" wheels and tires? or do i have to use a bigger wheel?
