KAD Brakes

[steve]

Thanks everyone for all the advice!

[quote="WNX700H"]Since my line of work is brake system design , I would recommendyou stick with standard S calipers , I had Minisport 4 pots on a car I bought and the stiffness of the aluminium caliper is significantly less than a std cast iron S caliper. Much firmer progressive pedal with the standard caliper.
I would have thought that a high grade aluminium billet would have equal stifness to a standard cast iron caliper?

999ORX - No I'm not planning on using a booster at this stage

I have emailed MiniSport about their 7.5" 4 Pot Alloy callipers to ask if they have ever fitted them with 10" steel rims. If they don't look like they are going to fit I will prob end up with the standard S callipers, as I like the steel rims too much and Speedwell wheels cost moonbeams.

Cheers again for all the help!

my mates run minisports 4 pots never have an issue at all if anything feel much better than standard S capilers

That's assuming his S calipers were working properly and the discs were in good condition, which may not have been the case. Lots of the historic racers on here are using standard calipers.

System was working fine ran Grooved discs and green stuff but just down to messing around on the track use to lose braking a little bit so he went 4 pots and braking distance has shortened a bit too

I'm going to run 4 pots to be fair I like to feel whats going on. drums all round scare me to death.

But all IMO

If you just want disc brakes in steel rims then just go for standard S callipers. They work fine with or with out a servo, the mighty minis use them and they cope

But if you are wanting alloy callipers go for the mini sport or mini spares ones, or KAD ones but there set at a higher price but still a very good calliper

I know rich was saying that the mini spares alloy 4 pot callipers had more room inside a rosepetal rim than standard S callipers

I have found on my S callipers inside my MS rosepetals it hits the weights very slightly so a little filling need doing to the calliper but I would think a steel rim would have more room.

My 2 cents worth, brakes on my 1978 (UK Mk3 body) 1100 Delux (now 1380)

I had bought a set of Mini Sport 4 pots of a dude on the Turbo Mini forum, and i must admit, they looked freeking lovely.....

See....





Then i was told that they dont have dust seals, (not sure if its a fact though) and living in Africa, where in Winter it is dry and dusty, i thought it would be better to have a caliper with dust seals, so these were sold on to a dude that used them on his race car. i then bought these Mini Spares calipers, they do have dust seals.






Both sets of brakes were on Cooper S disks, and fitted perfectly under both my Mini Spares 6x10 Minilifes and the 6.5x10 Force Racing wheels.

Using a Dual master, running direct with no bulkhead valve, using smaller 15mm rear slaves, and brakes are awesome with no servo.
