hi guys,

 

My mini is a 1978 mini and in that year they fitted what is possibly the worst braking system british leyland ever fitted to a car and I've had nothing but problems for the past 2 years.

 

Enough is enough and I've taken it off the road to re-do the whole system from front to back and I'm wondering what the best system is for a 7.5inch disk set up?

 

I've already purchased these from minisport at the weekend for the rear link, its the 3/4 bore brake cylinders instead of the current 1/2 inch bore as these don't seize up anywhere as easily.

 

I intend to get the minisport conversion kit with the 4-pot callipers and mintex pads for the front along with steel braided pipes at each wheel.

 

Its at this point I get stuck as I know there were various set-ups installed in terms of master cylinders and dual line and single line braking and I don't know which type of system is the best one to go with and I don't know what type of brake bias valve I should get to reduce the pressure for the rear wheels etc etc.

 

so if anyone can offer advice then please do 

 

thanks, Adam

 

also just thought, I would prefer to not get a servo as my mini will be getting modified to a point and to keep some of its history I will be changing it back to left hand drive in a few years when I can get classic insurance

I just replaced my mates drum braked 78 mini with Mini Spares 7.5 cooper S setup on the front, and alloy drums at the rear. Also replaced the rear cylinders, all the lines and hoses, the only part thats the same is the single line master cylinder.

 

Its a 998cc with a stage one and the brakes are now more than effecient. I have the same setup on my own car, but using front rear split with a servo. They are pretty much the same in terms of braking power and stopping distance (my car is a 1293 s/c using fuel injection)

 

The 4-pots might grip that bit better than the single piston AP "s" caliper, never experienced them before.

You're really obliged to keep a dual system if it already has one. A front rear split is the most effective. Trying to stop a Mini with one front & one rear brake is littleetter than no brakes at all, and you'll have the option of using the yellow band master. Either brake valve will work, Willwood also do some nice adustable ones.

@maccers, your mates mini must have been a very early 78 mini if it had a single line brake master cylinder as mini has a dual line brake master cylinder and the way they compensated for having no brake reducer valve is they fitted smaller bore rear brake cylinders with 1/2inch bore which I haven't even been able to source anywhere in the UK at least

 

so a decent system for me to fit would be a dual line system with a yellow tag master cylinder and I quite like the idea of the reducer being adjustable so a wilwood one would be a good idea?

 

thanks, Adam
