Rear Wheel Cylinders

[MiniGT5]

OK Guys,

Whats the deal with all these rear wheel cylinders. I have just been looking on minispares and there are so many to choose from. The choices are: -

5/8" used from 1959-1967
3/4" used on all later models
9/16" used from 1959-1967

What ones are correct for my pickup with drums all round?

Also what ones do I need when I fit my cooper S discs and spaced drums.

Cheers
Neil

you got to find the right one applicable to the single line system using disc brakes .
gwc 1101 fits single line 'S' models .

all mk 1 2 and 3 s models ( disc braked models ) used a brake regulator valve ( at rear subframe ) that matched the 5/8 wheel cylinder bore .

non s mk3 models to 78 had a 3/4 inch cylinder and a differant poundage weaker spring in the regulator .

if it helps , minispares do a adjustable regulator ms72

i know you have a pick up but you dont use it as such so for your application treat what you want for a saloon model.

got single line system and 7.9 (8.4 ) discs on mk1 , but cant remember which valve or cylinders i used . 5 years ago now.

i am running single line system with cooper S brakes, i did not know what size wheel cylinders i need but i knew i need a brake regulator some where???

after chatting to andy on the ML website he said to run 19mm- 3/4" wheel cylinders and have an adjustable brake regulator, so you can set it how you want and get the most from your system, but get it set up at a garage on a brake machine

this is what i bought

i am having to put it in the line which runs from the front to the back,
i am mounting in on the left hand side bulk head just below the pedel box hole then running the brake lines inside to the back,
its not on a place where someone can kick it and not seen so easy, and also easy for the garage to adjust when they set the brake pressure to the rear correct, just means making up your own brake lines

but if you want to keep it original go with daves advice as its tried and tested

I looked at Deans regulator on sunday .
I will be using the 3/4 cylinders and same regulator on my current project for 2010.

Looks like I will probably go the same route.
