Post subject:  Brake cylinders rear

Hey one of mine is leaking I am about 99% sure I have Cooper AP 7.5" discs. Which rear cylinders should I be using. From what I remember when I did this last there are 3/4" 5/8" cylinders. Spoke to someone this morning at Mspares & he mentioned 1/16" cylinders.

Which ones guys?

For a disc brake front end you need 5/8" rear cylinders. 3/4" rear cylinders are for cars with drum brake front ends.

1/16" cylinders seem a bit small. I would think you may have misheard the measurement.

There is some usefull information on the Minispares UK website.
Here is a brief cut and paste which may assist?
-------------------------------------------------------------------------------------------------------
As a guide to start with, working suggestions I have used with reasonable success can be generally channeled into a few groups -

*Discs with 4-pots and latest built-in servo and 7.5" discs with S-type servo, use GWC1131 -- 0.5625"(14.29mm) .

*8.4" discs with or without servo, use GWC1126 -- 0.500"(12.7mm).

*7.5" discs no servo use GWC1129 -- 0.6875"(17.46mm) .

it's a working start.

TK im in sydney & karkraft is just down the road but I'll let u know. Thanks

Then I'm after the smaller 5/8" ones allowing more pressure to the Cooper discs I have.
