Brakes - Fitting Discs and Required Ancillaries

What you actually need for the disc/drum conversion is pretty straightforward. Disconnect the steering arms, top and bottom swivel-pins, CV joint, and flexible brake pipes at the subframe - that’s it. There are, however, a number of ancillaries to consider.

Basics

Basics Fitting discs designed for the Mini is easy enough. Just make sure you use CV gaiters for the disc-brake set-up - these have a different bellows shape to stop the gaiter rubbing the inside of the hub. The drum type will rub, then split, shedding grease all over the place. Moly grease is mighty mucky stuff to deal with and doesn't assist braking at all! A tip for racers - to stop the gaiters over-expanding when getting very hot and imitating the aforementioned, put either a decent sized split pin or (my favorite) a piece of very small bore pipe - as in the type supplied with WD40 aerosols, etc. - under the retaining strap on the drive shaft. This allows air to escape and return,

Fitting instructions for Remote Vacuum Servo Units Types 6 and 7

General fitting instructions

To ensure correct installation of the AP Braking remote vacuum servo unit, thoroughly read and adhere to the fitting instructions prior to carrying out any work on the vehicle. Introduction The vacuum servo unit is incorporated into the hydraulic braking system, remote from the master cylinder, as an intermediate stage operating between the master cylinder and the brake assemblies. The two main parts of the servo unit consist of the vacuum servo mechanism and the hydraulic slave cylinder assembly.

These component parts are bolted together so that the slave cylinder piston is in line with, and is operated by, the servo push rod. A plastic no-return valve is fitted into the vacuum shell and an integral air cleaner is incorporated to prevent foreign matter entering the air control valve chamber. The servo unit is designed to give no assistance with very light brake application. In the absence of servo assistance due to loss of vacuum, an unres...

Historical Article - Nov 1992 - History in the making

Having built one Cooper ‘S’ for Timo Makinen to use in Historic Rallying, in which he won two International Rallies, I decided to build another one with more power and less weight than the previous one.

One lesson I learnt the hard way building the first car, was that a reliable source of new parts with in-built quality, especially where obsolete parts were being remanufactured, was essential. Mini Spares of London...
