With up to 250bhp/tonne to play with, good brakes are an essential part of a modified vehicle. Ideally this would mean 280 or 300mm front discs with a rear disc conversion.
But so far my budget hasn't been able to stretch to this, so i have a set of old iron AP 4-pot calipers. These were reconditioned and fitted along with 257mm vented discs from Rally-Design. The calipers were rebuilt with a spacer kit (also from Rally-design) to increase the width around the wider vented disc. New longer mounting bolts with spacers were used, and a set of link pipes were fabricated to avoid the twin-feed piping that the Princess used.
The driver-side cylinder head of the BMW V8 is too wide to allow room for a conventional brake servo setup. And the space between the cylinder head and inner wing is too small to allow fitment of an extended pushrod/master cylinder and servo assembly.
The only solution i could find to the lack of space was to fit the master cylinder and remote servo assembly from a Lotus Elan. Quite a lot of 60s sports cars and saloons were aftermarket fitted with these remote servo systems (and the remote servo units are still available new).
In this picture the single-outlet master cylinder can be seen at the top right and the remote servo is mounted sideways against the o/s inner wing.
