Brake systems - single line 1959-75

Note: This system is applicable to right hand drive and left hand drive 1959-75 models.

Brake Pipes
Pre-Assembled Copper Brake Pipe Kits
Each kit listed here includes a car set of pre-assembled copper brake pipes, which do not corrode and are easy to fashion with the correct bends to route them around the car. All kits are intended for saloon fitment. For Travellers, Estates, Vans and Pick Ups, please contact us - we will substitute a longer front to rear pipe in the appropriate saloon kit if required.

Pre-Assembled Brake Pipes
Alternatively, pre-assembled individual brake pipes can be supplied. If you order one of the part numbers below, you will receive a brake pipe assembly made from Cunifer, a superior material which bends to shape easily, doen't work harden and subsequently split and does not corrode. If desired, however, we will supply pipes in original Bundy material or copper - for either of these, please contact us.

For those converting their Mini to Metro-type four pot callipers and ventilated discs, we can supply an easy-to-fit and safe remedy to the problem of how to plumb in the dual line callipers when there's only one brake pipe to each front brake on a Mini. Our set of stainless steel braided hoses replace the standard front brake hoses and at the same time bridge the gap between the two ports on each calliper, removing the need to replicate the complicated dual line to each calliper set up of the Metro (or indeed the ERA Mini Turbo, which used similar callipers).
