DUAL CIRCUIT MASTER CYLINDER KITS TR2-4A

The Triumph TRS raced at Le Mans with a system of dual circuit brakes, which was also installed on the Conrero and other prototypes by Triumph. This system, which has now been reproduced by Revington TR, is in use on Ex-Works TR4 rally cars 3VC and 6VC and is therefore well proven. Whilst initially offered for the TR4-4A, can now be supplied for TR2-3B and TR derivatives as well.

The kits are offered with two types of reservoir:

1. Metal canister as used on the TR3A with an internal divider to ensure fluid is separated between front and back systems. The reservoir is mounted on the side of the master cylinder support bracket. The metal canister cannot be used on TR4 - 4A as the pipework from the reservoir to the brake master cylinders is too close to the steering column for safety..
2. Two clear plastic reservoirs mounted on the side of the master cylinder support bracket.

These kits include all pipes, cylinders for brakes and clutch, brackets, balance bars and reservoir(s). Available for both left-hand and right-hand drive. The TR4-4A kits are a direct replacement fit.

When fitted to a TR2-3B minor bulkhead alterations are needed to widen out the pocket aperture and a larger pocket is required. In addition the pedal assembly needs to be exchanged for one with the top fulcrums modified to TR4-4A specification to allow for the spacing required to accommodate two brake master cylinders. Revington TR can exchange your pedals if required. Order part no. RTR4168 (suffix LEXK or REXK for LHD or RHD- see below) The new wider pocket and back plate are sold as a kit part number RTR7180K. There is more detail under each part number and even more detail and explicit instructions supplied with each kit Dual Circuit Brake kit. see below
