GENERAL INFORMATION

The P.B.R. tandem master cylinder is of the compen­ sating type with integrally cast dual reservoirs. The master cylinder consists of a front and rear piston (in tandem), the front outlet on the master cylinder actuates the rear brakes. The two rear outlets on the master cylin­ der actuate the front disc brakes.

Provision is made internally for fitment of an external brake warning light switch to the tandem master cylinder body.

In the event of failure in one brake circuit, fluid will always remain in the other integrally cast reservoir.
