front circuit of the cylinder supplies the lower pistons of each caliper. Not all models in the range covered have the same master cylinder, as the diameter has been selected to be suitable for carrying capacity, version, etc. Fig. 8.1 shows how the various components are connected with each other.
A brake servo unit is fitted, the vacuum being supplied by a separate vacuum pump, driven by the engine. Not all pumps are of the same make. A brake pressure regulator regulates the brake pressure to the rear wheels.
The handbrake operates the rear wheels. The rear wheels should be locked when the handbrake lever is pulled 4 to 5 notches.
