CALIPER SCREW Fig. 3 - Exploded view of twin pot caliper assembly The disc brakes with higher thermal capacity are more suited for modern vehicles, which can take care of higher braking torques needed with higher speeds. C45+45 is the latest in Caliper design from Girling, which has a minimum corrosion of sliding members and can offer uniform wear on both the pads. The twin pots are inter-connected through a hole by casting itself, so that pressurised fluid from the master cylinder is acting on both the caliper pistons simultaneously. Colette Caliper Assembly consists of a Caliper carrier bolted to the stub axle and the body assembly slides on two sliding pins fixed in the bracket. The sliding pins are sealed against corrosion by dust covers thereby avoiding possible unequal sliding loads caused by dirt, corrosion. Drag of the pads is taken directly by the Carrier bracket, consequently the pins are only loaded by the weight of the caliper body.
