Wheel Brakes

Wheel brakes

Brake caliper and brake discs on front wheel




Front wheel brakes have ventilated brake discs (1) and sliding brake caliper (2) with special brake blocks (3) making for effective brakes and a long life expectancy.
The brake caliper has two main components: the caliper and the caliper mounting. The caliper slides in the caliper mounting on two locating pins protected by protective caps.
Braking force from the brake pads is absorbed by the caliper mounting, which transmits the force to the spindle. The caliper has a piston with an O-ring and dirt guard. The O-ring is designed to prevent brake fluid escaping and to return the piston to its resting position after braking. The dirt guard prevents dirt getting in between the cylinder and piston.
The pressure on the piston is transmitted directly to the nearest brake pad and via the caliper to the other brake pad. The caliper slides on the locating pins in the mounting to equalize the force on both sides of the brake disc. This sliding movement also compensates for the wear on the outer pad.

Brake caliper and brake discs, rear wheel




The rear wheel brakes have solid brake discs (4) and fixed brake calipers (5).
The brake disc hub (6) also acts as the parking brake drum (7).
The brake caliper consists of two halves bolted together and is located over the brake disc. Each half has a cylinder and piston, O-ring and dirt guard. The cylinders are connected via a channel in the casing. The O-rings are partly designed to prevent brake fluid escaping, and also to return the piston to its resting position after braking. The dirt guard prevents dirt getting in between the cylinder and piston. The brake pad (8) is held in place in the casing by locking pins.
