Disc brake caliper assembly
The caliper has one cylinder and is attached to the steering knuckle with two bolts. The pressure in the hydraulic drive system that occurs when the brake pedal is depressed is transferred to the brake pads. Equal forces act on the piston and the bottom of the cylinder. This moves the piston outward and the caliper inward, forcing the pads to compress the brake disc. The friction of the brake pads against the disc causes the vehicle to brake.
- Replace with new all components for which there is a replacement in the repair kit designed to service the caliper.
- Lubricate all rubber parts with clean brake fluid to facilitate reassembly.
- It is not allowed to blow the parts of the brake mechanism with compressed air containing oil, because. this may damage the rubber elements.
- If any hydraulic element was removed or disconnected during the repair, it may be necessary to bleed the brake system completely or partially. See Part 4A. Hydraulic brakes.
- Brake pads should be changed as a set, on both wheels of the axle.
- The tightening torques for threaded connections are for dry, unlubricated fasteners.
- All maintenance operations must be carried out on a clean table, not contaminated with any oil.
