Procedures
Procedures — Disc Brake Caliper - Inspection
△ CAUTION
If the caliper piston is replaced, install the same type of piston in the caliper. Never interchange phenolic resin and steel caliper pistons. The pistons, seals, seal grooves, caliper bore and piston tolerances are different.

INSPECTION The piston is made from a phenolic resin (plastic material) and should be smooth and clean. The piston must be replaced if cracked or scored. Do not attempt to restore a scored piston surface by sanding or polishing. The bore can be lightly polished with a brake hone to remove very minor surface imperfections (Figure 1). The caliper should be replaced if the bore is severely corroded, rusted, scored, or if polishing would increase bore diameter more than 0.025 mm (0.001 inch).
Procedures — Disc Brake Caliper - Cleaning
△ CAUTION
Do not use gasoline, kerosene, thinner, or similar solvents. These products may leave a residue that could damage the piston and seal.CLEANING Clean the caliper components with clean brake fluid or brake clean only. Wipe the caliper and piston dry with lint free towels or use low pressure compressed air.
Overhaul — Disc Brake Caliper - Disassembly
△ CAUTION
Do not blow the piston out of the bore with sustained air pressure. This could result in a cracked piston. Use only enough air pressure to ease the piston out.⚠ WARNING
Never attempt to catch the piston as it leaves the bore. This may result in personal injury.




- Remove brake shoes from caliper.
- Drain brake fluid out of caliper.
- Take a piece of wood and pad it with one-inch thickness of shop towels (1). Place this piece in the outboard shoe side of the caliper in front of the piston. This will cushion and protect caliper piston during removal.

Disc Brake Caliper - Operation




OPERATION When the brakes are applied fluid pressure is exerted against the caliper piston. The fluid pressure is exerted equally and in all directions. This means pressure exerted against the caliper piston and within the caliper bore will be equal (Figure 1). Fluid pressure applied to the piston is transmitted directly to the inboard brake shoe. This forces the shoe lining against the inner surface of the disc brake rotor. At the same time, fluid pressure within the piston bore forces the caliper to slide inward on the mounting bolts. This action brings the outboard brake shoe lining into contact with the outer surface of the disc brake rotor. In summary, fluid pressure acting simultaneously on both piston and caliper, produces a strong clamping action. When sufficient force is applied, friction will attempt to stop the rotors from turning and bring the vehicle to a stop. Application and release of the brake pedal generates only a very slight movement of the caliper and piston. Upon release of the pedal, the caliper and piston return to a rest position. The brake shoes do not retract an appreciable distance from the rotor. In fact, clearance is usually at, or close to zero. The reasons for this are to keep road debris from getting between the rotor and lining and in wiping the rotor surface clear each revolution. The caliper piston seal controls the amount of piston extension needed to compensate for normal lining wear. During brake application, the seal is deflected outward by fluid pressure and piston movement (Figure 2). When the brakes (and fluid pressure) are released, the seal relaxes and retracts the piston. The amount of piston retraction is determined by the amount of seal deflection. Generally the amount is just enough to maintain contact between the piston and inboard brake shoe.
