1. With the front of the car jacked up and safely supported on stands, remove the road wheel.
2. If the calliper is being removed for overhaul, remove the brake pads as detailed previously, then depress the brake pedal to move the calliper pistons outwards from their wheel cylinders and thus facilitate removal of the pistons later.
3. If the calliper is to be removed from the car, as opposed to merely being moved to one side to allow access to another component, slacken the brake hose at the calliper.
4. Remove the two bolts securing the brake calliper to the swivel hub and slide the calliper assembly off the brake disc.
5. If the calliper is to be removed, unscrew the calliper from the brake hose and cap the hose end to prevent loss of fluid. Otherwise, merely suspend the calliper from a suitable point on the suspension to avoid straining the brake hose.


Installation is a simple reversal of the removal procedure, with special attention to the following points:
a) If the calliper was completely removed from the car, screw it onto the brake hose before attaching it to the swivel hub.
b) Ensure that the brake hose is positioned so that it is not twisted and will not foul the body or suspension components during steering and suspension movement.
c) Tighten the calliper mounting bolts to 38 lb ft (5.3 kg m).
d) If disconnected, finally tighten the brake hose at the calliper connection once the calliper is bolted in position. e) If the brake pads were removed, refit them in the calliper as detailed previously. f) If the braking system was broken in to, bleed the brakes as detailed later in this section.

Calliper Overhaul

The calliper must be removed from the brake disc to allow overhaul, but it need not be completely removed from the car.
The brake hose can remain attached.
1. Thoroughly clean the outside of the calliper, especially around the pad recess and the cylinder bores.
2. Remove the pistons, one at a time, from their respective cylinder bores. Extract the dust seal and retainer from the top of the cylinder bore, and the piston seal from its groove in the cylinder bore.
3. Clean and inspect the components of the calliper as detailed under 'HYDRAULIC SYSTEM OVERHAUL' at the beginning of this section. If the cylinder bore is scored, corroded or showing signs of wear, the calliper should be renewed. If only the pistons are damaged, new pistons can be fitted.
4. Lubricate the cylinder bores with clean brake fluid and fit a new piston seal to the groove in one of the cylinder bores. Lubricate the piston and insert it, crown first, into the bore with the cut-away at the top. Press the piston into the bore until approximately 0.32 in (8 mm) remains protruding.
5. Fit a new dust seal into the retainer ring and lubricate the lips with clean brake fluid. Fit the seal and retainer over the piston and press them into position at the top of the cylinder bore. Press the piston fully into the bore.
6. Assemble the other piston to the calliper in a similar manner. If the calliper is still connected to the car, it may be necessary to open the calliper bleed valve to enable the second piston to be pressed home in its bore.
