5 If new brake pads are to be fitted, the caliper piston must be pushed back into the cylinder to make room for them. Either use a G-clamp or similar tool, or use suitable pieces of wood as levers. Clamp off the flexible brake hose leading to the caliper then connect a brake bleeding kit to the caliper bleed nipple. Open the bleed nipple as the piston is retracted, the

4.4b Pivot the caliper away and suspend it from the coil spring using a length of wire or string surplus brake fluid will then be collected in the bleed kit vessel (see illustration 4.4j). Close the bleed nipple just before the caliper piston is pushed fully into the caliper. This should ensure no air enters the hydraulic system. Note: The ABS unit contains hydraulic components that are very sensitive to impurities in the brake fluid. Even the smallest particles can cause the system to fail through blockage. The pad retraction method described here prevents any debris in the brake fluid expelled from the caliper from being passed back to the ABS hydraulic unit, as well as preventing any chance of damage to the master cylinder seals.

4.4c Remove the inner and outer pad from the caliper mounting bracket

4.4d Check the pad support plates (arrowed) in the caliper mounting bracket; if they are worn or distorted, renew them

4.4e Measure the thickness of the pad's friction material; if it's less than 2.0 mm, renew all four pads

4.4f Check the caliper guide pins slide easily and the rubber gaiters are not damaged

6 Depress the brake pedal repeatedly, until the pads are pressed into firm contact with the brake disc, and normal (non-assisted) pedal pressure is restored.

7 Repeat the above procedure on the remaining front brake caliper.

8 Refit the roadwheels, then lower the vehicle to the ground and tighten the roadwheel bolts to the specified torque.

9 Check the hydraulic fluid level as described in Weekly checks.

Caution: New pads will not give full braking efficiency until they have bedded-in. Be prepared for this, and avoid hard braking as far as possible for the first hundred kilometers or so afterpad renewal.
