1 Firmly apply the handbrake, then jack up the front and rear of the car and support it securely on axle stands (see “Jacking and vehicle support”).

2 For a quick check, the front brake disc pads can be inspected without removing the front wheels by inserting a mirror between each caliper and roadwheel (see illustration). If any one pad is worn down to the minimum specified thickness, all four pads (on both front wheels) must be renewed.

3 It is necessary to remove the rear wheels in order to inspect the rear disc pads. The pads can be viewed through the top of the caliper after removing the blanking spring clip (see illustration). If any one pad is worn down to the minimum specified, all four pads (on both rear wheels) must be renewed.

4 For a comprehensive check, the brake disc pads should be removed and cleaned. The operation of the caliper can then also be checked, and the condition of the brake discs can be fully examined on both sides. Refer to Chapter 10 for further information.

5 On rear drum brake models, the brake shoe friction material can be inspected for wear without removing the roadwheels. Working beneath the vehicle, prise the plug from the brake backplate, and using an inspection lamp or torch, check that the friction material thickness is not less than the minimum given in the Specifications (see illustration). If any one of the shoes has worn below the specified limit, the shoes must be renewed as an axle set (4 shoes).

6 At the same interval, check the function of the brake fluid level warning light. Chock the wheels, release the handbrake and switch on the ignition. Unscrew and raise the brake fluid reservoir cap whilst an assistant observes the warning light: it should come on as the level sensor is withdrawn from the fluid. Refit the cap.

7 On completion, refit the wheels and lower the car to the ground.
