Jack up the front of the car and remove the road wheels, then extract the two retaining pins and the anti-rattle spring. Inspect the thickness of the disc pad friction material; if it has worn to 0.08 in (2.0 mm) or less, renew the pads on both front brakes as an axle set. Withdraw the pads by gripping their ends with pliers and brush any dust from the ends of the pistons and the pad recess. Use a syphoning device, such as a poultry baster, to withdraw some fluid from the brake fluid reservoir to accommodate additional fluid displaced when the caliper pistons are depressed. Depress the caliper pistons into their cylinders with a flat piece of wood or metal to accept the new thicker disc pads, ensuring the pistons remain square and are depressed until they reach their stops, while monitoring the reservoir fluid level to prevent overflow. Install the new pads, the spring, and the pins, then apply the foot brake hard several times before topping up the fluid reservoir. Finally, refit the road wheels and lower the car to the ground.
