Brake Pads

You need to drain two-thirds of the brake fluid through a siphon from the master cylinder reservoir. After lifting the car and putting it safely in place you can take away the wheel assembly with its tire. When taking out the 2 caliper pin bolts keep all brake parts away from the flexible brake hoses to protect them from damage. Hang the caliper bracket assembly safely with wire to shield the brake hose while you detach it from its position. Take off first the 2 brake pads (2, 3) from their position before handling their retainers and insulators. During inspection you must check brake pads for thickness which should remain above 7.5 mm (0.295 inch) otherwise replace them both. Fit the Brake Pad insulators onto the brake pads pairs (3 and 4), and put the Brake Pad retainers (2 pieces). Install the Brake Pad with the indicator on the inside of the caliper assembly. Fit the brake pads onto caliper sides while ensuring located boots stay firmly in their specified spaces. Position the caliper on the caliper bracket before tightening it to 27 nm (20 ft. Lbs) with the 2 caliper pin bolts. Put back the tire and wheel parts while placing the vehicle down and completing the master cylinder reservoir. Press the brake pedal multiple times while starting the engine lets the caliper piston take its position before smoothing out the pads.

Remove the 2 caliper pin bolts and ensure that the brake components do not hang from the flexible brake hoses to avoid damage.

Remove the caliper assembly from the caliper bracket and suspend it with wire to prevent damage to the brake hose.

Accelerate the vehicle to 48 km/h (30 mph).

Attach the caliper to the caliper bracket and secure it with the 2 caliper pin bolts, tightening them to 27 Nm (20 ft. lbs.).

Remove the 2 brake pads, the 2 brake pad retainers, and the 2 brake pad insulators. Measure the brake pads; if the thickness of the pad and plate is less than 7.5 mm (0.295 inch), replace them.
