To be replacing and removing the brake pads, commence by uncapping the brake fluid reservoir and using a suction gun to siphon off two-thirds of the fluid. Next, loosen wheel lug nuts, lift the vehicle up, and support it by jackstands that are secure. Remove the wheels at front or rear ends; check the condition of the disc. If machining is required, remove disc, calipers and pads. For the removal of frontal pad wash brake assembly with brake system cleaner and push piston back into bore with C-clamp. Take out bottom caliper mounting bolt, rotate caliper upwards till inner & outer brake pads are removable .Take out anti-rattle clips and check them for wear. Lubricate caliper mounting bolts when reinstalling upper & lower anti-rattle clips as well as outside/inside ones.Apply 5 force on tightness of mounting bolt.Presently you can place wheel into position; lower your car down until tire touches ground; tighten lug nuts.Finally apply then release brake pedal before checking fluid level prior to test drive of brakes.Rear pad removal can only be accomplished after washing brake assembly as well as releasing parking break cable in addition to removal of lower caliper mounting bolt.Turn up caliper to detach from retainers plus take out pads.Installing requires putting anti-squeal compound on backing plates in addition to rotating it so that piston goes inside while new pad rattle clip should be attached.Lubricate caliper guide pin when turning down caliper installing mounting bolt.Reconnecting involves installing parking break cable henceforth put wheel while lowering auto; tightening lug nuts.Release brake pedal but do not hold it instead repeat until all air is removed from hydraulic circuit.Check if there is enough fluid otherwise top up reservoir before testing braking system.

To install, lubricate the caliper mounting bolts, install the upper and lower anti-rattle clips, and install the outer and inner pads. Position the caliper and tighten the mounting bolt. Install the wheel, lower the vehicle, and tighten the lug nuts. Finally, apply and release the brake pedal, check the fluid level, and test the brakes before driving.

Install the brake pads on the opposite wheel, then install the wheels and lower the vehicle. Add brake fluid to the reservoir until it's full. Pump the brakes several times to seat the pads against the disc, then check the fluid level again. Check the operation of the brakes before driving the vehicle in traffic. Try to avoid heavy brake applications until the brakes have been applied lightly several times to seat the pads.

Work on one brake assembly at a time, positioning a drain pan underneath and cleaning the caliper and surrounding area with brake system cleaner. Use a C-clamp to push the piston back into its bore, being careful not to overflow the fluid in the master cylinder.

Work on one brake assembly at a time. Push the piston back into the caliper bore to provide room for the new brake pads. A C-clamp can be used to accomplish this. Remove the C-clamp. Remove the two caliper mounting bolts. Lift the caliper off the disc and remove the outer pad. Pull the inner pad out of the caliper and remove it. Fasten the caliper out of the way with a piece of wire to prevent damage to the brake hose. Remove the mounting bolt seals, then use a scribe or similar tool to extract the rubber bushings from inside the caliper ears. Clean the caliper and mounting bolts and check them for corrosion and damage. Replace the bolts with new ones if they're significantly corroded or damaged.

On older models, remove the caliper mounting bolts and lift the caliper off the disc, removing the outer and inner pads.
