How to Replace the Front Disc Brakes With ABS
- 1). Loosen the lug nuts on the front wheels with the lug wrench or socket and breaker bar. Consult your vehicle's repair manual for proper socket sizing for the lug nuts, caliper bolts and caliper bridge bolts on your specific vehicle.
- 2). Lift the hood of the vehicle and remove the master cylinder cap. Lay the cap on top of the opening of the master cylinder to allow for ventilation but to keep any debris out of the reservoir.
- 3). Raise the vehicle with the lifting jack and place jack stands under the frame for support.
- 4). Remove the lug nuts and pull the wheels from the vehicle.
- 5). Turn the steering wheel in the direction opposite the side of the vehicle with the brakes you will replace first. For the left side brakes, turn the steering wheel to the right to access the caliper bolts more easily.
- 6). Remove the caliper bolts on the side of the caliper facing the vehicle. Pull the caliper from the disc rotor and rest it on a jack stand to avoid stress to the attached brake line.
- 7). Pull the rotor from the wheel hub. Tap the front of the disc with a hammer to break the bond of rust binding the rotor to the steering apparatus behind it.
- 8). Clean the wheel bolts and steering knuckle with a wire brush to provide a clean surface for the new rotor.
- 9). Clean the new rotor with brake cleaner before placing it onto the vehicle wheel bolts.

Pry the brake pad retaining clips away from the pads with a flat screwdriver of flat prying tool. Take the pads from the sides of the caliper. - 11
Open the brake bleed valve, located between the two caliper slide bolt openings, with a 10 mm wrench. Place the drip pan beneath the caliper to catch any brake fluid from the valve. - 12
Force the caliper piston into the side of the caliper with a C-clamp or vise-grip pliers. The brake fluid will flow from the bleed valve as the piston is compressed within the caliper side. Close the bleed valve once the piston is fully seated into the caliper side. - 13
Clean the inside of the caliper with a wire brush and apply a thin layer of brake grease to the inner walls of the caliper. - 14
Place the new brake pads onto the caliper and return the pad retaining clips over the brake pads with the screwdriver or pry tool. - 15
Place the caliper over the rotor and screw in the caliper bolts. - 16
Turn the steering wheel to the opposite side to access the other front brake and rotor. Repeat the steps for changing the brakes on the opposite side of the vehicle. - 17
Turn the steering wheel to bring the wheels to a neutral position. Replace the wheel/tire and screw on the lug nuts. - 18
Remove the jack stands and lower the vehicle to the ground. - 19
Tighten the lug nuts with the tire iron or lug wrench. - 20
Remove the mater cylinder cap from the container and fill the reservoir with brake fluid as needed. Consult your vehicle's maintenance guide in the owner's manual to determine the proper brake fluid needed to replenish the master cylinder. Replace the cap on the master cylinder.
