How to Change Your Brake Pads

Decide whether to replace the gasket on all four wheels or two tires. You will replace the mat on the front or rear wheels. For a complete job and the best results, do all four wheels. If your budget and / or time limit is not allowed, please execute before and after. The front wheel brake calipers, mats and rotors are larger than the rear, and the cost is higher. The procedures are basically the same.

By determining whether the brake is for two wheels or four, it will also decide whether you insert the front, rear or both ends of the vehicle. If you have an impact gun to remove the lug nut from the wheel, you can continue to rise. If you have to use the crowbar to remove the lug nut, then when the wheel falls on the ground, you should release it (break it). Once the wheels are in the air, they may be free to rotate, which will make it very difficult to remove the lugs nuts, if not impossible. Securely insert the vehicle and then support it on the socket. Do not work while the vehicle is supported only by jacks. Jack failed, you might put your life at risk.

Once you have removed the wheel, remove it and slide it out with a large screwdriver, and remove the crash pad (if applicable). Next, let's remove the caliper. For the front wheels, it may be necessary to turn the diverter completely to the right or to the left to enter the caliper guide bolts. Normally, they are located on the back of the caliper. The caliper guide bolts may have a dust cover. These will be made of rubber or plastic. With a small screwdriver pry out. Once the lid is removed, the bolt head will be exposed.

Use your ratchet and the appropriate socket or Allen drill, remove the 2 bolts. Grasp the caliper and pull it out of the rotor. You may need to use a large screwdriver to loosen it. Remove the two brakes from the caliper and, if necessary, pry. A brake pad can be attached to the caliper piston by a clip. Loosen the clip and the mat will fall out. If your vehicle is equipped with a brake sensor cable, carefully remove the wires from the electrode plate. The sensor line will be on the right or left of a pad. Remember which wheels have wires.

Now it's time to re-compress the caliper piston. When the brake pads are worn, they cause the piston to further push the caliper. The piston must be pushed back so that you can install the new thicker brakes in place. You can use one of the old pad and piston compression tool or c-type clip to push it back. Simply place the old pad on top of the piston and tighten the tool or c clip to press it back in place.

When you are ready to install a new gasket, use a bungee rope to hang the spring or hood on the heavy calipers. Brake lines do not jam because they are heavy and can damage the lines. Place several wipes under the parts, spray the brake parts cleaner onto the calipers, bolts, brackets, etc., and thoroughly clean all the contents. You may also need to use a wire cleaning brush.
