How to Change Disc Brake Pads Over time, the brake pads on your disc brakes will eventually wear out. These will have to be replaced a few times over the life of your vehicle. Follow these steps to learn how to change your disc brake pads. Keep in mind, when replacing brake pads, you should replace both the pads on both front or rear tires at the same time, or all four, if needed.
You will need a jack, jack stand, tire iron, a wrench, c-clamp, and new brake pads.
Remove the wheel. Park on a level surface and jack up the car to raise the wheel you want to work on first. Use the tire iron to remove the wheel’s lug nuts and take off the tire.
Remove old brake pads. Remove one of the bolts that holds the caliper. You will then be able to rotate the caliper away from the wheel and it should stay opened on its own. Look at how the current pads are arranged and then pull them out. Use a C-clamp or other tool to compress the brake piston to its fully open position.
Install new brake pads. Slip the new brake pads into position and make sure they clip into place. Apply brake lubricant to the piston, bushings, caliper bolt, etc.
Close the caliper. Rotate the caliper back into position and replace the bolt, ensuring it is tight and secure.
Replace the tire. Put the tire back on the wheel. Tighten the lug nuts by hand and then use the tire iron to tighten them as much as you can. Lower the vehicle back to the ground.
Test the brakes. Turn on the engine, but leave the parking brake engaged. You will need to pump the brake pedal to push the brake fluid back through the system. Release the parking brake and slowly drive forward and test your brakes.
