What you will need

A list of tools and parts required to change the brake pads and rotors on your Mazda CX-9 has been provided below.


  1. Start by engaging the parking brakes and ensure the gear shifter is in Park. Next, access the brake fluid reservoir. Open the hood and remove the brake fluid reservoir cap. This is necessary and will make it easy later when pressing the caliper pistons in.

  2. Loosen Lug Nuts.  Before raising the car, make sure to break loose the lug nuts. Do not remove them yet; just loosen them a turn or so. mazda cx9 front brake pad and rotor replacement

  3. Raise Vehicle. Use a floor jack to raise one of the front wheels. Carefully raise the front of your car with a jack and then support both sides of the car's front with jack stands.

  4. Support with Jack Stands. Always support the vehicle with jack stands. Do not rely only on a jack. Besides the jack stands and jacks, we recommend that you slide the wheels under the car. Remove tire. Remove lug nut. mazda cx9 front brake pad diy

  5. Remove the brake fluid cap. Remove the brake fluid container's cap, which is at the back right of the engine bay towards the driver's side.

  6. Press the caliper piston. If you plan on using a flat screwdriver to press the caliper piston in, this is the time. If you are using the C-Clamp or Brake Pad Compression tool, skip this step. How to change front brake pads

  7. Remove Caliper Bolts. Locate the two bolts on the back of the front brake caliper. Remove both bolts. Use a 17mm socket and a ratcheting wrench to loosen the lower and upper caliper bolts on the caliper's back and pull each bolt slightly out. You need to slide them out to allow room to remove the caliper. Mazda CX-9 Brake Pads & Rotors

  8. Remove Brake Pads. Once you remove the two bolts, you will pull out the caliper and remove the brake pads. Loosen the two rotor retaining bolts using a Phillips screwdriver. These bolts can be difficult to come out. mazda cx-9 front brake removal mazda cx-9 tools required to change brake pads

  9. Notice the location of the wear sensors. If your vehicle uses wear sensors, notice the sensor's location and the orientation of the wires. You need to make sure to install the new sensors in the same way.

  10. Secure the brake caliper. Use a wire to secure the brake caliper. Do not let the brake caliper hang as this can cause damage to the brake hose. Lift the caliper off the brake pads and tie it with a rope to the strut to keep it from falling and void, putting tension on the brake line. mazda cx-9 installing brake pads with clips

  11. Remove Brake Pad Bracket. Before you can remove the rotor, you need to remove the brake pad/caliper bracket. It is held in place with two bolts. Typically these are 17mm bolts. Remove the bolts using a breaker bar. mazda cx-9  front brake diy mazda cx-9 front brake caliper replacement

  12. Removing the old rotor can be tricky. First, remove the screw that holds the rotor secure. Next, you need to remove the rotor. Try wiggling the rotor back and forth. If the rotor does not come loose, you may have to use a hammer to get it off. mazda cx-9 front brake pad change cost Also, spray penetrating oil and let it sit for 10 minutes before you try to remove the rotor. mazda cx-9 front brake diy

  13. It is time to install the new rotor. We recommend that you clean the hub area with a steel wire brush before installing the new rotor. Compare the old and the new rotors to make sure they are the same size and thickness, then fit the new rotor carefully. If you are installing new slotted rotors, make sure they are fitted correctly to spin in the proper direction.

  14. Install the new rotor. Slide the new rotor in place. Tighten the rotor retaining bolts. mazda cx-9 front brake pad rotor change

  15. Next, install the bracket and tighten the two bolts on the back. Remember, the bolts on the back of the brake pad bracket need to be tight. If you are using a torque wrench, make sure to torque them at 70 ft-lbs. mazda cx-9 front brake pad rotor change

  16. Using a dry towel or a rag, you can clean the dirt from the calipers and the pistons with a special spray for cleaning brake parts. mazda cx-9 front brake pad rotor change

  17. The new brake pads will probably be thicker than the older ones; you will need to use an even surface (e.g., the old brake pad) to press back the caliper pistons so you would be able to fit the new brake pads inside the brake calipers. A C-clamp can be used to compress the pistons backward. Don't push the pistons too far, only until the pistons are in line with the rubber dust boot. Put the new brake pads in their place; make sure they are tightly and well-fitted.

  18. After fitting the new brake pads, you might experience light braking noise or squeaking; to eliminate that noise, you can use CRC Disc Brake Quiet for brake pads. 

  19. Install new caliper. Loosen the caliper from the rope carefully and tighten the lower caliper bolt using a 17mm socket and ratcheting wrench. Use brake caliper grease to lubricate the caliper bolts. Install a new caliper and tighten the two bolts. mazda cx-9 front brake pad rotor change

  20. Refit the front wheel and spin the lug nuts with your hand. Tighten the lug nuts in a criss-cross pattern. Lower the vehicle until it puts some weight onto the wheel to prevent it from spinning, then complete tightening the lug nuts.   mazda cx-9 front brake pad rotor change

  21. Get into the driver's seat, start the car up and pump the brake pedal a few times to restore brake pressure.

  22. Check the brake fluid level in the container and make sure that it is above the "MIN" (minimum) indicator. If it is low, add the recommended brake fluid. Once the brake fluid level is correct, replace the brake fluid container cap.



  • If your brake pedal used to feel soft, you might need to bleed the brake lines to flush out any air bubbles and/or replace the old brake fluid with new DOT3 brake fluid.

  • Regularly check your car for any brake fluid leak signs and make sure that the brake fluid volume did not decrease significantly.

  • Check that the lug nuts are tightened properly.
