When it comes to saving money maintaining your car, changing your own brake pads is one of the best ways. Another thing to consider is whether you should change out just your brake pads or both the brake pads and rotors. Most manufacturers recommend changing the brake pads and rotors at the same time. While we generally agree, if your brake rotors are evenly worn and have sufficient thickness remaining, you can just replace the brake pads.
To perform this DIY, check out this helpful tutorial above from Adam Saruwatari Xtreme. Detailed steps can be found below.

Caliper bolts: 63 ft-lbs
Step 1: Prepare your vehicle and work area.
- Ensure your car is parked on a flat surface and the brakes are cool.
- Put on eye protection, gloves, and a respiratory mask as brake dust is extremely hazardous.
- Gather tools and parts.
Step 2: Extract a small amount of brake fluid from the brake fluid reservoir.
- Extract a little bit of brake fluid from the reservoir to prevent it from overflowing during this procedure as shown in this video.
- To do this, open front compartment area, remove the plastic panel covering brake fluid reservoir.
- Unscrew the brake fluid reservoir cap, remove the mesh filter inside, and extract a little bit of brake fluid using a new turkey baster.
- Save this brake fluid in a clean container, so you can re-use it later.
- Reinstall the brake fluid reservoir cap when you are done to prevent debris from getting in.
Step 3: Raise your vehicle off the ground.
- You can raise your car one corner at a time or raise the entire vehicle.
- To do this, either use a vehicle lift or a jack and jack stands.
- NEVER rely on a jack to keep your car up; use jack stands to safely support your vehicle.
- Also be sure to use wheel chocks to prevent your car from rolling.
- To lift your vehicle on jack stands, check out this helpful video from the YouTube channel CarFanatic.
- Note: Be sure to loosen your wheel bolts before you lift the wheel off the ground.
Step 4: Gain access to the brakes by removing the wheel.
- Remove the wheel using a 19mm socket and breaker bar.
- Place two wheel guide bolts to help you remove the wheel.
Step 5: Starting with the front brake calipers, remove the brake pad spring clip.
- If you are replacing the brake rotors, start by applying WD-40 or another penetrating oil to all the fasteners that hold the brake caliper in place.
- Remove the black pin which holds in the brake pad spring clip by using a 13mm socket to remove the nut, then gently punch out the pin as shown in this video.
- Keep some pressure on the spring clip, so it doesn’t pop out.
Step 6: Remove the brake pads.
- Using a brake pad spreader, spread out the brake pads. This will allow the new brake pads, which are thicker, to fit over the rotor.
- Carefully, pull out the brake pad sensor from the brake pad; disconnect the brake pad sensor completely.
- Next, use a putty knife to separate the brake pads from brake pad dampers (the backings stuck to the pads).
- Fully remove the old brake pads out of the caliper.
- Note: If you are only replacing the brake pads, skip to step 10.
Step 7: Remove the brake caliper.
- To replace your brake rotor, you will need to remove the brake caliper.
- Start by removing the brake line bracket which is held on by a 10mm bolt.
- Take string or bungee cord and tie the brake caliper onto the suspension. This will prevent the brake caliper from hanging by the brake line when you remove the caliper.
- Remove the brake caliper by using a 10mm hex socket to remove the two caliper bolts.
- Move the brake caliper to the side, so you can remove the brake rotor.
Step 8: Remove the brake rotor.
- Remove the 2 screws holding the brake rotor in place; if needed, use an impact screwdriver to break them loose.
- If you have difficulty getting the brake rotor off, apply some penetrating oil to where it meets the hub and use a hammer to lightly tap around the wheel hub area; let the penetrating oil get to work for a few minutes, then use a rubber mallet to loosen the rotor.
- Note: For the rear brakes, make sure your parking brake is not engaged or you won’t be able to get the rotors off.
Step 9: Install the new brake rotor.
- IMPORTANT: Be sure to install the correct side rotor on each corner.
- Apply anti-seize to where the rotor meets the wheel hub and to the brake rotor set screws to prevent them from seizing in the future.
- Install the new brake rotor and hand tighten the set screws.
Step 10: Install the new brake pads.
- Apply brake lubricant around the edges of the brake pad to prevent squealing. DO NOT get any on the surface of the brake pad!
- If your brake pads do not come with an adhesive tape backing on them, we recommend applying 3M adhesive 467MP tape (see parts section) to the back; this will prevent squealing.
- Connect the new brake pad sensors to the brake pads.
- Insert the new brake pads into the brake caliper.
Step 11: Re-install everything.
- Re-install everything in reverse.
- For the brake caliper bolts, apply thread locker and torque them to 63 ft-lbs.
- Hand tighten the 10mm bolt that holds the brake line in place.
- Torque wheel bolts to 118 ft-lbs.
Step 12: Repeat the steps on the remaining corners.
- The rear brake calipers do not have a pin that secures the brake pads.
- The rear brake calipers are closed, so you cannot pull the brake pads out without removing the caliper first.
Step 13: Lower the vehicle to the ground.
Step 14: Top off the brake fluid reservoir as necessary.
- Get inside the car and give your brakes a few pumps until the pedal is firm.
- Top off your brake fluid reservoir to just under the max line; do not overfill.
- Re-install the brake fluid reservoir mesh filter, cap, and plastic cover.
- Clean up and put all of your tools away.
- Congrats. You’re all done and just saved a bunch of money!

What a great resource! I have a 2007 997.1 turbo with ceramic (PCCB) brakes. I love them (but not the cost). One or two close calls and you know they have paid for themselves infinitely. Quick question; Is there any difference in replacing the brake pads for the PCCBs than what you have shown above?

Hi Robert. The steps should be the same. Just be very careful not to hit the ceramic rotors with your wheels or tools, so you don’t damage them. Let us know how it goes!
