🔧 Front Brakes and Rotors - Replacement
The front brake pads and rotors wear together, so replacing both at the same time gives you smoother braking and helps prevent noise and vibration. On your CX-5, the front calipers must be compressed before the new pads and rotors go in.
Difficulty Level: Intermediate | Estimated Time: 2-3 hours
⚠️ Safety & Precautions
- Work on level ground and chock the rear wheels before lifting.
- Use jack stands; never rely on a floor jack alone.
- Brake parts may be hot after driving.
- Brake dust is harmful; wear a mask if dust is present and avoid blowing it into the air.
- Do not press the brake pedal with a caliper removed.
- Support the caliper with wire or a hook so the brake hose is not stretched.
- No battery disconnect is required for this repair.

- Raise the front and support it securely on jack stands.
- Remove both front wheels.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Remove the front wheels
- Use a 21mm socket and breaker bar to loosen the lug nuts, then remove the wheels.
- Set the wheels aside safely.
Step 2: Remove the caliper assembly
- Use a 14mm socket and ratchet to remove the two caliper slide bolt bolts.
- Lift the caliper off the bracket carefully.
- Hang the caliper with a bungee cord or mechanic’s hook. Never let it hang by the hose.
Step 3: Remove the brake pads and hardware
- Slide the old pads out of the caliper bracket.
- Remove the pad clips and hardware from the bracket.
- Use a wire brush to clean rust from the bracket contact points.
Step 4: Remove the caliper bracket
- Use a 17mm wrench and ratchet to remove the caliper bracket bolts.
- Take the bracket off the knuckle.
- Tighten on installation: Torque to 98 Nm (72 ft-lbs).
Step 5: Remove the old rotor
- Pull the rotor straight off the hub.
- If it is stuck, spray penetrating oil around the hub center and tap the rotor hat area with a rubber mallet.
- If your rotor has retaining screws, remove them with a Phillips screwdriver before pulling the rotor off.
Step 6: Clean the hub surface
- Use a wire brush and brake cleaner to clean the hub face until it is smooth and rust-free.
- A clean hub prevents rotor wobble.
Step 7: Install the new rotor
- Clean the new rotor with brake cleaner before installing it.
- Slide the rotor onto the hub and make sure it seats flat.
- If needed, install the retaining screw and snug it lightly.
Step 8: Reinstall the caliper bracket
- Put the caliper bracket back in place.
- Use a 17mm wrench and ratchet to install the bracket bolts.
- Torque to 98 Nm (72 ft-lbs).
Step 9: Compress the caliper piston
- Use a C-clamp or brake caliper compression tool to push the piston fully back into the caliper.
- Do this slowly and evenly.
- Watch the brake fluid level in the master cylinder so it does not overflow.
Step 10: Install the new pads and hardware
- Install the new pad clips in the bracket.
- Apply a thin layer of caliper slide pin grease to the slide pins and pad contact points.
- Install the new pads in the bracket.
- Use only a light film of grease.
Step 11: Reinstall the caliper
- Place the caliper over the new pads.
- Use a 14mm socket to install the slide bolts.
- Torque to 31 Nm (23 ft-lbs).
Step 12: Reinstall the wheels
- Install the front wheels and hand-tighten the lug nuts.
- Lower the vehicle to the ground.
- Use a 21mm socket and torque wrench to tighten the lug nuts in a star pattern.
- Torque to 108 Nm (80 ft-lbs).
Step 13: Set the brake pedal and inspect
- Before moving the vehicle, pump the brake pedal several times until it feels firm.
- Check the brake fluid level and top off only if needed.
- Inspect both front corners for leaks or loose parts.
✅ After Repair
- Test the brakes at low speed in a safe area.
- Listen for scraping or clicking noises.
- New pads should be bedded in gently for the first 200 miles.
- Avoid hard stops unless needed for safety during the break-in period.
