🔧 CX-5 - Front Brake Pads & Rotor Replacement
You’ll remove the front calipers, replace the pads and rotors, then reassemble and bed-in the new pads. This restores braking performance and prevents vibration from worn or warped rotors.
Difficulty Level: Intermediate | Estimated Time: 2-4 hours
⚠️ Safety & Precautions
- ⚠️ Work on a flat, solid surface; support your CX-5 with jack stands before going under.
- ⚠️ Do not press the brake pedal with a caliper removed (the piston can pop out).
- ⚠️ Brake dust is harmful—avoid blowing it; use brake cleaner and wear a mask.
- ⚠️ Keep grease/oil off pad friction material and rotor faces.
- ⚠️ Battery disconnect is not required for front brakes.
🔧 Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Safety glasses
- Nitrile gloves
- Breaker bar 1/2"
- Torque wrench 1/2" (20-150 ft-lbs range)
- Socket set (10mm-21mm)
- 21mm socket
- 14mm socket
- 17mm socket
- Ratchet 3/8"
- Flathead screwdriver
- Caliper hanger hook (specialty)
- Brake caliper piston compressor tool (specialty)
- Wire brush
- Rubber mallet
- Brake cleaner spray
- Bungee cord
- Small wire/pick tool
- Drain pan

📋 Before You Begin
- Park on level ground, shift to Park, and set the parking brake.
- Place wheel chocks behind the rear wheels.
- Crack the front lug nuts loose about 1/4 turn using a 21mm socket and breaker bar before lifting.
- Open the hood and locate the brake fluid reservoir; you’ll watch the level when pushing the pistons back.
- “Caliper hanger hook” supports the caliper safely.
- “Piston compressor tool” pushes the piston back evenly.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and secure the front end
- Use a floor jack (rated 3-ton minimum) to lift the front of your CX-5 at the approved front jacking point.
- Set it down onto jack stands (rated 3-ton minimum).
- Remove the front wheels using a 21mm socket.
Step 2: Remove the front caliper (do not hang it by the hose)
- Turn the steering wheel to give yourself room to work on the caliper.
- Remove the two caliper slide-pin bolts using a 14mm socket.
- Lift the caliper off the bracket and support it with a caliper hanger hook (specialty) or bungee cord.
- Never let the caliper dangle by the hose.
Step 3: Remove old pads and hardware
- Pull the brake pads out of the bracket by hand; use a flathead screwdriver gently if stuck.
- Remove the stainless abutment clips (hardware) using a small wire/pick tool.
Step 4: Remove the caliper bracket
- Remove the two bracket bolts using a 17mm socket and breaker bar 1/2".
- Set the bracket aside.
- When reinstalling later: Torque to 79-98 Nm (58-72 ft-lbs).
Step 5: Remove the rotor
- If the rotor is stuck, spray the hub area with brake cleaner spray and let it soak briefly.
- Tap the rotor hat with a rubber mallet to break it free.
- Remove the rotor from the hub.
Step 6: Clean and prep the hub surface
- Use a wire brush to clean rust from the hub face (where the rotor sits).
- Spray again with brake cleaner spray and wipe clean.
- A clean hub helps prevent brake vibration.
Step 7: Install the new rotor
- Spray both rotor faces with brake cleaner spray to remove packing oil.
- Place the new rotor onto the hub.
Step 8: Service slide pins and reinstall the bracket
- Pull the slide pins out of the bracket by hand.
- Inspect the boots; replace if torn.
- Apply a thin, even coat of brake caliper slide pin grease (silicone) to the pins and reinstall them.
- Reinstall the bracket and tighten the bolts using a 17mm socket.
- Torque to 79-98 Nm (58-72 ft-lbs).
Step 9: Install new hardware and pads
- Install new abutment clips from the hardware kit.
- Clean the bracket pad lands with a wire brush if needed so the clips sit flat.
- Install the new pads into the bracket (they should slide smoothly).
Step 10: Compress the caliper piston
- Check the brake fluid reservoir level under the hood; be ready to remove a little if it rises too high.
- Use a brake caliper piston compressor tool (specialty) to push the piston straight back into the caliper slowly.
- If fluid needs to be removed, use the drain pan under the reservoir area and remove small amounts carefully.
- Go slow to avoid damaging the piston seal.
Step 11: Reinstall the caliper
- Place the caliper over the new pads and rotor.
- Install the slide-pin bolts using a 14mm socket.
- Torque to 25-34 Nm (19-25 ft-lbs).
Step 12: Reinstall wheels
- Install the wheels and hand-tighten the lug nuts.
- Lower the vehicle using the floor jack (rated 3-ton minimum).
- Tighten lug nuts in a star pattern using a torque wrench 1/2".
- Torque to 108-147 Nm (80-108 ft-lbs).
Step 13: Repeat on the other front wheel
- Repeat Steps 2 through 12 on the other front side.
- Do one side at a time to stay organized.
✅ After Repair
- With the vehicle still in Park, pump the brake pedal 10-15 times until it feels firm.
- Check brake fluid level and top off with Brake fluid (DOT 3) if needed.
- Start your CX-5 and do a slow test in a safe area; confirm normal braking and no pulling.
- Bed-in procedure (common for new pads/rotors): make 6-10 smooth stops from ~35 mph down to ~5 mph, with light cool-down driving between stops.
- Recheck lug nut torque using a torque wrench 1/2" after 50-100 miles.
