🔧 Front Brake Pads and Rotors - Replacement

Front brake pad and rotor replacement on your Prius restores braking performance and helps remove vibration, squealing, or pulsing from worn parts. Since this is a hybrid, the front brakes may wear slower than on a normal gas car, but the service procedure is still straightforward if you work carefully.

Difficulty Level: Intermediate | Estimated Time: 2-3 hours

• Brake dust can be harmful. Do not blow it off with compressed air.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front end

• Use the floor jack to raise the front of the vehicle at the proper front jacking point.
• Place jack stands under the front support points and lower the vehicle onto them.
• Remove both front wheels with the 21mm lug wrench or socket.

Step 2: Remove the caliper

• Use the 14mm socket and ratchet to remove the caliper slide bolts.
• Lift the caliper off the bracket and support it with a bungee cord or hook.
• Do not let the caliper hang by the brake hose.

Step 3: Remove the brake pads and bracket

• Slide the old brake pads out of the bracket.
• Use the 14mm socket and breaker bar if needed to remove the caliper bracket bolts.
• Remove the caliper bracket from the knuckle.

Step 4: Remove the rotor

• If the rotor is retained by a small screw, use the Phillips screwdriver or 6mm hex bit socket as needed to remove it.
• Pull the rotor off the hub.
• If it is stuck, tap the rotor hat with a rubber mallet or strike it from the back side evenly.

Step 5: Clean and prep the hub

• Use a wire brush to clean rust from the hub face.
• Spray the hub and bracket with brake cleaner and wipe dry with shop towels.
• A clean hub helps prevent rotor wobble.

Step 6: Install the new rotor

• Install the new rotor onto the hub.
• Reinstall the rotor retaining screw if equipped and tighten snugly with the correct Phillips screwdriver or 6mm hex bit socket.

Step 7: Reinstall the caliper bracket and pads

• Install the caliper bracket using the 14mm socket.
• Torque to 105 Nm (77 ft-lbs).
• Install the new pad hardware and new brake pads.
• If the new pads include shims, install them exactly as supplied.

Step 8: Compress the caliper piston

• Use a C-clamp or brake caliper compression tool (specialty) to push the piston back slowly.
• Make sure the old inner pad or a flat block is used to protect the piston face.
• Compress the piston slowly and evenly.

Step 9: Reinstall the caliper

• Set the caliper over the new pads.
• Install the slide bolts with the 14mm socket.
• Torque to 34 Nm (25 ft-lbs).

Step 10: Reinstall the wheel

• Put the wheel back on and start the lug nuts by hand.
• Use the 21mm lug wrench or socket to snug them in a star pattern.
• Lower the vehicle, then torque the lug nuts to 103 Nm (76 ft-lbs).

✅ After Repair

• Press the brake pedal several times before moving the vehicle.
• Check the brake fluid level in the reservoir.
• Test drive at low speed first and confirm the pedal feels firm.
• Listen for rubbing or clicking, and recheck lug nut torque after driving.
• For the first 200 miles, avoid hard braking to help seat the new pads and rotors.
