🔧 Front Brakes and Rotors - Replacement

The front brake pads and rotors on your Prius V wear together, so replacing both at the same time gives the best pedal feel and stopping power. On a hybrid, the brakes may feel a little different because the car blends regenerative braking with the hydraulic brakes, but the front brake job itself is straightforward.

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

⚠️ Safety & Precautions

• Work on a level surface with the parking brake engaged and the transmission in Park.
• Use jack stands under the vehicle before removing any wheels. Never rely on the jack alone.
• Hybrid vehicles can move unexpectedly if powered on. Keep the key fob away from the car while working.
• Do not press the brake pedal with a caliper removed.
• A brake piston compression tool is required to push the front caliper piston back in.
• No battery disconnect is normally required for this front brake service.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Loosen the front wheel

• Use the 21mm lug socket and breaker bar to loosen the front lug nuts 1/2 turn each.
• Do not remove them yet.

Step 2: Lift and support the vehicle

• Use the floor jack to raise the front of the vehicle at the approved front lift point.
• Set the car securely on jack stands.
• Remove the wheel with the 21mm lug socket.

Step 3: Remove the caliper

• Use the 14mm socket and ratchet to remove the two caliper slide bolts.
• Lift the caliper off the bracket and hang it with a bungee cord or mechanic's wire.
• Do not let the caliper hang by the hose.

Step 4: Remove the caliper bracket

• Use the 17mm socket and breaker bar to remove the two caliper bracket bolts.
• Remove the bracket from the steering knuckle.

Step 5: Remove the rotor

• If the rotor is stuck, use a flat blade screwdriver to back off any retaining screws if equipped.
• Pull the rotor off the hub.
• If it is rusted in place, tap it gently from behind with a rubber mallet.

Step 6: Clean the hub

• Use a wire brush to clean rust and debris from the hub surface.
• Spray the hub with brake cleaner and wipe it clean.
• A clean hub helps prevent brake wobble.

Step 7: Install the new rotor

• Spray the new rotor with brake cleaner to remove protective oil.
• Install the new rotor onto the hub.
• If there is a retaining screw, install it and snug it with the correct screwdriver.

Step 8: Reinstall the caliper bracket

• Reinstall the caliper bracket using the 17mm socket.
• Torque to 102 Nm (75 ft-lbs).

Step 9: Install new pads and hardware

• Remove the old pad clips and install the new brake hardware kit.
• Apply a thin layer of brake grease to the pad contact points and slide areas.
• Install the new brake pads in the bracket.

Step 10: Compress the caliper piston

• Use the brake caliper compression tool to slowly push the piston fully back into the caliper.
• Go slow to avoid damaging the seal.
• Make sure the brake fluid reservoir does not overflow.

Step 11: Reinstall the caliper

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

Step 12: Reinstall the wheel

• Put the wheel back on and hand-tighten the lug nuts.
• Lower the vehicle to the ground.
• Use the 21mm lug socket and torque wrench to tighten the lug nuts in a star pattern.
• Torque to 103 Nm (76 ft-lbs).

Step 13: Repeat on the other side

• Repeat the same steps on the opposite front wheel.
• Always replace front brake parts in pairs.
