Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Fully remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set (typically 13mm or 15mm).
2. Carefully slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the new brake pads for compatibility and install them in the caliper bracket.
5. Apply brake grease to the backing of the new pads (if required by the manufacturer).
Tools Required: Socket set, bungee cord, brake grease.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for any scoring or warping. If damaged, proceed with replacement.
2. Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
3. Install the new rotor, ensuring it is seated properly.
4. Tighten the retaining screws to the manufacturer’s specified torque.
Tools Required: Torque wrench, socket set.

5. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper over the new pads and rotor.
2. Tighten the caliper bolts to the specified torque value.
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench, socket set.

6. Lower Vehicle and Final Checks

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Tighten the lug nuts in a crisscross pattern to ensure even pressure.
3. Pump the brake pedal several times to seat the new pads.
4. Check brake fluid level and top off if necessary.
Safety Warnings: Ensure the vehicle is securely supported before working under it. Allow the brakes to cool before touching any components.
