Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen the lug nuts on the wheel using a lug wrench.
2. Raise the vehicle using a jack and secure it on jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: C-clamp (or brake caliper tool), socket set
Sub-steps:
1. Locate the brake caliper and remove the caliper bolts using a socket.
2. Carefully lift the caliper away from the rotor; support it with a bungee cord or similar to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Use a C-clamp to compress the caliper piston back into the caliper housing.
5. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench, socket set
Sub-steps:
1. Remove the brake rotor by taking off any retaining screws or clips.
2. Inspect the rotor surface for scoring; if damaged, replace with a new rotor.
3. Install the new rotor and secure it with retaining screws or clips.
4. Tighten screws to manufacturer specifications using a torque wrench.

5. Reassemble Components

Tools Required: Torque wrench, socket set
Sub-steps:
1. Reposition the caliper over the new pads and rotor.
2. Reinstall the caliper bolts and tighten to the manufacturer’s torque specifications.
3. Place the wheel back on the hub and hand-tighten lug nuts.

6. Lower Vehicle and Test

Tools Required: None
Sub-steps:
1. Lower the vehicle from the jack stands.
2. Tighten lug nuts in a crisscross pattern with a torque wrench to ensure even pressure.
3. Press the brake pedal several times to ensure proper brake pad seating.
