Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Jack up the vehicle and secure it with jack stands.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the wheel is still on the ground.
2. Lift the vehicle with a jack and secure with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or similar to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of leakage or damage.
5. Install new brake pads in the caliper bracket ensuring they are positioned correctly.
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or damaged, remove them by unbolting from the hub.
2. Clean the hub surface to ensure a smooth mounting for the new rotor.
3. Install new rotors, ensuring they are properly seated.
Tools Required: Socket set, brake cleaner.

5. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten caliper bolts to manufacturer specifications using a torque wrench.
3. Reinstall the wheel and tighten lug nuts in a crisscross pattern for even pressure.
Tools Required: Torque wrench.

6. Final Checks

Lower the vehicle back to the ground.
Pump the brake pedal several times to seat the brake pads properly against the rotors.
