Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift Vehicle

Tools Required: Jack and jack stands
Safely lift the front or rear of the vehicle using a jack and secure it with jack stands.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Unbolt and remove the brake caliper; hang it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
4. Install the new rotor, ensuring it is flush against the hub.
5. Reattach the brake caliper over the new rotor.
Tools Required: Socket set, torque wrench
Safety Warning: Ensure the brake system is not under pressure before removing components.

4. Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a brake caliper tool to create space for the new pads.
3. Install new brake pads into the caliper bracket ensuring proper alignment.
Tools Required: Brake caliper tool, socket set
Safety Warning: Avoid touching the brake pad surface with bare hands to prevent contamination.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and firmly set it on the ground.
