Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Locate and remove the caliper mounting bolts using a socket set.
3. Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stressing the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads in the caliper bracket, ensuring they are properly aligned.

3. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
1. Check the thickness of the rotors with a micrometer; replace if below the minimum specification.
2. If replacing, remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
3. Install the new rotor, ensuring it fits snugly against the hub.

4. Bleed the Brake System

Sub-steps:
1. Refill the master cylinder with fresh brake fluid as recommended by the manufacturer.
2. Use a brake bleeder kit to remove air from the brake lines, starting from the wheel farthest from the master cylinder (usually the right rear).
3. Repeat the process for each wheel, ensuring fluid flows without bubbles.

5. Reassemble and Test

Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with the mounting bolts, tightening to the manufacturer's torque specifications.
2. Reinstall the wheel and tighten lug nuts in a star pattern to avoid warping.
3. Reconnect the battery and take the vehicle for a test drive to ensure proper brake function.
