Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Take off the brake caliper by removing the caliper bolts (usually 13-15mm).
3. Slide the caliper off the rotor and hang it with a bungee cord to avoid stress on the brake line.
4. Remove old brake pads from the caliper bracket.
5. Inspect the brake pad backing plates; replace if worn down to the indicator.
6. Install new brake pads, ensuring they are properly aligned.
7. Re-install the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the thickness of the rotors; replace if below the minimum specification.
2. If warped or damaged, remove the rotor by unscrewing the rotor retaining screws (if applicable).
3. Install new rotors, ensuring they are clean and free from oil.
4. Torque the rotor screws to the specified torque value.

4. Bleed the Brake System

Sub-steps:
1. Reconnect the negative battery terminal.
2. To bleed the brakes, start at the wheel farthest from the master cylinder (usually the rear passenger side).
3. Use a brake bleeder kit to ensure no air is trapped in the lines.
4. Repeat for the other wheels in the proper sequence (rear passenger, rear driver, front passenger, front driver).
5. Check the brake fluid level and top off as necessary.
