Solution

1. Preparation

Gather tools and replacement parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set (typically a 21mm socket).
2. Remove the caliper bolts and slide the caliper off the rotor.
3. Inspect the brake pads for wear; replace if less than 3mm thick.
4. Install new brake pads by sliding them into the caliper bracket.
5. Reattach the caliper and tighten bolts to the manufacturer's torque specification (usually around 23-30 lb-ft).
6. Repeat for all wheels as necessary.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. If rotors are warped or scored, remove the caliper and pads as previously described.
2. Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install new rotors, ensuring they are clean and free of grease.
4. Reinstall caliper and pads as previously instructed.
5. Torque all components to specification.

4. Check Brake Fluid System

Sub-steps:
1. Check brake fluid level and quality in the master cylinder.
2. If fluid is dirty or low, flush the brake system using a brake fluid bleeder.
3. Replace brake fluid with the recommended type (typically DOT 3 or DOT 4).
4. Bleed each brake line starting from the furthest wheel to the closest (right rear, left rear, right front, left front).
