Solution

1. Preparation

Gather tools and materials: brake cleaner, socket set, torque wrench, and jack stands.
Ensure the vehicle is parked on a level surface, the ignition is off, and the parking brake is engaged.
Safety Warning: Always wear safety glasses and gloves when handling brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the brake caliper.
3. Unbolt the brake caliper using the socket set and remove it from the rotor.
4. Inspect brake pads for uneven wear; replace if necessary with OEM or quality aftermarket pads.
5. Reinstall the caliper and wheel, tightening bolts to manufacturer specifications.

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. Remove the brake rotor after taking off the caliper and pads.
2. Measure rotor thickness; if below specifications or warped, resurface or replace.
3. Clean the rotor surface with brake cleaner before reinstalling.
4. Reinstall the rotor and brake caliper, making sure all components are properly secured.

4. Brake Fluid Check and Replacement

Sub-steps:
1. Open the master cylinder reservoir cap and check the fluid level.
2. If the fluid is low or contaminated, perform a brake fluid flush.
3. Use a brake bleeder kit to ensure all air is removed from the lines.
4. Refill the master cylinder with new, manufacturer-recommended brake fluid.

5. Final Assembly and Testing

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Tighten lug nuts to the specified torque.
3. Test the brake pedal for firmness before driving.
4. Perform a short test drive to check for brake performance and any remaining issues.
