Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brake system.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the cap from the brake fluid reservoir.
2. Inspect the fluid for contamination or low levels; top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is contaminated, proceed to flush the system.
Tools Required: Brake fluid, funnel, rags.

3. Bleed the Brake Lines

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually rear passenger side).
2. Loosen the bleeder valve on the brake caliper with a wrench.
3. Ask an assistant to pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air; close it before the pedal is released.
5. Repeat until no air bubbles are seen, then tighten the valve.
6. Move to the next wheel and repeat the process until all four brakes are bled.
Tools Required: Brake bleeder wrench, clear tubing, container for old fluid.

4. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear; replace if less than 3mm thick.
3. Check rotors for scoring or warping; replace if necessary.
4. Reassemble the wheel and lower the vehicle.
Tools Required: Socket set, torque wrench, brake pads, rotors (if replacement needed).
