Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves for protection.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level; if low, top off with the recommended DOT fluid (usually DOT 3 or DOT 4).
3. If the fluid is discolored, consider flushing the brake system.

3. Bleed the Brake System

Sub-steps:
1. Start at the furthest brake from the master cylinder (usually the right rear).
2. Attach a clear plastic hose to the bleeder valve on the brake caliper, placing the other end in a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid; close it once fluid flows without bubbles.
5. Repeat this process for each brake, moving closer to the master cylinder (right rear, left rear, right front, left front).
6. Check the brake fluid level in the master cylinder during the process and refill as necessary.

4. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if worn below 3mm.
3. Check rotors for scoring or warping; machine or replace if necessary.
4. Reassemble the wheel and lower the vehicle.
