Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is in a secure location with the engine off.
Wear safety glasses and gloves.

2. Check and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the brake fluid level; it should be between the minimum and maximum marks.
3. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
4. If the fluid is dark or contaminated, proceed to flush the brake system.

3. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Attach a clear tube to the bleeder valve on the brake caliper and place the other end in a container to catch fluid.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
5. Repeat until no air bubbles appear in the fluid. Move to the next wheel, following the order: right rear, left rear, right front, left front.
6. Ensure the brake fluid reservoir does not run dry during this process.

4. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads and rotors for wear; replace if they are below the minimum thickness.
3. If brake pads are worn, remove the caliper (using a socket set) and replace with new pads.
4. Check the caliper for proper operation; replace if it’s sticking or leaking.
5. Reassemble the brakes, ensuring all bolts are torqued to manufacturer specifications.

5. Test Drive

Sub-steps:
1. After reassembling, pump the brake pedal to restore pressure.
2. Lower the vehicle and perform a test drive in a safe area to ensure brakes operate correctly.
