Solution

1. Preparation

Gather tools and materials:
- Brake fluid (DOT 3 or DOT 4, as specified)
- Brake bleeder kit
- Brake line wrench
- Jack and jack stands
- Safety goggles and gloves
Ensure vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Top Off Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
3. If low, add the correct type of brake fluid to the reservoir.

3. Check for Leaks

Sub-steps:
1. Inspect all brake lines, calipers, and connections for signs of leakage.
2. If leaks are found, clean the area and replace damaged components as necessary.
3. Tighten any loose connections to prevent further leaks.

4. Bleed the Brakes

Sub-steps:
1. Attach a brake bleeder kit to the bleeder screw on each brake caliper, starting from the farthest wheel from the master cylinder (usually the right rear).
2. Have an assistant press the brake pedal and hold it down.
3. Open the bleeder screw until brake fluid flows out, then close it before the assistant releases the pedal.
4. Repeat until no air bubbles appear in the fluid, then move to the next wheel.
5. Ensure the brake fluid reservoir does not run dry during this process.

5. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if they are below the minimum thickness.
3. Check rotors for grooves or warping; replace or resurface if necessary.
4. Reassemble components and torque wheel lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
