Solution

1. Preparation

Gather tools and materials:
- Brake fluid (DOT 3 or as specified)
- Wrenches and sockets
- Brake bleeder kit
- Rags and cleaning supplies
Ensure the vehicle is parked on a level surface and turn off the ignition.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder reservoir.
2. Remove the cap and visually inspect the brake fluid for contamination (cloudy or dark).
3. If fluid is contaminated, use a turkey baster to remove old fluid from the reservoir.
4. Refill with fresh brake fluid to the recommended level.

3. Bleed the Brakes

Sub-steps:
1. Start at the brake furthest from the master cylinder (usually the rear passenger side).
2. Attach the brake bleeder kit to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air and fluid.
4. Close the valve before your assistant releases the brake pedal.
5. Repeat until no air bubbles appear in the bleeder hose; check fluid levels frequently.
6. Move to the next wheels in the order: rear driver side, front passenger side, and finally front driver side.

4. Inspect and Replace Brake Components (if necessary)

Sub-steps:
1. If symptoms persist after bleeding, inspect brake pads and rotors for wear.
2. Replace worn brake pads with new ones, ensuring proper fit and alignment.
3. If rotors are scored or below the minimum thickness, replace them.
4. Reassemble all components and torque bolts to manufacturer specifications.
