Solution

1. Preparation

Gather tools and parts: Ensure you have a socket set, brake fluid, and a brake bleeder kit.
Make sure the vehicle is on a level surface and safely secured with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Refill Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir cap.
2. Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4 as specified).
3. Inspect the fluid for contamination (cloudiness or dark color).

3. Bleed Brakes

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually 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.
4. Close the valve before your assistant releases the pedal.
5. Repeat until no air bubbles are present in the fluid.
6. Move to the next wheel in the order: rear driver side, front passenger side, and finally front driver side.

4. Inspect and Replace Components (if necessary)

Sub-steps:
1. Remove the wheel to access brake components.
2. Check the brake pads for thickness; replace if less than 3mm.
3. Inspect rotors for warping or scoring; replace if necessary.
4. Replace any damaged brake lines or hoses.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer's specification.
2. Reconnect the battery and start the vehicle.
3. Press the brake pedal to ensure it feels firm before driving.
