Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Inspect and Replenish Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Check the brake fluid level. If low, add the appropriate brake fluid (DOT 4).
Tools Required: Brake fluid

3. Bleed the Brakes

Sub-steps:
1. Begin with the wheel farthest from the master cylinder (usually the right rear).
2. Attach a clear tube to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, close it, and instruct the assistant to release the pedal. Repeat until clear fluid without bubbles flows out.
5. Move to the left rear, then right front, and finally left front in that order.
Tools Required: Bleeder kit, wrench for bleeder valve

4. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake caliper.
2. Inspect brake pads for thickness; replace if worn below manufacturer specifications.
3. Inspect rotors for signs of warping or excessive wear; replace if necessary.
4. Reassemble components after replacement, ensuring proper torque specifications.
