Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel, rags
Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; if low, top it up with the recommended brake fluid type (DOT 3 or DOT 4).
Clean any spilled brake fluid immediately, as it can damage vehicle paint.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench, clear tubing
Start at the wheel farthest from the master cylinder (usually the rear passenger side).
Attach the clear tubing to the bleeder valve on the brake caliper and place the other end in a container.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat this process until no air bubbles appear in the fluid (typically 3-5 times per wheel).
Move to the next wheel in order: rear driver side, front passenger side, and finally front driver side.

4. Inspect Brake Components

Tools Required: Jack, jack stands, lug wrench, socket set
Safely lift and support the vehicle with jack stands.
Remove the wheel using the lug wrench.
Inspect brake pads; replace if thickness is below 3mm or if they show uneven wear.
Check rotors for scoring or excessive wear; replace if necessary.

5. Final Assembly

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Lower the vehicle and ensure all tools are removed from the work area.
