Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety goggles and gloves.

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Remove the master cylinder cap and inspect the brake fluid level.
If low, add the recommended brake fluid type (DOT 3 or DOT 4) until the proper level is reached.
Replace the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, container for old fluid
Starting with the wheel farthest from the master cylinder (usually the passenger side rear):
1. Attach the bleeder kit to the brake bleeder valve on the brake caliper.
2. Have an assistant press the brake pedal several times and hold it down.
3. Open the bleeder valve with a wrench to release air and old fluid.
4. Close the valve before your assistant releases the brake pedal.
5. Repeat this process for all four wheels, moving from farthest to closest to the master cylinder.
Ensure to check the fluid level in the master cylinder frequently and top off as necessary.

4. Inspect and Replace Brake Components if Necessary

Tools Required: Socket set, torque wrench, jack and jack stands
Remove the wheel to access the brake components.
Inspect brake pads and rotors for wear. Replace if pads are below 3mm thickness or if rotors are scored.
If wear is significant, remove the caliper using a socket set, replacing any necessary components.
Reassemble the brake components and torque bolts to manufacturer specifications.
