Solution

1. Preparation

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

2. Inspect and Top Off Brake Fluid

Open the hood and locate the brake master cylinder.
Check the brake fluid level; add fluid if necessary, using DOT 3 or DOT 4 brake fluid as specified in the owner's manual.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench for bleeder screws, brake fluid.
Begin with the wheel furthest from the master cylinder (usually the right rear).
1. Remove the wheel.
2. Locate the brake caliper and the bleeder screw.
3. Attach the brake bleeder kit to the bleeder screw.
4. Have an assistant pump the brake pedal several times and hold it down.
5. Open the bleeder screw to release air and brake fluid, then close it before the assistant releases the pedal.
6. Repeat until no air bubbles are present in the fluid.
7. Move to the next wheel (left rear, right front, left front) and repeat the bleeding process.
Check and top off the brake fluid after bleeding each wheel.

4. Inspect Brake Components

Reinspect the brake pads and calipers.
Ensure pads are correctly positioned and calipers are not binding.
Reassemble the wheel and torque lug nuts to the manufacturer's specifications.
