Solution

1. Preparation

Gather tools: brake fluid, socket set, wrench set, brake bleeder kit, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Brake Fluid

Remove the master cylinder cap and inspect the brake fluid level.
If low, add the manufacturer-recommended brake fluid type (e.g., DOT 3 or DOT 4).
If contaminated (dark or cloudy), proceed to replace the fluid.

3. Bleed the Brake System

Start with the wheel farthest from the master cylinder (right rear).
Attach a brake bleeder kit to the bleeder valve on the brake caliper.
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 for all wheels in the following order: right rear, left rear, right front, left front.

4. Inspect and Replace Brake Components (if necessary)

Remove the wheel to access the brake caliper.
Inspect brake pads for wear; replace if less than 3 mm thick.
Check rotors for warping or scoring; replace if necessary.
Reassemble the brake caliper and wheel, torque lug nuts to specified values.
