Solution

1. Preparation

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

2. Inspect and Fill Brake Fluid

Locate the brake fluid reservoir.
Check the fluid level; if low, fill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Inspect the brake lines for any visible leaks or damage.

3. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench for bleeder screws
Starting with the wheel farthest from the master cylinder (usually the right rear):
1. Attach the brake bleeder kit to the bleeder screw.
2. Have an assistant pump the brake pedal several times and hold it.
3. Open the bleeder screw to release air and fluid, then close it while your assistant keeps the pedal pressed.
4. Repeat until no air bubbles are present in the fluid flowing out.
5. Move to the next wheel and repeat the process (left rear, right front, left front).

4. Inspect and Replace Brake Components (if necessary)

Check brake pads and rotors for excessive wear.
If pads are worn down or rotors are scored, replace them.
- Tools Required: Socket set, torque wrench
- Remove the wheel and caliper assembly.
- Replace pads or rotors as needed, ensuring proper alignment.
- Reassemble and torque bolts to manufacturer specifications.

5. Final Checks

Refill the brake fluid reservoir to the appropriate level.
Test the brake pedal feel before taking the vehicle on the road.
