Solution

1. Preparation

Gather tools and materials:
- Brake fluid (DOT 4 or as specified for your model)
- Wrench for bleeder screws (typically 8mm or 10mm)
- Clear plastic tubing
- Catch container for old brake fluid
- Brake pedal pump helper (if available)
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety goggles and gloves for protection.

2. Locate Brake Bleeder Screws

Identify the brake bleeder screws on each brake caliper:
- Front calipers usually have them on the top side.
- Rear calipers may have them on the top or side.

3. Bleed the Brakes

1. Starting with the furthest wheel from the master cylinder (right rear):
- Attach the clear tubing to the bleeder screw and place the other end in the catch container.
- Open the bleeder screw slightly using the wrench.
- Ask an assistant to pump the brake pedal several times and hold it down.
- While the pedal is held down, tighten the bleeder screw to prevent air from entering.
- Release the pedal slowly and check for air bubbles in the tubing. Repeat until no more air bubbles are present.
- Tighten the bleeder screw securely after bleeding.
2. Repeat for each wheel in the following order:
- Right rear
- Left rear
- Right front
- Left front

4. Final Steps

Refill the master cylinder reservoir with new brake fluid as needed throughout the bleeding process.
Ensure all bleeder screws are tight and clean any spilled brake fluid from the components.
Check the brake pedal feel; it should be firm.
