Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Tools and Materials

Brake fluid (DOT 4)
Brake bleeder kit or clear tubing
8mm wrench (for bleeder screws)
Torque wrench
Clean rags
Safety glasses and gloves

3. Locate Brake Bleeder Screws

Identify the brake bleeder screws located on each brake caliper. The order of bleeding typically starts from the brake farthest from the master cylinder (right rear, left rear, right front, left front).

4. Bleeding Process

Fill Reservoir:
- Open the brake fluid reservoir cap and fill it with fresh brake fluid to the maximum level.
Bleed the Brakes:
- Attach the clear tubing to the bleeder screw and place the other end into a container to collect the expelled fluid.
- Use the 8mm wrench to open the bleeder screw slightly (about a quarter turn).
- Instruct an assistant to press the brake pedal slowly and firmly.
- Watch for the fluid and air bubbles to flow through the tubing. Once the pedal is fully depressed, close the bleeder screw before they release the pedal.
- Repeat this process until only clear brake fluid (without air bubbles) is seen in the tubing.
- Check the brake fluid level in the reservoir frequently, and top off as needed to prevent the master cylinder from running dry.
Repeat:
- Repeat the bleeding process for all four wheels in the recommended order.

5. Final Steps

After bleeding all brakes, ensure that all bleeder screws are securely tightened.
Refill the brake fluid reservoir to the maximum level and replace the cap.
Lower the vehicle from the jack stands.
