Solution

1. Preparation

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

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Identify the Leak

Tools Required: None
Sub-steps:
1. Clean any brake dust or debris around the brake components.
2. Visually inspect the brake lines, calipers, master cylinder, and wheel cylinders for the source of the leak.

4. Repair the Leak

Tools Required: Wrenches, brake line flaring tool (if applicable)
Sub-steps:
1. If the leak is from a brake line, cut out the damaged section and replace it with a new line. Flare the ends as needed.
2. For leaking calipers or wheel cylinders, remove the affected component, replace any seals or gaskets, or replace the entire unit if necessary.
3. If the master cylinder is leaking, unbolt it from the brake booster and install the new master cylinder.

5. Refill and Bleed the Brake System

Tools Required: Brake fluid, bleed kit or clear tubing
Sub-steps:
1. Refill the brake fluid reservoir with the manufacturer-recommended brake fluid.
2. Begin bleeding the brakes starting from the furthest wheel from the master cylinder (usually the rear passenger side), ensuring no air remains in the lines.
3. Repeat until all wheels have been bled and the brake pedal feels firm.

6. Reinstall the Wheel

Tools Required: Lug wrench, jack
Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
