1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the battery to prevent electrical issues.

2. Identify and Repair Leak

Brake Lines/Hoses:
- Tools Required: Wrench set, line wrenches
- Instructions:
  1. Locate the section of brake line or hose that is leaking.
  2. If a brake line is damaged, use a line wrench to disconnect it from the fitting.
  3. Replace the damaged section with a new brake line or hose, ensuring all fittings are tight and secure.
  4. If hose clamps are used, replace them if they are damaged.
Brake Calipers/Wheel Cylinders:
- Tools Required: Socket set, torque wrench
- Instructions:
  1. Remove the wheel to access the brake caliper.
  2. Inspect the caliper for fluid leakage around the piston or seals.
  3. If leaking, remove the caliper and rebuild it with a new seal kit or replace it with a new caliper.
  4. Reinstall the caliper and torque bolts to manufacturer specifications.
Master Cylinder:
- Tools Required: Wrench set, brake fluid, rags
- Instructions:
  1. Locate the master cylinder and check for leaks around the base.
  2. If leaking, remove the master cylinder from the brake booster by unbolting it.
  3. Replace it with a new master cylinder and bleed the braking system after installation.

3. Refill and Bleed Brake System

Tools Required: Brake bleeder kit, brake fluid
Instructions:
1. Refill brake fluid reservoir with the recommended fluid type.
2. Use the brake bleeder kit to bleed each brake line starting from the farthest wheel to the closest to remove air from the system.
3. Ensure the brake pedal feels firm before replacing the wheels.
