2. Locate the Leak

Inspect Brake Lines:
- Use a flashlight to examine the entire length of the brake lines for leaks.
- If a leak is detected, mark the area for repair or replacement.
Inspect Brake Calipers:
- Check the calipers for wetness or fluid residue.
- If leaking, proceed to replace the caliper.

3. Repair or Replace Affected Components

Replace Brake Lines:
- Remove any brackets or clips holding the damaged brake line.
- Use a line wrench to disconnect the line from the master cylinder and caliper.
- Install the new brake line, ensuring it follows the original routing.
- Torque connections to manufacturer's specifications.
Replace Brake Caliper:
- Remove the wheel and brake assembly.
- Unbolt the caliper and disconnect the brake line.
- Install the new caliper and reconnect the brake line.
- Torque to manufacturer's specifications.
Replace Master Cylinder (if necessary):
- Remove the brake lines from the master cylinder.
- Unbolt the master cylinder from the brake booster.
- Install the new master cylinder and reconnect brake lines.
- Torque to manufacturer specifications.

4. Refill and Bleed the Brake System

Refill Brake Fluid:
- Fill the brake fluid reservoir with the appropriate type of brake fluid.
Bleed Brakes:
- Start at the wheel furthest from the master cylinder and work toward the nearest.
- Use a bleeder kit or have an assistant pump the brake pedal while you open the bleeder valve to release air.
- Close the valve before the pedal is fully depressed to prevent drawing air back in.
