Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Check Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid level in the master cylinder reservoir. If low, top it up with the manufacturer-recommended brake fluid.
If the fluid is contaminated, proceed to replace it by bleeding the brake system.

3. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line repair kit
Check for any damaged or rusted brake lines.
If leaks are found, replace the damaged sections of the brake line using the brake line repair kit.
Ensure all connections are tight and secure.

4. Replace Brake Components if Necessary

Tools Required: Socket set, torque wrench
If brake calipers or wheel cylinders are leaking or damaged, remove them using a socket set.
Install new or refurbished calipers/wheel cylinders, ensuring to torque bolts to the manufacturer's specifications.

5. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
Connect the brake bleeder kit to the brake bleeder valve on each caliper or wheel cylinder.
Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
Repeat until clear, bubble-free fluid flows from each bleeder, then close the valves.
