Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Engage the parking brake for safety.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Verify the brake fluid level in the master cylinder reservoir.
If low, add the recommended brake fluid type (DOT 3 or DOT 4) until it reaches the "Full" mark.
Safety Warning: Always use the recommended brake fluid type; using the wrong fluid can damage the braking system.

3. Replace Worn Brake Pads and Rotors (if necessary)

Tools Required: Jack and jack stands, socket set, brake cleaner, torque wrench
Lift the vehicle and remove the wheels using a jack and socket set.
Remove the caliper by unbolting it and suspend it using a wire to avoid tension on the brake line.
Take out the old brake pads and inspect the rotors for wear. Replace them if they are below the minimum thickness.
Clean the rotor surface with brake cleaner before installing new pads.
Install new brake pads and reassemble the caliper, ensuring bolts are torqued to the manufacturer's specifications.

4. Repair or Replace Damaged Brake Lines

Tools Required: Brake line wrench, brake line kit (if replacement is needed)
Inspect all brake lines for leaks or damage.
If any lines are damaged, replace them by disconnecting at the fittings and using the new brake line kit.
Bleed the brake system to remove any air trapped in the lines after replacement.

5. Check ABS Module

Tools Required: OBD-II scanner
If the ABS warning light is also on, use the OBD-II scanner to check for ABS-related codes.
Follow the manufacturer’s guidelines to address any potential faults indicated by the scanner.
