Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and turn off the ignition.
Wear safety gloves and goggles for protection.

2. Check and Refill Brake Fluid

Tools Required: Clean rag, funnel.
Inspect the brake fluid reservoir; if the fluid is low, clean the area around the cap to prevent contamination, and remove the cap.
Using a funnel, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) to the recommended level.
Replace the cap securely and clean any spilled fluid.

3. Inspect and Replace Brake Pads

Tools Required: Jack and jack stands, lug wrench, socket set, brake pad spreader.
Loosen the lug nuts on the front or rear wheels where pads need inspection.
Raise the vehicle with a jack and secure on jack stands.
Remove the wheel and inspect the brake pads for thickness; if less than 3 mm, replace them.
To replace, remove the caliper bolts, slide the caliper off, and replace the old pads with new ones.
Reassemble the caliper and wheel, ensuring all nuts are torqued to specifications (typically around 80-100 lb-ft).

4. Repair or Replace Brake Lines

Tools Required: Brake line tool kit, wrenches.
Visually inspect all brake lines for leaks or damage.
If leaks are found, replace the affected sections of the brake line using the appropriate fittings and tools.
Bleed the brake system after repairs to remove air from the lines.

5. Test the Brake System

Tools Required: Multimeter.
Reconnect any electrical connectors you may have disconnected during inspection.
Turn on the ignition without starting the engine, and check that the brake warning light is off.
Start the vehicle and press the brake pedal to ensure it feels firm and responsive.
