Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and disconnect the battery for safety.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
Remove the master cylinder cap and check the brake fluid quality; if it appears dark or contaminated, replace it.
Use a funnel to add the recommended brake fluid type (usually DOT 3 or DOT 4) until it reaches the proper level.
Wipe any spilled fluid with a clean cloth, ensuring that no contaminants enter the reservoir.

3. Check and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set
Loosen the lug nuts and raise the vehicle with a jack, securing it on jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace them if they are worn down to 3mm or less.
Remove the caliper bolts and slide the caliper off the rotor. Replace the pads and reassemble the caliper.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
Locate the brake bleeder valves on each brake caliper.
Attach clear tubing to the bleeder valve and submerge the other end in a container filled with brake fluid.
Have an assistant pump the brake pedal several times and hold it down. Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal. Repeat until no air bubbles appear in the fluid.
Ensure the master cylinder reservoir remains filled during the process.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery and start the engine.
Test the brake pedal feel and check for any leaks around the brake components.
