Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely parked.
Wear safety goggles and gloves.

2. Add Brake Fluid

Locate the Brake Fluid Reservoir: Open the hood and locate the brake fluid reservoir.
Remove Cap: Carefully remove the reservoir cap to avoid contamination.
Add Fluid: Use the manufacturer-recommended brake fluid type (e.g., DOT 3 or DOT 4) and fill to the proper level marked on the reservoir.
Reinstall Cap: Securely replace the cap on the reservoir.

3. Inspect and Repair Brake Lines

Visual Inspection: Examine all brake lines for cracks, corrosion, or loose fittings.
Tighten or Replace: Tighten any loose fittings; if damage is found, replace the affected brake line or hose.
Bleed Brake System: If any lines were disconnected or replaced, bleed the brake system to remove air.

4. Replace Brake Pads (if necessary)

Remove Wheel: Use a jack to lift the vehicle and remove the wheel to access the brake components.
Remove Caliper: Unscrew the caliper mounting bolts and slide the caliper off the brake pads.
Replace Pads: Remove old brake pads and install new ones, ensuring proper alignment.
Reattach Caliper: Reinstall the caliper and tighten the mounting bolts to manufacturer specifications.

5. Final Checks

Test Brake Functionality: Start the vehicle and pump the brake pedal to ensure it feels firm.
Check for Leaks: Inspect the brake system for any signs of fluid leakage after the repairs.
