Solution

1. Preparation

Tools Required: Floor jack, jack stands, socket set, brake bleeder kit, brake fluid (DOT 4 or manufacturer recommended).
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Fluid

Check Brake Fluid Level:
- Open the master cylinder reservoir cap and check the fluid level.
- If low, top up with fresh brake fluid of the specified type.
Inspect for Contamination:
- If the fluid is dark or contaminated, replace it.
Flush the Brake System:
- Use a brake bleeder kit to flush out old fluid, ensuring that fresh fluid is introduced in all lines.

3. Brake Line Inspection and Repairs

Visual Inspection:
- Check all brake lines for signs of wear, corrosion, or leaks.
- Pay special attention to fittings and connections.
Replace Damaged Lines:
- If any leaks or damages are found, replace the affected brake lines with new ones.

4. Brake Component Inspection

Remove Wheel:
- Use a floor jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Inspect Brake Pads and Rotors:
- Examine the brake pads for thickness; replace if worn below the manufacturer specification.
- Check rotors for warping or scoring and replace if necessary.

5. Bleed the Brake System

Locate Bleed Valves:
- Find the bleed valves on each brake caliper.
Bleeding Procedure:
- Have an assistant pump the brake pedal to build pressure.
- Open the bleed valve and allow fluid to escape until no air bubbles are present. Close the valve before releasing the pedal.
- Repeat for all wheels until the brake pedal feels firm.
