Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery (negative terminal) for safety.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean cloth
- Check the brake fluid level; if low, top it off with the appropriate type of brake fluid (usually DOT 3 or DOT 4).
- If the fluid appears dirty or contains debris, perform a complete brake fluid flush.

3. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench for bleeder screws, container for old fluid
- Locate the bleeder valves on each brake caliper (starting with the wheel farthest from the master cylinder).
- Attach the brake bleeder kit to the bleeder screw, and have an assistant pump the brake pedal several times.
- Open the bleeder screw to allow old fluid and air to escape; tighten the screw once fluid flows without bubbles.
- Repeat for each caliper in order: right rear, left rear, right front, left front.
- Ensure the brake fluid reservoir remains topped up during the bleeding process.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench
- Remove the wheel to access the brake components.
- Inspect brake pads for wear; replace if thickness is below 3 mm.
- Check rotors for damage or wear; machine or replace as necessary.
- Reassemble all components and ensure all bolts are torqued to manufacturer specifications.

5. Final Checks

Reconnect the battery.
Test the brake pedal feel again; it should be firm and responsive.
Take the vehicle for a short test drive to ensure brakes function correctly.
