Solution

1. Preparation

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

2. Brake Fluid Inspection

Step 1: Open the hood and locate the brake fluid reservoir.
Step 2: Check the fluid level; if low, fill it with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
Tools Required: Brake fluid.

3. Bleed the Brake System

Step 1: Start by removing the brake fluid reservoir cap.
Step 2: Use a brake bleeder kit or a clear plastic tube attached to the bleeder valve on the brake calipers.
Step 3: Have an assistant pump the brake pedal several times and hold it down.
Step 4: Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
Step 5: Repeat this process until no air bubbles are present in the fluid.
Tools Required: Brake bleeder kit, clear plastic tubing.

4. Inspect and Replace Brake Components

Step 1: Remove the wheel to access the brake caliper and rotor.
Step 2: Inspect brake pads for wear; if they are worn down to the indicator, replace them.
Step 3: Check the rotor for grooves or warps; if damaged, replace the rotor.
Step 4: If necessary, replace with new brake pads and rotors according to manufacturer specifications.
Tools Required: Socket set, torque wrench, brake cleaner.

5. Reassemble and Test

Step 1: Reinstall the wheel and lower the vehicle.
Step 2: Test the brake pedal feel before driving; it should feel firm.
Step 3: Conduct a test drive to ensure proper braking performance.
