Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir (typically near the back of the engine bay).
Remove the cap and check the fluid level.
If low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, new brake pads.
Loosen the lug nuts and raise the vehicle using a jack. Secure with jack stands.
Remove the wheel to access the brake caliper.
Unbolt the caliper and remove it from the rotor.
Inspect the brake pads; if worn down to the indicators, replace them.
Clean the caliper and rotor surfaces with brake cleaner before installation.
Install new brake pads, ensuring they are seated properly.
Reassemble the caliper and wheel, and torque the lug nuts to the manufacturer’s specifications.

4. Inspect Brake Lines and Components

Tools Required: Visual inspection tools, flashlight.
Examine all brake lines for signs of wear, corrosion, or leaks.
Check for any loose connections or damaged fittings.
Replace any damaged brake lines or components as necessary.

5. Test the Brake System

After repairs, pump the brake pedal several times to build pressure.
Check for leaks around the brake lines and fittings.
Test drive the vehicle at low speeds to ensure proper braking function.
