Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the battery to prevent electrical issues during inspection.

2. Check Brake Fluid Level

Locate the brake fluid reservoir, usually found near the driver's side of the engine bay.
Remove the cap and check the fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4, as specified in the owner’s manual).

3. Inspect Brake Pads

Remove the front and rear wheels using a socket set.
Visually inspect brake pads for wear; replace if the thickness is below 3 mm.
Ensure that the brake pads are seated properly in the caliper.

4. Inspect Brake Lines and Hoses

Examine all brake lines and hoses for signs of leaks, bulges, or corrosion.
Replace any damaged or leaking hoses with OEM or high-quality aftermarket parts.

5. Check the Master Cylinder

Inspect the master cylinder for fluid leaks.
If leaks are present, replace the master cylinder and bleed the brake system to remove air.
Use a torque wrench to ensure the mounting bolts are tightened to the manufacturer’s specifications.

6. Test Drive and Recheck

Reconnect the battery and start the vehicle.
Perform a test drive to ensure the brakes function properly without warning lights reappearing.
