I hear whistling/scratching noise when the car is moving.
Nawawala when I step on the brakes or the car is not moving.

Also I notice minsan naiipit yung brakes. When I'm hanging on an incline I don't roll even though the handbrake is not engaged. I have to step fully on the brakes to fix this.

Malakas naman ang brakes and puno lalagyan ng brake fluid.

Car is an ES civic.
Help naman mga peeps.
