With normal driving, how long will the OE brake pads and rotors last on the car? I have 48K on the car, and am not sure if they were replaced already since I have had the car only for about 10K miles.

It depends on what 'normal' is for you. My wife drives her SUV 50 miles each way commuting to work. It is mostly highway, and the original pads are still good at 108,000 miles.

Routine maintenance on a car should include checking the brake pad thickness every 12,000 miles. The brake caliper has a slot to view the outer pad, and the inner pad is visible from the side. The pad should be replaced when the thickness is less than 1.5-2mm.
