Can new pads and rotors be recommended without ever taking off the wheels?

Dear Car Talk | Feb 01, 1996
Dear Tom and Ray:
Bill
TOM: Yes, it is. You CAN see the pads and rotors on a lot of cars without taking the wheels off. And you can usually tell if the pads are worn out or the rotors are chewed and pitted.
RAY: There are things you probably won't be able to see without removing the wheels--like a brake fluid leak or a seized caliper piston. But if they're just looking at pads and rotors, the answer is yes, they can tell.
TOM: But I definitely understand your skepticism, Bill. My brother used to tell customers that they needed a new transmission after simply laying his hands on the car's hood. If I remember correctly, it was the Attorney General who made him cut that out.
