The idea being tested is that you don’t always have to remove the caliper to replace the brake pads. With fixed calipers, the pads are held in slots and can often be accessed from the caliper’s outside edges. After you retract the pistons to make space, you can disengage the pad retainers and slide the worn pads out and the new ones in while the caliper remains bolted to the mounting bracket. This is possible because the caliper is rigidly mounted and the pad retention is designed to allow pad changes without taking the caliper off.

Of course, there are situations where removing the caliper is still necessary—if space is too tight, if the pads are seized, or if you need to service or inspect the rotor and caliper hardware more thoroughly. But the fact remains that, in many fixed caliper designs, pad replacement can be done without removing the caliper.
