after removing the brake pads, hang the caliper by its brake hose.
true
false

Explanation:

First Question (Caliper Interchange)

Brake calipers have pistons that move in opposite directions for left and right sides (to apply force to the brake disc). Interchanging them would disrupt this directional movement, affecting braking. Other options: reversing shoes isn't the main issue, dust boot sealing is less critical, and bleeder valve position is not the primary reason. So the correct reason is pistons move in opposite directions.

Technician A: Cracks in brake pad lining can compromise safety, so replacement is correct. Technician B: Brake performance complaints (like noise, reduced braking) warrant inspecting pads, so this is also correct. Thus both are right.

Hanging a caliper by its brake hose can damage the hose or cause fluid leaks, as the hose isn't designed to support the caliper's weight. So the statement is false.

Answer:

D. Pistons move in opposite directions
