Final answer:
The maximum pad taper allowed before replacement is required for disc brakes depends on the specific brake system and the manufacturer's recommendations. Generally, it is recommended to replace the brake pads when the taper exceeds 0.5mm.
Step-by-step explanation:

Pad taper refers to the uneven wear pattern that occurs on the braking surface of the disc brake pads. Over time, as the pads wear down, they can develop a tapered shape where one end is thicker than the other. This can lead to reduced braking performance and uneven wear on the brake rotor.
To visually inspect for pad taper, you can remove the brake caliper and examine the brake pads from the side. If you notice a significant difference in thickness between the leading and trailing edges of the pads, it may be necessary to replace them.
