For multi-caliper brakes popular for accommodating different tensions, Pelletier recommends that converters operating in the 15 psi to 20 psi range deactivate enough calipers so the brake will require 40 psi to 60 psi at full roll condition, providing similar tension results.

Pelletier advises that a brake with forced air cooling may be required for faster line speeds. A standard air-cooled brake that is squealing can be kept cooler via a fan or regulated shop air blown across the brake at 3 psi to 5psi. He also recommends seeking out good repeatability characteristics. P/A's Soft-Aire brakes can provide the same torque reading for 20 brakes at the same time using the same air pressure.
