Summary of Issue

Clarification is requested relative to the revised "NOTE:" under Part II, Item 1. Brake System b. Front Steering Axle(s) Brakes (2)(a).

What guidance is used, or how do you determine if the brake chambers are mismatched, if the vehicle is equipped with a type 20 clamp chamber and a bolt type chamber when the bolt type chambers are classified in an alphabetical type rating?
