Question:
What is a modulating control valve?
A
A control handle used to apply the spring brakes gradually.
explanation
A modulating valve is spring-loaded so you have a
feel for the braking action. The more you move the
control lever, the harder the spring brakes come on.
They work this way so you can control the spring
brakes if the service brakes fail.

I like the idea of the app. It would be great if a user could switch to Dyslexia mode for people with Dyslexia so we can understand it better and retain more. As I have to re read a lot of it over. From what I understand it's basically a font change if im not mistaken. Just a thought. Thanks 😊 Eddie J.
