Hey all,
I've recently purchased my '82 GMC and it has an add-on traler brake controler and I notice it has a brake line plumbed into it. This runs from a tee in one of the lines off the master cylinder, through the firewall, and into the controller. I haven't found a brand name yet, but it's very apparent that it is a "vintage" unit. It even has faux wood grain IIRC.
I assume it is there to sense when pressure is applied to the brake system so that it can activate trailer brakes. This assumption may or may not be accurate though.
Can anybody comment on weather or not this is a desirable feature, or an outdated one. I'm a little leary of having accessories plumbed into the brake system, but if it's a good old controller, I'll give it a whirl.
Thanks,
Clem
