It's connected to the bottom of the master cylinder, so obviously it has something to do with the brakes...but what? It definitely looks like an aftermarket item... Thanks, in advance!! | | | | | Joined: Mar 2001 Posts: 259 Member | | Member Joined: Mar 2001 Posts: 259 | Its a brake lock unit. I use to have one on my old Dodge truck.

The units for older bigger trucks are actuated by a line that runs from the brake line into the unit and then sends an electrical signal back to the trailer brakes electrically.

The newer ones are inertial, and don't have the hydraulic line attached. It's for controlling electric brakes on a travel trailer, etc. If you try to use the control unit with the hydraulic line attached on an anti-lock brake system, it will disable the anti-lock feature. The hand knob is used to apply the trailer brakes only, without using the tow vehicle brakes, a good feature for dampening out a sway, etc.

Thanks again for the expert feedback... By the way...what happened to "The Lounge"? I don't see it anymore?? | | | | | Joined: May 2001 Posts: 477 Shop Shark | | Shop Shark Joined: May 2001 Posts: 477 | it went away. guess we leave it at that. back to the subject. you might think before you do away with the controller. i understand about the original equipment thing, but if you ever do pull a trailer those things are real handy. a trailer that's loaded too far back can sway and cause you to jacknife. that button is a damned good way to save your truck, or your life. just think about it. maybe you can hide it better, but still be able to use it. | | | | | Joined: Apr 2000 Posts: 179 Shop Shark | | Shop Shark Joined: Apr 2000 Posts: 179 | I just put one like that on my '77 C-30. One panic stop with a loaded trailer was enough to motivate to get it hooked up.
