Would appreciate advice on a toad brake system

We considered a portable like the Brake Buddy early on, but after watching a few people lugging one in and out, getting on their knees to hook up the peddle arm, etc, we decided to go with a ReadyBrake permanently installed system. After the initial installation, hooking up only requires snapping a clip on an eyelet at the front of the toad. The installation itself is within the capabilities of most shade tree mechanics that can read and follow directions. The version we chose is built in to our ReadyBrute Elite tow bar, but NSA also has a stand alone version. The ReadyBrake is a simple mechanical device that works well and has none of the elecrical/electronic failure points of most of the others.

I used a brake buddy with satisfactory results. I'm waiting for the "proportional" purple koolaid drinkers to visit shortly.

Readybrake has served me well for years with no issues....

How many vehicles do you plan to tow?
Readybrake makes an excellent surge brake system. Each vehicle would need a cable installed.
