I'm not a fan of the Ready Brake system, but I've installed a couple of them for friends. I think they're a good choice for a light or moderate weight vehicle. I also believe they need the air pump to keep from pulling on a dead pedal.
"willald"....made a point that I was thinking while reading through this thread. Even though you may not be mechanically inclined or physically able to install something like a supplemental brake system, you need to speak to the installer and understand the nuances of connecting/adjusting it. Especially a product like the Ready Brake that has a cable that sits loosely above moving mechanisms.
