Yep, pretty much same experience I've had, Bobbo, as noted in previous post. NSA seems to have their spring, actuator designed (at least on the newer units) with enough resistance in it to prevent this from happening.
However, based on Scott's experience (original poster), it may be that a diesel exhaust brake does enough braking to cause the actuator to engage in some circumstances. Like he said, though, that isn't necessarily a bad thing, just a matter of personal preference.
You and I both have gassers and don't use an exhaust brake, and it seems in that case the RB actuator does not engage unless/until brake pedal is pushed.
With ANY system that presses the car's brake pedal, I recommend a dash indicator light hooked to the car's brake lights............
There are 5 wires, 1 of which is unused (87a, Normally Closed). Two wires (85 and 86) hook to the car's brake light hot wire and the car's ground. Two wires (30 and 87, Normally Open) are carried out to the front of the car and a jumper wire carries them to the Ready Brake dash indicator light.
Yep, I agree, and did same thing on mine (although not using same components). Prefer to know when brake pedal is actually being pushed, not when RB actuator is moving.
Readybrake actually used to instruct you to wire it that way, but changed it when so many folks started disconnecting battery, fuses on toad vehicle, making that approach a bit complicated in some cases.
