Trouble Setting Brake Pressure on Roadmaster InvisiBrake Supplemental Braking System
Updated 04/26/2023 | Published 04/25/2023
Question:
I have a 2018 jk, I can’t get the the Invisibrake to set. I’ve pulled the knob out to set it want set at any setting. The Invisibrake comes on and vibrates when the brake away switch is activated. I just can get it to set.

Helpful Expert Reply:
I checked the instructions for the Roadmaster InvisiBrake Supplemental Braking System part # RM-8700, in order to set the brake pressure you must first pull the breakaway pin and then pull out on the knob. Then, rotate to the designed psi, reengage the knob, and reinsert the breakaway pin. I have attached a photo below with these instructions. If the brake pressure still fails to set, there may be a hardware issue and a warranty claim with the manufacturer would be needed.
