Issue With My BrakeRite Electric Over Hydraulic Trailer Brake Actuator Not Engaging Brakes
Updated 01/19/2026 | Published 12/19/2025
Question:
Hi, have an issue with my BrakeRite Electric Over Hydraulic Trailer Brake Actuator. I can hear the actuator turn on when i press the brakes with the pedal and the internal Ram controller switch. I then pulled the emergency breakaway cord. Again i hear the actuator and the trailer brakes do not engage. I then checked the fluid level, which was very low, maybe none at all. I added brake fluid at least 3.5 small bottles, still the brakes on the trailer do not engage.

Hey Sean,
The most common cause of the BrakeRite # T4813102 not engaging the brakes when powered on is due to loose or incorrect wiring, or a bad or loose ground. I would recommend double checking all the wiring to make sure it is secure, and possibly find a new grounding spot. Also in the settings/display make sure it is set to the EOH mode otherwise it won't engage.
If you are still having that issue after those steps let me know and I will continue to troubleshoot.

If you feel the electric brakes activating but no braking capabilities , then you may have air in the system. I use the Phoenix Brake system and push brake fluid from the the calipers up to the master cylinder reservoir. Start at the furthest brake caliper and push brake fluid forward. Then switch to the next caliper etc. constantly check the reservoir for fluid. Suck excess fluid out of the reservoir with a turkey baster. Do this until all the calipers have been bled forward. Maintain the correct amount of fluid in the reservoir , then try the brakes. I’ve used this brake system on 2 trailers. The brakes work exceptionally well. You’ll notice a very slight delay when you apply the brakes but that’s normal because the brake pump needs to pump up. It’s amazing how fast the pump goes from zero pressure to the amount needed.
