Dexter electric trailer brakes can be adjusted manually or automatically. The Dexter Nev-R-Adjust electric trailer brakes are self-adjusting and can be adjusted by applying the brakes 20-30 times from an initial speed of 40 mph, slowing the vehicle to 20 mph. This process allows the new brake shoes to seat into the drum surface. However, manual adjustment may be necessary if the brakes are not engaging enough to create ample friction for stopping. To manually adjust the brakes, a tool with a fine edge, such as a flat-head screwdriver, may be required to turn the adjustment wheel. Additionally, proper grounding of the trailer brakes is essential, and a separate ground wire network is recommended.

What You'll Learn
Dexter Nev-R-Adjust electric trailer brakes can be manually adjusted
To manually adjust the brakes, you will need to have the truck and trailer on a smooth and level surface. Slowly accelerate to no more than 20 mph, and then step on the brakes. If the brakes seem like they need to be adjusted, it is recommended to manually adjust them first. This can be done by using a tool with a fine edge, such as a flat-head screwdriver, to access the teeth of the adjustment wheel located under the auto-adjust lever. A brake adjustment tool may be too thick for this task.
Additionally, you can try a few hard braking attempts to adjust the brakes, but only if it will not create a dangerous situation. Without an initial manual adjustment, it could take a few braking attempts to properly adjust the brakes.
It is worth noting that the dual slot feature on the backing plates is for reversibility between the left and right sides of the axle. The star wheel will be found behind one clip, depending on which side you are working on. The adjuster will be in the forward slot on both sides, and using a brake spoon to pull down will expand the adjuster, making the brakes tighter.

Self-adjusting brakes: how to tell if you have them
Dexter Nev-R-Adjust electric trailer brakes can be manually adjusted. However, if you have self-adjusting brakes, you won't need to adjust them yourself. So, how do you know if your brakes are self-adjusting?
Firstly, you can check the wheel itself. Sometimes, the capacity is stamped onto the back of the wheel, or there may be a sticker with this information.
If this information is not available, you may need to remove the hub or drum. If you see an adjuster cable extending across the brake assembly, then your brakes are self-adjusting. Another way to tell is to look in the slots. If the spring is flat and wrapped around the adjuster rod, you have self-adjusting brakes. If the spring is curved and below the adjuster, then you have manual brakes.
If you have self-adjusting brakes, you will still have the adjusting wheel and can adjust them manually if you need to. However, if you see a silver-coloured arm, this is an indicator that your brakes are self-adjusting.
Self-adjusting brakes do not require you to travel in reverse for them to adjust; they can adjust themselves going forward or backward. Even self-adjusting brakes require one initial adjustment.

Adjusting brakes with two slots
Dexter Nev-R-Adjust electric trailer brakes can be adjusted manually. However, it is important to note that these brakes are designed to be self-adjusting. If adjusted properly initially, they should not require further manual adjustments.
To manually adjust the brakes, you will need to identify the adjustment wheel, which will have a few exposed teeth underneath the auto-adjust lever. A tool with a fine edge, such as a flat-head screwdriver, will be needed to turn the adjustment wheel.
The dual slots on the backing plates are designed for reversibility, allowing the same part to be used on either the left or right side of the axle. The star wheel adjuster will be found behind one of the clips, depending on which side you are working on.
To adjust the brakes, tighten the star wheel adjuster until the wheel is completely immobilized. Then, loosen it slightly until there is just a slight drag. This process ensures that the brakes are optimally adjusted without creating excessive heat.
Additionally, it is recommended to perform an initial burn-in procedure after installing replacement brakes. This involves applying the brakes multiple times from a speed of 40 mph down to 20 mph. This process helps the new brake shoes settle into the drum surface, improving braking performance and durability.

Converting to electric over hydraulic disc brakes
To set up electric over hydraulic brakes, you need to wire the tow vehicle for electric brakes and install hydraulic brake lines and brakes on the trailer. The trailer's axle must have a brake mounting flange attached behind the existing hub assembly on each side. If your trailer does not have brake mounting flanges, you can either replace the axle or order a new one with hydraulic disc brakes. When ordering a new axle, ensure you know the axle capacity, wheel diameter, wheel bolt pattern, spindle type, and type of brake assembly.
For a Dexter 7k torsion tandem axle trailer, the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers #HSE7K-T1 is recommended. This kit includes everything needed for the conversion. Alternatively, the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs #K2HR712D can be used with the Bearing Kit #BK3-100.
An electric over hydraulic brake actuator is essential for converting to this braking system. It mounts on the trailer and connects the electric signals from the tow vehicle's brake controller to the trailer's hydraulic brake lines. A brake controller is also required and should be mounted inside the cab to allow convenient adjustment of the brakes' action.

Troubleshooting: when to replace brakes
Electric trailer brakes are simple in their operation. When the brake pedal is stepped on, a 12-volt current is sent to a small electromagnet inside the brake assembly, which then actuates the brake shoes. When the magnet is energised, it grabs the face of the brake drum, and the stopping power can be controlled by increasing or decreasing the voltage to the magnet.
Over time, the epoxy coating on the brake actuating magnets will wear from normal use. The brakes should be replaced when the coating has worn down. You should also check the condition of the grease cap, and replace it if it is not seating squarely over the hub.
Before replacing the brakes, you must first inspect the brake controller, which connects and communicates with the brake drum's magnet. Check the wire conditions, and make sure there is no visible fraying, bumps, tears or scoring. Also, ensure the schematic (the wiring diagram) is still with the brake controller.
Once the brakes have been replaced, test for proper actuation. Drive cautiously until the brakes have had time to break in. If the trailer pulls to one side when the brakes are activated, you may need to adjust the brake shoes.

Frequently asked questions
If you have self-adjusting brakes, you will see a cable that runs from the 9 o'clock to the 1 o'clock position when you pull the brake drum off. If the spring is curved and below the adjuster, you have manual adjusting brakes.
You will need a tool with a fine edge, such as a flat-head screwdriver, to turn the adjustment wheel.
After installation, apply the brakes 20-30 times from an initial speed of 40 mph, slowing the vehicle to 20 mph. Allow ample time for the brakes to cool between applications.
If your brakes are not working, check the plug connection for corrosion. If your trailer has been sitting for a long time, there may be corrosion or rust on the inside of the drum, affecting the magnets' ability to apply clamping power to the brake pads.
