1. Dexter Electric Over Hydraulic Disc Brake Actuator: Best Overall
The Dexter Electric Over Hydraulic Actuator is our top pick for those seeking the best braking performance. In our evaluation, it delivers smooth, proportional braking that mimics hydraulic feel without the complexity of a full hydraulic pump. Owner feedback highlights its consistent performance even with heavy loads, and the corrosion-resistant housing holds up well in marine environments. The adjustable gain allows fine-tuning for different trailer weights.
However, this system is more expensive than pure electric disc brake kits and requires running hydraulic lines and periodic fluid checks. It is not the best choice for a simple DIY upgrade on a small utility trailer; for that, consider a direct electric caliper system. If you prioritize fade-free stopping and have a medium to heavy trailer, this is a solid investment.
- Smooth, proportional braking via electric over hydraulic system
- Integrated brake controller with adjustable gain settings
- Corrosion-resistant powder-coated housing
Pros: Excellent modulation and stopping power; Reliable in wet and salty conditions; Easy to retrofit with existing hydraulic disc calipers

We compared its specs to similar kits and found that it includes everything needed for a direct replacement on standard 3,500 lb axles. Owner reviews consistently praise the easy installation and noticeable improvement over drum brakes. The zinc plating helps prevent rust in saltwater environments.
On the downside, some users reported rotor warping after heavy use on steep grades, and the included pads have a shorter lifespan than aftermarket ceramics. This kit is not ideal for heavy-duty commercial use or trailers over 7,000 lbs per axle. For occasional towing or lighter loads, it provides great value.
- Includes calipers, rotors, pads, and mounting brackets
- Direct bolt-on replacement for most 3,500 lb axles
- Zinc-plated calipers resist corrosion
Pros: Affordable complete kit for DIY install; Good stopping power for medium trailers; All hardware included for straightforward installation
Cons: Rotors may warp under heavy repeated braking; Pads wear faster than premium brands
3. Kodiak Disc Brakes Electric Disc Brake Kit: Premium Build
The Kodiak Disc Brakes kit is our premium recommendation for boat trailers and other high-corrosion environments. Our research shows that the stainless steel calipers and vented rotors provide outstanding durability and braking performance. Owner feedback from coastal users indicates minimal rust even after years of use. The metallic pads offer excellent bite and fade resistance, making this kit suitable for heavy loads and steep ramps.
The main drawback is the cost, which is significantly higher than standard kits. Additionally, the stainless steel construction adds weight, which may affect tongue weight calculations. If you trailer in fresh water only or have a light trailer, you may not need this level of corrosion protection. For serious marine use, it is a top-tier choice.
- Marine-grade stainless steel calipers for maximum corrosion resistance
- High-performance metallic pads for consistent braking
- Vented rotors improve heat dissipation
Pros: Exceptional corrosion resistance for saltwater use; Powerful and fade-resistant braking; Long service life with proper maintenance
Cons: Premium price point; Heavier than aluminum calipers
4. Tie Down Engineering Electric Disc Brake Caliper: Easy Install
The Tie Down Engineering Electric Disc Brake Caliper is designed for easy retrofitting on single-axle trailers. We evaluated its pre-bled design, which eliminates the need for separate actuator and hydraulic line bleeding. Owner reviews highlight the straightforward bolt-on installation and the fact that it comes ready to use out of the box. It is a great option for DIYers who want disc brake performance without complex setup.
However, the integrated pump limits its maximum braking force compared to separate actuator systems, and it is only suitable for single-axle trailers under 3,500 lbs. It is not recommended for tandem axles or heavy loads. For small utility or boat trailers, it offers a convenient upgrade.
- Pre-bled hydraulic system for quick installation
- No separate actuator needed; built-in electric pump
- Compact design fits in tight wheel wells

Frequently Asked Questions
Can I install electric disc brakes on any trailer?
Most trailers with 3,500 lb or 5,200 lb axles can be converted, provided the axle has a standard flange pattern for disc brake calipers. You will also need a brake controller in your tow vehicle and a 7-pin connector. Check your axle manufacturer’s specifications before purchasing.
Are electric disc brakes better than drum brakes?
Yes, for most applications. Disc brakes offer better stopping power, less fade on long descents, and easier maintenance. They also perform better in wet conditions because water is thrown off the rotor. However, they are more expensive and may require a brake controller upgrade.
Do I need a special brake controller for electric disc brakes?
Electric disc brakes require a proportional brake controller that can deliver the correct current. Many modern controllers work fine, but some older time-delayed controllers may cause jerky braking. Check your controller’s compatibility or consider upgrading to a proportional model.
How long do electric disc brake pads last?
Pad life varies based on usage, load, and environment. Typical life ranges from 10,000 to 20,000 miles for moderate use. Frequent towing in hilly areas or with heavy loads will reduce lifespan. Ceramic pads can last longer but may cost more.
Can I use electric disc brakes on a tandem axle trailer?
Yes, but you need to ensure your brake controller can handle the increased current draw. Some systems require a separate actuator for each axle or a larger actuator. Always check the actuator’s maximum amperage rating against your trailer’s total brake amperage.
