Tell us what you need
Before you order brakes
A few things to check so the part fits the first time, or just tell us what you’ve got and the parts team will spec it with you.
- Match the brake size
- Electric brakes are sized by diameter and width (e.g. 10″×2-1/4″, 12″×2″). Match your axle’s rating.
- Electric, hydraulic, or disc
- The actuator and controller differ completely between them. Tell us which system your trailer runs.
- Brakes are handed
- Assemblies are left/right specific. Order in pairs or specify the side.
- Controller by axle count
- A brake controller lives in the tow vehicle; give us your axle count so we match the amperage.

Brakes & Accessories FAQ
- What's the difference between electric and hydraulic surge brakes?
- Electric brakes are applied by a controller in the tow vehicle, which sends power to magnets in each brake assembly — you can adjust how hard they grab and apply them manually. Surge (hydraulic) brakes are self-contained: a master cylinder in the coupler senses the trailer pushing against the truck when you slow down and applies the brakes proportionally, with no in-cab controller needed. Replacement parts are completely different between the two systems.
- What size brake assemblies does my trailer need?
- Brake size follows axle capacity: 10" x 2 1/4" assemblies are standard on 3,500 lb axles, and 12" x 2" on 5,200–7,000 lb axles. Measure the inside diameter of your drum, note the axle rating, and check whether the assembly is left- or right-hand — they're side-specific.
- Do I need a brake controller in my truck?
- For electric trailer brakes, yes — without a controller the brakes never engage. Surge brakes need no controller. Most states require working trailer brakes above a certain trailer weight and a breakaway system on braked trailers, so check the requirements where you tow.
