Quick Tip: There's really not a whole lot to getting new drum brakes. If you've confirmed that all of the specs listed above line up with what you need for your trailer, you can be pretty sure these will work for you.


High-Quality Brake Pads

Riveted brake pads will always give you a screeching reminder to replace your brake shoes. That's because the rivets will scrape against your drum as the friction material wears down. You won't have that noisy problem with bonded brake pads. You'll also get a little more friction pad contact because there aren't any cutouts for rivets. And more friction means more stopping power.


A close-up shot of a drum brake shows a tapered brake pad.

These pads are also tapered, which should help to prevent any broken, crumbly bits of material from rotating inside the drum as the pads wear over time. Brakes without these tapers are more likely to create a jarring braking experience that could cause the brakes to stutter and lock up.


Self-Adjusting Brakes Don't Require Routine Maintenance

With standard electric brake assemblies, you need to manually adjust them every now and then to make sure you're getting the shortest stopping distance every time you tow.


A trailer drum brake with a red callout shows the location of a tension cable and pulley on a self-adjusting trailer brake.

With self-adjusting brakes, though, you'll always have peak stopping power - simple as that! As the brake pads wear over time, a tensioning cable will automatically keep the pads in alignment so they'll consistently make contact with your drum when you brake. You won't have to do tedious manual adjustments anymore.


Thoroughly Tested for Safety

Dexter invests a lot of resources to ensure that these brakes meet the requirements for certification set by the Canadian Standards Association (CSA). Basically, a CSA certification tells you that these trailer brakes are well built and safe for use on the road.


How to Break In New Brakes

Once you get these brakes installed, you'll need to break them in. First, find a long stretch of road or a big, empty parking lot. Once you're there, set your brake controller to its maximum setting and get moving. Speed up to about 40 mph and brake to slow to about 20 mph. Repeat this 15-30 times. The goal is to get the brake shoes and magnet properly seated into your drum. You'll know you've done that when it feels less jerky (and more consistent) each time you apply the brakes.


Note: The brakes will be very hot after doing this, so after every 10 stops you'll want to wait about 10 minutes to let the brakes cool off before continuing. If you don't, you might cook and crack the pad material.

5 Star rating! Parts fit as they should. Excellent product condition. Shipping was fast, only took two days. Teresa J. was very helpful with confirming the parts I needed for my 1991 Butler 10 ton trailer. The old parts were obsolete, she was fast to find a solution. Thank you again Teresa! I highly recommend etrailer.com From parts, shipping and service, all great! This is my third experience ordering from them and I will continue to due so.....
