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.


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.

After doing my homework on what I needed for my Grand Design 230 RL finding the original equiptment replacement parts was essential. After much time on the internet E Trailer had what I needed. I was taken back by the pricing after my search showed some less expensive replacements of the not OE quality. Upon receipt of my purchase I see why the price. Very high quality. Happy me.



by:

Easy to install and have been good reliable brakes for several trips so far. Although, extremely expensive. At over 3 times the cost of the next size down, seemed excessive, but if that’s the size you need you have no choice.

Great service. Got everything fast and complete. Great product and service.

I ordered 2 sets of 10" 2 1/4 electric shoes / self adjusting for my Jayco eagle. Received them about 5 days after i ordered them. have installed all but 1 on rear axle. They were very easy to install and wire. tested them today while burnishing them going to another park so far they work well. hope to finish the last on soon. I did replace all bearings and seals on each wheel as i was changing them out.
