Launch your boat without locking up your brakes. Free-backing brakes are a must-have if your surge actuator doesn't have a reverse lockout. 10" x 2-1/4" Marine-grade assemblies fit 14" to 15" wheels. Made in the USA.
Features:
Specs:
If you have a seasonal boat or a snowmobile trailer that's occassionally in lakes or on heavily treated salt roads, these are the brakes for you. The galvanized backing plates. stainless steel springs, and zinc-plated wheel cylinder all provide excellent rust and corrosion resistance so your trailer will be ready to tackle the season.
Pro Tip: If your trailer is near saltwater year-round, you may want to look into the increasing levels of corrosion protection that e-coat, Dacromet, and stainless steel components can provide.
Backing up your trailer might be the only time you don't want the brakes to work. Normally, this would be a job for the reverse lockout on your hydraulic actuator. But if you don't have a lockout, you'll need brakes that will you allow you to back up freely instead.
How do they work, you ask?
During normal forward braking, a fall-away shoe expands to catch your brake drum with enough force to bring your rig to a stop. When driving in reverse, however, the extra springs on these brake assemblies override the brake cylinder. This prevents the shoes from fully catching on the drums, which takes away your braking control, allowing the wheels to continue to turn.
Note: Free backing brakes don't activate when you're in reverse. So, keep in mind that a trailer breakaway kit will not be effective if your trailer were to disconnect from your tow vehicle while you're backing up.
If you often find yourself making hard and frequent stops, these brakes may be for you. The semi-metallic brake pads in these Demco brakes are built to last longer and produce less dust than organic brake pads. They're also bolstered to the brake shoes with rivets, which makes the pads less likely to crumble or warp over the course of their lifetime.
The more miles you put on your trailer, the more your brake pads will wear down. As they lose contact with the drum, stopping distances get longer and longer. To keep your brakes working great, it's important to adjust them pretty routinely. For this job, grab a floor jack and either a brake adjustment tool (sold separately) or just a standard flathead screwdriver.
Jack up your trailer enough to get the wheel(s) off the ground. Remove the adjuster plugs from the backing plate on the brake, and insert the flat end of the tool through the back of the assembly.
Push in on the star gear and lift it up. Keep doing this until the brake pads catch on your brake drum. When you can't spin your wheel by hand anymore, back the gear off by about 10 clicks (push down on the star gear). Does the wheel now spin freely (even if it sounds like the brake pads drag slightly on the drum)? Great! Then you're all done with that one and ready to adjust the rest.
Once you get these assemblies installed, and your lines flushed with fresh fluid, you'll need to break in these brakes. First, find a long stretch of road or a big, empty parking lot. 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 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.

Worked great thks
Advice in purchase was good and delivery was quick. Thanks
Excellent quality and fit.
excellent, high quality
Great fit. My 7000 lb boat has brakes again
High quality parts sold at an excellent price. Highly recommend etrailer.
Great service. Great prices. Timely responses via email and phone. Order was backordered by manufacturer and i was provided the appropriate alternative. Will be using e-trailer in the future.
This is a fantastic deal....makes the brake replacement easy and fast. Great quality. I will buy here again!
Complete kit with the backing plate, 5 bolts and it's together. Easiest brake job I've ever done. Pics of brake kits make sure you have the right kit, and the ordering and shipping is FAST.
Older boat trailer had a wheel cylinder fail and fluid everywhere. These were easy to bolt on and a perfect replacement for what I had. This was not my first order from etrailer and I would recommend to anyone! Extremely fast shipping even when I just chose the regular, free method.
Great product. Easy to install - MUCH easier than changing out individual components such as brake shoes. Don't cheap out by not getting the replacement mounting bolts. If your brake assemblies are bad enough to be replaced, so are the bolts (Ithink they should come with the brake assembly, not separately). This is the second time I have replaced the brake assemblies - no matter how good the galvanizing is, salt water eventually destroys them. Minimal adjustment needed after assembly with the hub.
The hubs are fine but the bearings for one are not, both inner and outer bearing s , inner bearing ID will not match my spindle and and the outer bearing is not fit ing the spindle nor does it fit properly on the hubs, so my trailer is stuck on jacks until I get the right bearings.
I contacted your company to discuss replacing the discontinued brakes on my Trailmaster boat trailer and your Tech person was knowledgeable and accurate with his suggestions. Your website was great, and the videos you have available are perfect. I ordered that day, and I have never had better delivery. The Brake Kits I ordered look fantastic, and they installed very easy with no issues. Excellent product and Great informed people, I'll be back. Thank You. Keep up the great work.
We purchased these parts for a custom build trailer for hauling heavy tool boxes over steep grades. Since completion of the build about a year ago, we have been using it and put a lot of miles on it. The hydraulic surge brake system makes it worry free. We can tow it behind different vehicles of differing weights and wheel bases and not worry about setting trailer braking, it is very nice. We will continue to use etrailer for our trailer needs.
Although I haven't had a chance to put lots of miles on them, all the times I've used them they've performed well. So far no issues.i put these on a dual axle trailer with a 22' boat.

You know when something just works well.... Lol.... This has been my experience so far..... The design along with the function has been very good or without issue. I still havent put lots of use on these... More the occasional use. So nice to be able to back your boat in without issue! You guys have a repeat customer for sure!
This is my first time dealing with eTrailer. There videos, phone help, shipping, ease of tracking, and even packing were second to none. I did price shop and their prices were as low as anyone else. I very highly recommend them.
2000 ez loader trailer complete brake job. 2 axle torsion suspension. All 4 axles . I ordered 4 complete brake /backing plate assemblies and 4 new hubs. My complete order showed up on time afew days later. After I got the trailer and boat jacked up and started to take things apart I overlooked not ordering the transitional flexible brake lines that go from the hard lines into the back of the brake assembly. After traveling for 30 minutes to a hydraulic brake line shop to have lines made up they told me they did not have the fittings I really needed these lines to get this job done for the weekend to get the boat out on the water. So I called etrailer and was connected to Tiffany who I must say provided the best customer service I've ever experienced she worked with me on getting the correct items and set up next day rush shipping. She even personally made sure that my order got out the door and called me personally to let me know . There aren't too many companies that goes to that length to serve their customers. The next day at 10 a.m. the were delivered to my front door. (From half way across the United States ) . I was trilled to say the least. Thank you etrailer and a special thank you to Tiffany. In customer service for your personal attention and follow up regarding my order.
