Video Transcript for Dexter Axle Trailer Brakes 23-404 Review

Today we're going to take a look at the Dexter 12 and 1/4 inch by 4 inch Driver Side Forward Self Adjust Hydraulic Brake Assembly with a 10,000 pound capacity. Now this hydraulic drum brake assembly's designed for use with surge type trailer brake actuators. Is it the dual plunger design which will deliver the same amount of braking when driving either forward or in reverse. The size on this is 12 and 1/4 by 4 inch, it's a driver's side hydraulic trailer brake assembly. The size, when we say the size, that's actually the 12 and 1/4 would be measured straight across from the pad to the other end of the pad. You can see 12 and 1/4 inches.

The 4 inches would actually be the width of the pad, so you can see edge to edge right at 4 inches. This is the left hand driver's side and the way you can tell that now on a new assembly you usually have a sticker that'll tell you left hand or right hand. If you didn't have the sticker on there the easiest way to tell is you look at the length of the shoe pad. This one you can see goes from here to here and this one goes all the way from here all the way to here, this is a longer pad. This one's the shorter pad, the shorter pad is your primary shoe so that would go this way and it always faces towards the front of the trailer. That would determine if this is the driver's side brake assembly, that's the easiest way to tell. Now the friction material on the pad is fully bonded, it's not riveted to the shoes, gives you a lot longer life, more braking torque.

Now this is a forward self adjust brake, you can see the cable goes around a pulley to the level here. Basically it will not require any periodic manual adjustment like standard brakes. After you install this you make your initial adjustment and then they will self adjust as you go forward. Now this is designed to fit on the 7 bolt brake mounting flange. If I turn it over you can see 1, 2, 3, 4, 5, 6, 7.

The mounting hardware is not included, that is sold separately on our website. Now this assembly is certified by USSAE standards. Again the dimensions on this is 12 and 1/4 by 4 inches. The weight rating on this assembly is 5,000 pounds so when this one is used with the other assembly on the other side to meet your axle rating of 10,000 pounds. Again it's a left hand driver side and this does use the 12 and 1/4 inch brake drops. That should do it for the review on the Dexter 12 and 1/4 inch by 4 inch Driver Side Forward Self Adjust Hydraulic Brake Assembly with a 10,000 pound weight capacity..

  • 10k Hydraulic Drum Brake Assembly Recommendation
    I looked up your trailer and it looks like it has two Dexter 10k axles. I couldn't find info on the actual brake style though. You hinted that they aren't like electric brakes. Are they disc or hydraulic possibly? Do you have any pictures?

  • Switching My Electric Drum Brakes to Hydraulic Drum Brakes on Dexter 10k Axles
    We carry disc brake kits for the Dexter 10K Standard Duty axle. Unfortunately, there is no disc brake kit available through our venders that fits the Dexter 10K Heavy Duty Axle. You could upgrade to a hydraulic drum brake system from your electric drum brakes. You will need Dexter Left Hand Hydraulic Brake Assembly # 23-404 and the Right Hand Brake Assembly # 23-405. If your drums need to be replaced, you will need Brake Drum Assembly # 9-27-1. You can remove your hubs off your current...

  • Titan Replacement Brake Actuator
    To replace your current Titan actuator you are going to need to purchase the Titan BrakeRite I Plug and Play Electric-Hydraulic Actuator Kit item # T4813102. The replacement actuator is out of stock and the only way to get a replacement is to buy the entire kit. Yours was probably cut and wired which is why it is not a plug and play. To use this actuator with drum brakes you are supposed to use the Drum Brake Reducer for Titan BrakeRite Systems item # T4844100.
