  • Options to Fix or Update Brake System on a Tandem Axle Boat Trailer
    First we will need to determine what type of brakes you currently have. I am going to assume that you have hydraulic brakes since this is a boat trailer. If the braking system has not been maintained, along with the brakes, you will want to replace the brake lines and surge brake coupler. Do you plan on using disc or drum brakes and do you plan to have brakes on both axles? My personal recommendation would be to do a complete overhaul with one of our hydraulic disc brake kits. These...

  • Bolt Pattern of Mounting Flange of Dexter 9,000 lb Hydraulic Brake Assemblies
    The bolt pattern of the Dexter Hydraulic Drum Brake Assembly # 23-402-403 that you referenced is is 4.92 inch by 4.92 inch and the diameter of the bolt holes are .545 of an inch.

  • Can 7K 12 Inch Electric Brakes be Used for 8K Trailer Axles
    The Dexter Electric Trailer Brake Kit # 23-180-181 will work for your 8K axles if indeed your current brakes are electric, have a 12" diameter, and measure 2" wide. Standard 8K brakes like part # 23-402-403 though are hydraulic, have a 12-1/4" diameter, and measure 3-3/8" wide. As long as your specs match the 7K electric brakes you're good to go.

  • Replacement Dual Servo Hydraulic Drum Brakes For Dexter 8,000LB Axle With & Without Parking Brakes
    It sounds like you have the Dexter Hydraulic Drum Brake Kit # 23-402-403 on your Dexter P15 8,000lb axle. The Arm on the Dexter Hydraulic Drum Brake Left # K23-171-00 and Right # K23-172-00 is for a parking brake feature. While you will be able to fit both to the same axle I do not recommend using them if they are not attached to any parking brake line. Over time the parts could lead a premature failure since they will not be regularly used. We do have the Kit # 23-402-403 available separately...

  • How Do You Replace The Shoes On The Dexter Hydraulic Brake 23-402?
    It is kind of hard to explain, but it actually isn't as difficult as you would think as well. I included a quick diagram showing what you will need to do as we currently do not have an install video available. The # BP04-260 will replace the shoes on the Dexter Hydraulic Drum Brake Assembly - Duo Servo - 12-1/4" - Left Hand - 8,000 lbs # 23-402, so that is in the diagram as well. There will be a little more to it than what I have shown, but it is mostly just detaching and then reattaching...

  • What is the Right Drum Brake Assembly that Goes with the Left Assembly # K23-171-00?
    The correct corresponding right hand assembly for the Dexter Hydraulic Drum Brake Kit # K23-171-00 is the # K23-172-00. We also sell both of these parts together with the # 23-402-403.

  • Replacement 12-1/4 x 3-3/8-Inch Hydraulic Brakes for 1999 Fleetwood Southwind
    Yes, you can use the right- and left-hand hydraulic drum brake assemblies # 23-403 and # 23-402 on your 1999 Southwind. These brakes use the same 4-bolt mounting pattern as your brake flanges and they are rated for 8K axles so the are a direct replacement. For brake shoes you can use parts # BP04-260 and # BP04-270. I confirmed this with my technical contact at Redneck Trailer.

  • Is Dexter 8-285-11UC3 Brake Drum Compatible with Hydraulic Trailer Brakes
    The Dexter # 8-285-11UC3 brake drums are indeed compatible with either electric or hydraulic brake assembles. Your existing drums would work perfectly with the # 23-402-403 Dexter Hydraulic Drum Brake Kit. I would recommend that you inspect the inside diameter of the drums to make sure they are smooth and in good shape.

  • Looking For Drum Brakes That Fit An 8,000 Pound Axle
    To get the correct replacement brake drums for your 8,000 pound axles, you will need a few things to be verified. The first will be if they are are hydraulic or electric brakes. If they are hydraulic, we currently have the Dexter Hydraulic Drum Brake Kit - Duo Servo - 12-1/4" - Left and Right Hand Assemblies - 8K # 23-402-403 that will measure 12-1/4 x 3-3/8 inches. This will also use a 4 bolt pattern to attach to your axle. If you have electric brakes though, you will need a few more...

  • Recommended Hub And Drum For A 8,000 Pound Axle
    When getting replacement hubs for a 8,000 pound axle I recommend The Dexter Trailer Hub and Drum Assembly for 8,000-lb E-Z Lube Axles - 12-1/4 inch - 8 on 6-1/2 # 8-285-11UC3. The # 8-285-11UC3 has a bolt pattern of 8 on 6-1/2 inches and has a wheel stud diameter of 9/16 inches. It works with 12-1/4 inch brake assemblies like The Dexter Hydraulic Drum Brake Assembly - Duo Servo - 12-1/4" - Left Hand - 8,000 lbs # 23-402.
