Question:
Do these kits include the drum? AKFBBRK-7L-D and AKFBBRK-7R-D
asked by: Richard D
Expert Reply:
The Hydraulic Brake - Uni-Servo - Free Backing - Dacromet - 12" Left # AKFBBRK-7L-D and Right # AKFBBRK-7R-D you were looking at do not include the drum. To mount these brakes to your trailer you will also need Mounting Hardware # BRKH12
These brakes require a 12"x2" hub, but to determine the correct hub for your trailer you will need to know which inner and outer bearings your spindles use, and the bolt pattern of your current hubs.
The easiest way to accomplish this is by removing one hub and reading the numbers stamped on the front of the bearings. You can see this in the included video of the # L44649 bearing I included.
If your bearings are worn where you cannot read the number, you will need to use digital calipers like # PTW80157 and measure your spindle in the areas shown on the included diagram.
To find which bolt pattern your current hubs are, I included a helpful article that walks you through how to measure the bolt pattern on your wheels.
If you can provide me the bearing numbers/spindle measurements and which bolt pattern your current hubs are, I would be happy to recommend the correct hub that will work with the # AKFBBRK-7L-D and # AKFBBRK-7R-D brakes.
