How Do Self-Adjusting Brakes Adjust and Does it Work Going Forward or Reverse

Question

Question:

I remember back in the day when cars had self adjusting drum brakes, the driver had to back the vehicle up for the self adjusters to work. Their was no instructions with these brakes, is that the way these brakes self adjust?

Self-adjusting brakes # AKEBRK-7-SA do not require that you travel in reverse for them to adjust. They can adjust themselves going forward or backward.

Keep in mind that even self-adjusting brakes require 1 initial adjustment. You could just install them and they would eventually adjust out but until that happens you would have weak brakes. Basically if the brake shoes have to move too far before they touch the drums a pulley spins the adjustment wheel which then takes and adjusts the shoes out a bit further. This would happen in forward or reverse.

I just installed your AKEBRK-35-SA kits on my travel trailer. In order to get the drum on I backed off the start wheel adjuster the entire way. I just took the trailer for a spin for the shoes to adjust and they have not even after stopping for a dozen times. I hear the magnets energized. Do I just keep breaking because they have a long way to adjust?Thanks

You want to adjust the brakes so that when the trailer tires are off the ground and you spin the wheel, they have a very slight drag to them. You will be able to hear the brake rubbing on the drum. What this does is makes sure the brake pad is as close to drum as possible so that braking response is fast. We have a adjustment spoon # W80630 available that you can use to adjust them properly.

The magnet clips #BP19005 should not be making contact with the drum while the brakes engage, so I do not think that is the problem. What I think is going on is it's just not seating all the way. These can get a little squished or deformed…

Hey Brian, if you grab the magnet and move it in the direction of the arm that it is attached to far enough it will click and it will adjust the star wheel tighter. This will be the easiest way to move the shoes out. Or you can install them and then…

The inner diameters of the LM67048 and 15123 both are the same (1.250 inches). That means that a hub with either bearing in the outer bearing would fit your spindle. The part #AKHD-655-6-EZ-K would fit your axle.
