Are Lippert ABS Brake Assemblies 10" 3,500lb Self Adjusting On New 5th Wheel?

Question

Question:

I’m trying to figure out if these Lippert brakes are self-adjusting. I don’t want to crawl under the trailer every few months. I'm looking at a new 5th wheel that has these so I'll come to you for parts in the future.

You’re in luck, Dave. Yes, the Electric Trailer Brake Assembly for Lippert ABS Hubs 10" 3,500 lbs # LC73PX are self-adjusting electric brakes. After the initial setup and brake pad break-in procedure, they’ll automatically adjust the brake shoes as they wear, so you’re not stuck with routine manual adjustments.

That means better braking performance over time and one less maintenance chore. Just give them a couple of brake applications after install to help the shoes seat properly.

Then if you ever need replacement ABS brake assemblies or ABS hubs/drums in the future, we got you covered Dave. What kind of new trailer is this? Grand Design? You'll notice a huge difference with the new anti-lock braking system, especially in a panic braking situation.

Andrew, if these Lippert 10" self-adjusting brakes keep themselves dialed in, how do I know when it’s time to check or replace the shoes?

@Dave The self-adjusting feature means you don’t have to crawl under and tweak the star wheel every season, but you’ll still want to do a quick inspection during annual maintenance or when you’re repacking bearings. A good rule of thumb is if the shoe lining is down to about 1/16"–1/8" thick, it’s time to replace. You might also notice longer stopping distances or uneven braking. Do you usually do your own maintenance, or have a shop handle it? Other folks with self-adjusting brakes - how often are you finding replacements are needed on your rigs?
