Question:

I have a 2015 Airstream 30ft with 6K Dexter Axles with 42MM Never lube bearing and 12x2 Electric breaks on 6x5.5 wheels. Time for new hubs and breaks. I am wondering while I am at it to upgrade to disc breaks. Can you help me out if this is possible and if so what parts do I need? Also include the new hubs and electric breaks to just replace what I have. Thanks

Hey John. To replace the hubs and brakes on your 6K Dexter Axles with 42MM Never lube bearings, you'll need the following parts:

Trailer Hub & Drum Assembly item # 8-388-80UC3 - These are sold individually and have a 6 on 5-1/2 lug nut pattern.

Dexter Nev-R-Adjust Electric Trailer Brakes item # 23-458-459 - These are sold as a pair and are designed for 12" hubs.

Unfortunately, we do not carry the Dexter disc brake assemblies that fit the 42MM Nev-R-Lube 6K Dexter Axles so I can not help you with those.

Are your brakes the original ones that came on your Airstream? Feel free to answer this and throw in any other questions you have, where it says Add Comment.

Yes they are the original about 75k miles so it’s time for the replacement. These are all the parts I will need?

@JohnS They've definitely lived a long life. Yes, the Trailer Hub & Drum Assembly item # 8-388-80UC3 and the Dexter Nev-R-Adjust Electric Trailer Brakes item # 23-458-459 are all you'll need.

Is there a Dexter Heavy Duty 7k break that will still fit up on my set up? 12x2, 6 on 5,5? We run our break controller in of 2015 F150 at the max of 10 I would prefer more breaking.

@JohnS Unfortunately, we do not have a disc brake setup that will fit your 6K Dexter Axle's 42MM Nev-R-Lube. You're going to notice a massive difference in braking when you replace your electric brakes. There can't be much of your brake shoes left after 75,000 miles on the original set. You should definitely be able to turn the gain down on your brake controller once you get the new ones installed.
