Ordered disc brakes today!!

You guys are as bad as the Harley Davidson forums!
I ordered my disc brake kit today and am looking forward to getting started.
It seems like the right thing to do, these big trailers are a handful in a hard stop situation.

Man, that is the one mod I really want to do as it is SO much better than the drums. Post up some pics in you would. Just to make me more jealous!

Let us know how the install goes assuming you are doing it yourself.

I will take some pictures, I'm hoping it's as good an idea as it sounds.
I'm due for a bearing packing anyway so thought I may as well. The brakes on these things are smaller than an old 1/2 ton pickup. Here's to hoping.

Man I am pea green!!! The disc brakes are high on the priority list but not as high as the better tires and cushion hitch......


Might as well do the disc brakes with top of the line bearings and upgraded suspension all at once?

The brake setup comes with the new bearings. We have the 4100 Mor/Ryde and the Mor/Ryde isolater pin box, and G rated tires. I’m very pleased with the ride.

I would love to do the 8k independent suspension upgrade to ours as well, but not sure about the funding for that one...

Disc brakes may be the best mod you will ever make on a towable RV

Take a good look at those new bearings as some suppliers don't give you any improvement over the Chinese junk Keystone/Dexter

Ya, I donít know about that one either. I personally am very pleased with the ride of the 4100 M/R on ours. If I was pulling it every day all day long, or even once a week, might be different.
If the brakes are as big an improvement to stopping as Iíve been reading Iíll be happy.

I have disc brakes on my 3455sa and I can stop the entire rig with just the trailer brakes if needed. The difference is NIGHT AND DAY. I no longer feel the camper pushing the truck. I now feel the camper and truck braking as one.

Thatís great to hear. Iím still trying to get my mind around how the braking is Ďproportionalí to the pickup brakes. I suppose itís built into the actuator sensing inertia? Iím really looking forward to them.
I was disappointed to find out that there arenít any American made bearings anymore. Even Timkens are made in China.🤨

Thanks! I did some checking and found even Timkens are made in China. 😕

Dave,
Do you think Timken are manufactured to a closer tolerance even if they are manufactured overseas?
For the 250 bucks Iíd gladly buy the better ones.

Mark, I'm convinced that Timken as well as National, SKF Fafnir, NTN and Bower just to name a few are a better choice then the unbranded Far Eastern bearing manufacturers products and are made to ISO and ASTM plus other worldwide standards you can actually find on the 'net while the unbranded bearings are at best, questionable since you usually can't find their manufacturing criteria. I have never had a common branded bearing fail. As far as Timken manufacturing bearings outside the US and other folks bone of contention, that company at my last look made bearings in 27 different countries but have to assume built to their worldwide standards.

If you do choose to go with Timken, Rock Auto Parts has usually had better pricing then Amazon even with shipping charges.

Couldn't be more pleased. The stopping distance is remarkably less. Probably the best thing I've done to the trailer so far. Tom at Stopyourtrailer.com was very helpful, I elected to buy new Timken bearings and races and I saved the China ones for Emergency spares.

We had discs installed at the Coos Bay, OR rally in June. Went from the brake controller set at 9 to 4.5 and the rig stops much better than just the truck alone. We opted for the Timkens, and they were only a little less than $40 per wheel, and the outer bearing on the 8K disc hub is larger than on the 7K drum hub, so should be much more durable. This photo is at the end of the first short day of installation, still needing the plumbing and the controller installed.

They used the Dexter K71-908-00 disc brake end kits that are the 7/8k 13Ē rotors with 9/19Ē studs along with the Brakerite by Dexter EHB 1500psi actuator. Also used were the random axle install kit, new lug nuts, the Ford/Chevy controller adapter, and I had the Timken bearings used instead of the ones from Dexter. All this was put together by Performance Trailer Braking and was shipped to the RV park where the rally was held at. Their installer was there for a couple weeks and also put on a couple presentations for the group.
