DRV recall
NHTSA Campaign Number: 16V949000 Issued Jan 3, 2017
Summary
DRV Suites (DRV) is recalling certain model year 2016-2017 Elite Suites and Mobile Suites fth wheel recreational trailers manufactured January 29, 2016, to November 14, 2016. The brake caliper bolts may loosen, causing a loss of braking capability.
Here is a link to it:

With blue no issue, red that would be another story! The recall calls for RED, I disagree!!!

I always wonder why
Why is it recommended that the brake pins be cleaned and lubed once a year. We drive cars for years and thousands of miles and never touch the brakes. I was told the same thing with our Hitch Hiker with Dexter disc brakes. Didn't touch them for 4 years and 50000 miles with no problems.

Yep, with Loctite Red, IIRC it takes 500 degF plus to break it loose. You can't use a torch with the rubber bushings in the calipers.

It's the pendulum effect! Lets make them use RED then the little buggers won't fall off.

I have no idea what anyone else does or says. The equipment used on these RV's is of the poorest quality. I go overboard on maintenance and it has served me well.

Yesterday I checked an Elite Suites 38RSSA with the 9K MorRyde axles at the request of the owner. 2 bolts missing on the right rear caliper; all the others were in place.
The 9K axles use a MUCH larger and heavier caliper assembly than my 8K axles, and the calipers are mounted at the 12:00 position, so gravity kept the caliper in place even with the missing bolts although I was able to lift it out of its mount by hand.
We pulled, greased and Loctited (blue) the bolts on the other 3 calipers. Some were loose, some were tight, some were Loctited, some were not, and none were greased.
Fortunately, the owner isn't moving for a few weeks, so he's waiting on the missing bolts and sleeves to be shipped from DRV. The 9K bolts don't seem to be the 90 Buick Century bolts used on the 8K calipers - we couldn't match them up at O'Reilly's or NAPA.

The 9K system could have been a winner BUT.....
The fact is they use the exact same pad as the 8K does. I considered going to the 9k when back at MORryde because I have 17,500# axle weight. But was not interested since they checked mine out and determined I was still within their specs.
This person builds nearly all the axles at MORryde. Nice guy! 9K in pic.

Maybe, but....., the discs are larger diameter making for more effective braking. Even a small increase in diameter makes a substantial difference.

Could be but the pads are NOT sized to the rotor and will wear out much faster than they would otherwise. You would "think" when making a product for a heavier application everything would be heavier duty.
The pads originally were designed to stop a 3K car with the front pads doing most of the stopping. The reality is they are way undersized for the load they are trying to stop. Surface area is very important in controlling heat.
Larger wheels allow for a larger rotor and when that happens the caliper is larger and pads are larger. I am referring to the modern pickup for example so that should apply to a RV with 17.5" wheels.
MORryde is top cabin but they fell short on this one.
Anyone know if the Dexter caliper setup for 8K axles has larger pads?

With the larger disc less clamping force is required for the same braking effort but more surface area of the disc is used. Probably about the same pad wear for equal braking effort. You would "think" when making a product for a heavier application everything would be heavier duty. Apparently the engineers wouldn't. A Ram 3500 has very few heavier duty parts than a 2500.
The pads originally were designed to stop a 3K car with the front pads doing most of the stopping. Maybe true but, here we have four brake assemblies all doing equal stopping. The reality is they are way undersized for the load they are trying to stop. Can you show any documentation? Or is this just your opinion stated as fact? Surface area is very important in controlling heat. Heat is directly related (although maybe not proportional) to braking effort. More heat would only be generated if heavier stopping was required.
Larger wheels allow for a larger rotor and when that happens the caliper is larger and pads are larger. I am referring to the modern pickup for example so that should apply to a RV with 17.5" wheels. If you say so.

I don't have FACTS nor do you. Common sense is all "I" need.
I should have been more clear. Pickup trucks for example with 16" wheels were limited in rotor size. 17" wheels came along and the rotors, calipers and pads were all increased to provide more stopping power.
They use the same pad on the 7,8 and 9K systems. Maybe 7K was overkill and the 9k is just right.

anijet,
What does the term 'swept area' mean in relation to disc brakes? I have heard that used as one of the measurements used to determine brake size/effectiveness?

Swept area is the disc or drum surface area that the linings come in contact with during one full revolution. Remember the disc has two sides and the drum only has one surface. The larger the swept area the better the heat dissipation. A disc of comparative size to a drum doesn't have twice the swept area but it is something like 160% more.

Got the rig out of storage to get ready for the summer on the road. Because of all the discussion about the brake bolts I thought I should check and lube them. First 3 wheels the bolts were tight as a drum, but the last one was just past finger tight. Don't mean to preach, but check them bolts!

I have been "preaching" caliper maintenance since our first DRV in 2011.
