Disk Brakes...... WOW

[padredw]

I did not do the installation myself, but I had a problem with the flexible hoses that went from the metal tubing to the drum itself. I think these may be the fittings and threads that you may need to know about:

You can enlarge the image and see the threads and fittings pretty good. I had to drive from Brunswick, GA to East Texas without any trailer brakes because no one had these hoses in stock. I now carry some extras.

If I'm barking up the wrong tree, just forgive and procede.

Then for any DOT flex lines - you will be hard pressed to find any for 3/8" line.

prndl, these rotors are similar in thickness to the '80s and '90s GM rotors which then support the GM style SAE calipers of the same vintage. This is what the 6K look like, 7K are virtually identical but with 8 lug hubs (yes, I did pull my axles and repainted them):

What brand is the disc brakes in the picture?

Good info. Didn't quite answer my question but still useful.

Let me ask this. Was there a fitting that could be screwed out of the housing where the hose makes connection?

Good news from me is there are several hydraulic hose making shops within just a few miles of my house. Specific to your type of hose, you may well find that some of the auto parts houses are able to make the hose. I have a O Rileys that makes hoses. Not for certain they would be able to make that one but would be worth a try. Better than traveling several hundred miles without brakes for sure.....

Even though I did the replacement of the two flexible hoses (which happened to be on the two rear wheels, one on each side), I can not answer this. I just used the existing fittings as the hoses were exact replacements.

As an aside, It was over 800 miles from Brunswick to my home and, though I would never advise anyone to do this, I really had no trouble. My 2500 Duramax/Allison Chevrolet handled the braking quite well (31' fifth-wheel), even in the many small cities we had to go through. I must say I was very actively engaged in driving through the towns.

The problem I had was that the installer made a mistake that allowed these flexible hoses to rub against the tires until a hole allowed all the fluid to leak out. I stopped several times at shops and parts stores but no one had hoses that would fit on my drums and lines.

Just thought I'd give the back story. The installer supplied the replacement flexible hoses and a couple of extras and I installed them myself.

Ok thanks for the reply.


One of the reasons I like the idea of running SST braided flex lines is it significantly reduces the chances of abrasion failures.

I'm going to bow out of this test of wills because we both are beginning to compress a lot of hot air which usually leads to no good. I will however answer a question of yours. The fittings screwed into the Kodiak calipers that accept 3/16" industry standard inverted flare flex lines have 3/8-24 female threads for the nuts and 1/8" pipe thread going in to the caliper. The fitting that screws into a Hydrastar unit "appears" to be 7/16-20 threads although it may be metric. It is straight thread o-ring seal. Why one would go to the trouble of having special flex lines made to go from frame to calipers makes no sense to me when you can go to about any auto parts store and get 18" flex lines already made for the fittings and frame mounting bracket at hand. Besides ... when out in "bum flop Egypt" and you pop a hose ... who's going to make up your special hose? Oh ... OK ... drag along spares to accommodate your whim. I will not say more due to the constraints of this forum. If you want to see a quality installation that won't look like something that belongs on a back hoe

I'm seriously looking at the complete kits from Performance Trailer Breaking.

Anyone have experience using these kits?

"Both me and Dave can lock up all four at 45+ mph on dry asphalt with our 3/16" line " Okay am i the only one picturing
A. The hitch being ripped out of the truck
B. The bed of the truck being ripped off of the truck
C. the MORride Elastamers being stretched out and yanking the truck back.

Yes, I grew up watching BW silent movies and Road Runner cartoons.

I looked at their offerings when doing my research and found them over priced vs the 'kit' I made up

i did it at 65 mph on i-87 near exit 25, not at 45 mph

a. The hitch being ripped out of the truck

nah! Not a b&w on ford pucks

b. The bed of the truck being ripped off of the truck

a ford? No way 109,000 miles+ and still solidly attached

c. The morride elastamers being stretched out and yanking the truck back.

they still work and look good at 22,000 miles even though one was assembled wrong by the mfr.:d

yes, i grew up watching bw silent movies and road runner cartoons.

no mery melodies or tom and jerry cartoons? Heck, saturday movie matinees were my staple and the 25 cent allowance got me in for a double feature as well as a bag of popcorn

Hmmmm shame you didn't show THOSE pictures to begin with. That is actually a very clean looking setup. I may well just go with that.

But if you haven't seen SST braided lines used before you obviously haven't been to a car show and looked under the hood of a custom......

Thanks for the pictures.

Good luck finding DOT approved braided SS lines with SAE male 45 degree fittings!! Lines made up at a hydraulic shop will not be DOT

Every fitting on this chassis is AN and 37 degree - because they had to be. Every SS brake flex line is DOT, the low pressure lines (fuel, trans fluid, vacuum, etc) are all made up by myself

Now that is a clean looking setup!

X2! Very nice!

Does the Ford factory integrated brake controller work well with the Hydrastar controller? I was reading on Etrailer about an issue with the Brakerite EHB.

[prndl]

I've noticed some installations use one flexible line from the frame to each axle and then "T" to service both brakes on that axle.

Others have installed a flexible line from the frame to each wheel.

The first would be the simpler installation. Any reason not to go that route?

Your '14 will but you do need to change the function on the dash info panel to electric over hydraulic

Also, for sure, all '11- current will work with the Hydrastar. There are a few years where you will need either their 'adapter' or a Prodigy 3 or 4. Dig into the Carlisle Hydrastar site and any pick ups prior to '11, can find which years. Some late Dodge/Ram and GM trucks also need the adapter or Prodigy

Actually, both are pretty simple - and I am changing my mind towards the Kodiak flex line system - as long as I don't have to coil up a bunch of loose hose length. There are kits with 15 to 24 foot initial lengths. The solid line is not for every DIYer as it requires a good tubing cutter and a 45 degree double flaring tool

[beeje]

My trailer has the single flex line to a block on each axle. Out of the block, a line goes to each side. Its hard piped to the caliper. Just looking at the set up, I don't think I can install new pads without disconnecting the hard lines. Not sure, have not tried yet and will not have to until the pads wear out.

If I would have installed the system I would defiantly install a flex line to each caliper like any car would have.

I don't understand why they did what they did.
