Installing Kodiak Disc Brakes

As I am going to replace my axles on my 1976 31' A/S I am giving serious consideration to installing the Kodiak disc bake system at the same time. I don't see any problems with me being able to replace the axle, from all of the various posts on the forum seems fairly straight forward. But what about installing the Kodiak disc brakes. Again seem to be fairly straight forward with detailed instructions provided. I am mechanically inclined and have done most of the repair and modifications on the A/S. Input from those that have completed this project would be appreciated.

Thanks in advance

Don

Disc Brakes

There are a lot of brake lines too run, but if you are good with a tubing bender and flare tool, go for it.

Go for it

I too installed new axles and disc brakes on our '88 32'er two years ago and the installation was straight forward. I was able to use standard length tubing so I did not have to flare any ends, just used the bending tool. Lots of folks here will help with any questions you may have. Good luck and keep us posted on progress.

Installed axles and 12" discs on a 1988 Excella 25' a few months ago. Because of cold weather and and other activities, I have not taken it on a trip. A short test drive proved that it stops very well.

A short talk with Andy R. and his people provided axles that fit up very well. The hydraulic brake lines took a little coaxing. The best tools were tube cutter, tube bender and a flaring tool.

Am planning to include pictures and words on my adventure. I'll try to detail my accomplishments and wish-i'd-done differentlys.

The new axles raised the rig just enough to make it ride level. It took a few bumps I encountered very well.

Where to mount the Actuator

For those with Disc brakes, where do you mount the actuator? The setup below from "TinDiesel" in the A frame looks good. Was this a custom made box to hold the Actuator?

Thanks

The best place to install the Actuator, is in an access compartment or under the front lounge.

That, first of all, keeps it out of the weather,

Secondly, you may have a neighbor who also wants disc brakes. Seeing your actuator, might be a tempting source of supply.

I am going to revisit my earlier question on where to mount the actuator in my 1976 31' Sovereign, center bath. The Actibrake manual says to mount in the front of the trailer to reduce the effect of voltage drop through long spans of wire. I replaced my old couch with 2 recliners a long time ago that are mounted to the floor. In between the recliners I built a small cabinet that is large enough to hold the actuator but would be a little tight in getting to it for service. The other option I was thinking about was in the center driver side closet, mounting it on the wheel well. I can snake the necessary wires from the front of the trailer down the driver side behind the fridg and cabinets to the closet. But that would be a total wire run of about 15 to 18 feet. Would that cause a problem.

Also my 12 volt knowledge is not that great so bare with me. In looking at the wiring schematic ( I have attached a pdf image) it all looks pretty straight forward. But a few questions.

1. AUXILIARY HOT WIRE. I assume that the center pin in my 7 way plug is hot.

2. Brown wire from actuator to (+) on battery.Where are to what would this wire actually connect?

3 Breakaway Switch. I will be installing a new breakaway switch that came with the actuator. I assume that I simply connect one wire to the hot wire running to the old break away switch that will be the "Hot Side" and then connect the other wire to the orange wire back to the actuator which will be the "Cold Side".

Thanks

Don

The center pin should be for the backup lights. The real hot wire is the one next to the locating lug on the connector, usually on top.

Longer wire runs require larger wire gauge. Just step up to a larger gauge wire and I believe you will be OK with voltage drop.

What gauge you ask????? The answer would be depends on how much current would be flowing.

Question 12 volt power to the actuator

Does the actuator receive power from the tow vehicle 12 volts through the 7 pin connection, or from the trailer battery while towing?

It gets its power from the battery, which is replenished from the 7 pin connector.

I'm posting this because I'm not comfortable with the reliability of the Kodiak system... read on for my experience. Perhaps others can/will comment on possible solutions.

I had Kodiak disk brakes installed on my 2005 25' Safari in mid-2007. They worked great for about a year, then failed when we were on the road in Montana. I found a dealer who contacted Kodiak - the actuator was replaced under warranty with a new unit. The new unit (different actuator than original) operated much quieter, and the brakes worked great during the remainder of our trip into Canada, then back home to AZ. HOWEVER, a few days ago, while moving the trailer around the house, I found the brakes were no longer working. I don't know the reason, and will be taking the trailer to the dealer who initially installed the brakes to troubleshoot the system.
