Can you save a Travco Relationship ??

Unread postby datsit on Thu Sep 22, 2016 12:12 am

How is the brake up grade going with your Travco ?? I'm looking for your experience in doing upgrades / changeover / mods ? What have you done ?? What are you doing ?? WHAT DO YOU KNOW ????????
I had seen some emails (over the years) of people doing some brake work with no follow-ups as to what works ??
AS I have just experienced my last trip in BD as a single brake system sooooooo !! he'll be sitting out back for a while and may determine our future, the last trip could have AND may be our last !!
I can get a complete / everything (remove from vehicle / anything needed) brake systems off a couple of Travco's OR Winnebagos I know of, my choice is a ;
1975 travco 270 m400 Travco 5 bolt 19.5 1 piece wheels, front disc/brake / axle / diff / boosters ETC
To replace the brake / suspension on my Travco;
BD is a 1969 Travco 270 M375 / single/master, 1 Vac/booster, drum brakes, 5 bolt 19.5 wheels.
DID : you replace the entire rear end / can this be a straight over changeover (springs down to diff?) or just diff OR backing plates on existing diff ? Did you replace the front ? straight over or what mods did or are you doing to fit the new dic ? brakes on to your Travco ?? Will the brake pedal & master/cyl mount into same location as old system ?? Has anyone just done a master / cyl upgrade to a duel / system with a junction box / splitter of the master/cyl and / or do I need to go from 1 Vac/booster to 2 ???
What can be done to rescue this 14 year relationship & be safe driving for me and future owners (my kids ??) OR will we be parting ways ???
Thanks You Mike

Mike, I sure hope you get some lengthy detailed information! I am in the throws of a brake upgrade myself. Rosie was on her way to a complete failure of the front brakes. A set of broken points saved the day! In 50 miles the pads wore down to the backing plates and tore up the rotors. I had high hopes that the conversion to disks had been done competently.... Alas I was mistaken!! So now I am working out the proper set up so that the braking system is all that it should be.

72 270 with 5k front axle and 2 pot master so the disk part of the swap is fairly straight forward. Except.... disk side should be hooked to the larger (rear) pot in the master...... it wasnt :(
72 had the 8500lb axle in the rear so smaller brakes. I hope I can make this part work well with the disks otherwise I guess I will be hunting a 10k brake set up or have an awful lot of cool parts for sale

there should be a proportioning valve in the system... there wasn't

so if you have acess to a complete set up in decent shape then it shouldn't be a terrible swap. both axles should fit onto your springs which will give you modern brakes with semi available parts.

I hope to see lots of input on this as good brakes make sense and I sure want to be able to bring 7 tons to a stop!
Best of luck with your hunt for good brakes!! Chip

Yeah, Single system is not good. The parts off the 75 should pretty much bolt on I would think. The only thing I would not be positive about is the rear drums. Might have to use the whole rear diff from the 75.
I have owned and worked on a few of these but never a single system.
I have an old F600 with a Single circuit. Not in love with it but I have used the truck for years with no issues with normal maintenance.
I might be getting in a set of 10 Lug axles from an F-450 super duty if the measure out right.
