Re: Rear brake work on my 270

Yes, mine are also 1 3/8" bore and are the same both upper and lower.
I installed NAPA part # 37279 for both on the drivers side and Wagner part # WC113064 for both on the passenger side. All 4 wheel cylinders looked very similar if not exactly the same as the Bendix units that came out and were made in USA.
I broke several brake lines in the process and had to piece them together from two new 20" lines in order to get the long threaded fittings at both ends.

I drove it today and the brakes work great now! :D My brake "warning" light is gone too! ;)

Thanks. I also ran into that problem with the flare nuts. I make my own brake lines so I had to buy the longer nuts. Also I found it was much easier to get the threads started on the upper wheel cyl before I bolted it in.

Also NAPA can get the hardware kit. It does not include the pins that go from the backing plate to the springs though.

I had to loosen the wheel cylinders to get the brake line threads started too. Other than the inconvenience of having to make special brake lines... The most difficult part for me was actually getting the brake line threads started and the U-bolts being in the way.

Not to brag but I gotta say that my coach stops pretty darn good now.
I was looking at my front disc brakes and noticed that they have huge duel piston calipers. I wonder what was the first year for disc brakes and did they all have these calipers? What I am really getting at is the question of how difficult would a disc brake swap would be for an older Travco owner?

I would be easy as long as you have a donor available. The steering box is the same so worst case you swap the whole front axle.. The master is by itself so mounting a different one should be easy.

Hey did you do shoes or just wheel cyls ?
I wanted to do shoes but NAPA cant get the 15x4 that mine are. I may have to have mine relined.

My 15 x 4" shoes were in good shape so I just ran them. I looked them up on NAPA's website and noticed that they were very expensive but I didn't actually try to buy them. hmmm... Now you have me worried about availability.

I didn't see them. Only 15x3 and 15x6,7. I f you can find them post a link.
Relining isnt expensive. We used o do it all the time with Class 8 Trucks.
Old Mack's we did them ourselves. They had brass screws that held the lining on , not rivets.

Strange... I just went to NAPA website and now can't find them.

I found these on Rockauto.com but I am not 100% if they are correct... but I believe they are...
