Barndoor Brakes

Here's where I am at.

I've got my '54 in the shop to redo the brake system. So far we have:

- Replaced the rear axle seals.
- Replaced the rear wheel cylinders (19mm) with new Oval beetle front cylinders. Perfect fit. (thanks for the tip Everett and Greg)
- Replaced the master cylinder.
- Rebuilt the front wheel cylinders (22mm) using kits from NAPA. (Thanks for the tip Brendan)
- Put a new bushing in the brake pedal assembly.
- Replaced all the flex lines.
- Drums are fine

Questions:

Does anyone have new 22mm front cylinders?
Does anyone carry the brake shoes? Is relining the only option?

Info. greatly appreciated.

Hi Jeff- As far as I've heard nobody has front cylinders nor shoes. Of course, there is supposedly always the possibility that you'll find the needle in the hay stack but I don't think anyone stocks them, at least that anyone I've spoken with is aware of. I've always heard that you just have to reline the shoes and I've seen some NOS pad and rivet sets on Ebay in the past. I think that Mark Smith may have had some??? Good luck!

As far as I know, "new" front wheel cylinders for Barndoors are not available. The only time I have found any was a few times when I saw NOS ones for sale on the Internet. If yours are totally wasted, you could also get them sleeved, although I don't know who does that.

On the shoes, yeah, Mark Smith used to have some pad and rivet sets (he might still have some?) but Ronnie in Lake Havasu told me he got his relined at a place in SoCal.

Hello again Jeff- I have heard that most larger auto parts stores like Pep Boys and others that offer brake drum turning services usually can send your shoes out to have them relined. There was a place here in Pacific Beach called Foreign Auto Supply that I know was able to do it. They are no longer in this location and now I don't know where they are.

Thanks guys. I will get the shoes relined. There is a shop here that does the work in San Marcos.

As for the cylinders, I found that the 7/8" rebuild kits are the correct metric equivalent (22 mm). As for the rear cylinders (19mm) they can be purchased new from NAPA and some of the other shops. They are expensive at NAPA at almost $80 each. OVW in Escondidop has them for $39 each.

I talked to Wolfsburg West and they told me most guys run 19 mm in the front and rear. What is the thinking on this approach? Seems like you need all the braking you can get with those old brakes and going with smaller cylinders in front would hurt you. Do you guys think it makes a difference 22 or 19?

That sounds dangerous, it would mess up the front to back braking ratio? Who the heck does that? I need to make sure I drive behind them at all times.

The brakes on my '55 don't work very well right now, I'd hate to make them smaller.

I know this is an old thread, but i thought i'd add to it rather than starting another on brakes. What i want to know is where to get front and rear brakes hoses for stock barndoor brakes. Wolfburg West list them but are they the same length as originals. I have 481.5mm for the fronts and 265mm for the rear. Anybody have any info on this?

Thanks Linda, if you could get Doug to confirm that the WW stuff was ok, i can order some. So for the master cylinder are we talking a stock 19mm one? I seem to remember Clara using a 356 one on her truck but i can't find that thread. I know real early busses had a 22mm master cylinder.

Its been about 8 years since I really messed with BD brakes, but on an old 52 (that Troy Wheeler now owns) I could swear that we used oval wheel cylinders for the front and just had new pads put on the shoes. I cant remember why, but for some reason the oval cylinders worked and post 55 bus ones didn't. Am I nuts or does this sound right?

PS-I dont advise this, its just what I remember doing.

I guess so, long time ago. Something was weird about it, maybe the bolt pattern didn't match right???

What rubber pieces would one use to rebulid a set of correct barndoor cylinders, assuming all metal parts are OK? [/i]

Get the 19mm Porsche 356 master cylinder from Stoddard. If you drive your bus it's worth the money. Using the later 19mm is bullshit and it works like hell. Tell Doug to rip that shit out and buy the right stuff.
