Eh Greg- Don't worry, Doug has two things he's been talking about doing. First is talk of installing a late model dual reservoir master cylinder and the other is talk of lowering the Bus and installing either 356 brakes all the way around or possibly discs.

Is that before or after he chops the nose off his '60 23 and welds it to the back of his '55 23?

Don't worry, whatever he does you can rest assured it will be well executed and tasteful.

Greg, what is the difference between the two master cylinders?

Simon,

When I rebuilt the brakes on my bus, I used later split flexi's, front and back. The lengths are fine.

I picked up a set of front NOS shoes and have re-used the old shoes on the rear as these had plenty of meat on them.

I also have 19mm cylinders on back and front.. as I had no choice, my 22's were shot! and not rebuildable, no many out there either. and I wanted my bus on the road.. so i gave it a try.. Yeah I know its not the most recommended setup to go for but its actually ok.

I have a 17mm bug master cylinder on aswell. With this combination, it actually brakes well... my plans are to fit a set of 22's on the front and obtain a correct master cylinder. However I had discovered that most master cylinders will fit.. I have a later 20mm one that could fit too!

But have heard the larger diameter the master cylinder, the more pressure required to stop.. hence my 17mm is working ok I guess.

Hi Dean,

I think thats how it works, the smaller the master cylinder the more pressure for the same foot pressure it produces. You also have a greater force or pressure from larger wheel cylinders, so a drop in the front Wcyl diameter may be some what cancelled out by running a 17mm master cyl. The only problem is that the front does a big % of the actual braking so should be bigger wheel cyl than the rears.

Mine are stock Bd setup,22 and 19 with a later bus 19mm single master cyl. The van stops ok but even with it mostly being new or nos and after it all bedded in they lack the feel of being able to produce enough pressure using my leg to actually get it to lock, like the master cylinder just doesnt produce enough pressure so i may try a 17mm beetle master cyl and i suspect (hope) that may give a better feeling and better stopping.

Cheers

Mark

That was a type-o, the 356 master cylinder is 22mm. You can get them through Stoddard online, or order them through your local dealer. I've driven barndoors with 19mm master cylinders and the brakes are aweful.

Get new stainless steel sleeves pressed into them....there are a wide variety of sources who do this or you could probably hire a local machineshop to handle it.

I measured the lengths of the hoses that I used on mine:-
Fronts 485mm (slightly longer than regular 55>)
Rears 275mm

I have to say I am surprised so many people are using 2 bolt 'Oval' rear cylinders. We have the correct ones on the shelf at KK!

What is the approx. cost, who are they made by and where are they made? I wouldn't mind having some spares on hand.

Greg, i've read the parts list and workshop manual and both indicate that 22.20mm master cylinders were only used up to chassis number 20-05208. 19.05mm after that. I know you have experience of driving with both so what was the difference when you fitted the 22mm MC? Any idea's why they changed to 19mm?
Thanks everyone else for the info.
Simon

Do all barndoors use four bolt wheel cylinders or did they also use two bolt ones later on?

Mon Jul 09, 2007 6:00 pm

They switched to 2-bolt sometime in 1954.

My April '54 is 4-bolt but my Feb. 55 was 2-bolt.

the shoe on the left came in a box/set of 4 brake shoes labeled bus 53-54 bus rear. any opinions?

Hey Gibbs, the shoe on the right looks like a regular 3/4 ton rear shoe. Are these out of the pest control panel? It's possible that the reduction box was rebuilt to accept the later stub axles, brakes, and drums. Post some more pics of the rear end.

Hey Simon, I keep getting mixed up. The early bd's use 22mm, late bd's use 19mm, and post-bds use 22mm. The replacement 356 cylinders are 19mm.

I'm not sure why busses up to 20-05208 used the 22mm master cylinder like the post-barndoor busses. Maybe the metal brake pipes themselves were larger?

Tue Jul 10, 2007 1:21 am

Gibbs here's pics of the shoes from my bus, i believe they are the same front and back, but different holes are used for the different springs. They are 40mm wide

My rear backing plates have only two bolt holes for the cylinders (feb 55)

Tue Jul 10, 2007 1:38 am

Shoes are the same front and back.. as you say you just use different holes for springs and handbrake levers...

My feb 54 panel had 4 bolt cylinder backing plates front and back,

Tue Jul 10, 2007 6:08 am

cool, thanks. i hadn't looked at them in a couple years. yes eh-greg, the shoe on the right is 3/4 tonner, the shoe on the left is what i was inquiring about. i hadn't been thru the brakes on the pest control panel but that is the bus i bought them for. the seller said they were
"barndoor", they looked a bit different and the price was right.

Thu Jul 12, 2007 1:31 pm

Here's my front shoes. They look good but were recked, luckily my old nextdoor neighbour's Dad had a company which re shoe'd old brakes :D

Thu Jul 12, 2007 2:28 pm

I put Nos liners on mine, then smoked one on the way to Camberg. Outch

Rich, do you know if he had the right ones in stock or did they use some thing vw that fitted?

Incidently i used those 4 bolt rear cylinders KK do on mine, perfect fit and so far no problems, seemed very good quality.

Mark he didnt use either option as the asbestos rating on OG is too high and not as effective in stopping, it's a new modern compound, they are cut and fitted to size and glued to the original metal shoes :shock:

Which body part did you have to sell :lol:
