Replacing brakes on my SIIA LWB Ute

[srowlandson]

I am about to replace all the brake lines / pipes / fittings on my SIIA '64 LWB Tray.

I know the line i need, and that i need 30 Feet of pipe to do the whole car, what size and how many of the fittings do i need. I have a double flange brake pipe tool ready to roll.

Steve,

Can't help with the answer but.....
I'll be doing the same to mine in..........well hopefully not too long. If you feel keen, could you take a few photos, list a few stats/tips/issues and post here or in the tutorials section. An novice like me would really be interested.

G'day All, The bits you need are called tube nuts IIRC, they are 3/8" UNF thread, any good brake parts supplier should have them in stock. You will quite a few if you are going to replace all of them, from memory here goes
Front axle 2 per side = 4.
Rear axle 1 each side (at wheel cyl) then 3 from the interconnecting pipes = 5.
Brake Master cyl =1
3 way junction on chassis top rail = 4>>>>> add em all up = 14 x 3/8"UNF tube nuts.
Then for the front axle you will need a different type again (so take note of what is fitted) the flexible brake hose has a 3/8" UNF ?? acorn style nut internal thread, you will need 3 of these (4 if you intend to do the clutch line as well!!!) they are fitted to the pipes that connect to the flexible lines 2 at the front and 1 at the rear of the vehicle.
Have you got the vehicle stripped down?? as it's a little difficult to do some pipes with the body insitu, anyway nonetheless it can be acheived with some thought and patience, anyway good luck with it cheers Dennis
PS Always remember to fit the nuts before flaring, dont drink whilst doing the job or you will be in a stew LOL.

When you purchase the line, get the pipe that looks like copper but is actually proper steel brake line. It comes coiled up, and is much easier to hand form than the pipe that comes straight. I have just done my SI. This was done in 1/4 tube, with 7/16 fittings. This is different to SII/SIIA.

G'day srowlandson

Here is a few part numbers that may be of help to you, the flexible hose for the rear axle on the standard suspension 2a is
RTC-3353 this is also the clutch flex hose, if the vehicle is Ex-Army with a raised chassis, these RTC-3353 Flexible Hoses are also the ones used for the front lines

THIS HOSE IS ALSO USED FOR PARABOLIC SPRINGS


The following numbers are the Exchange Brake Shoe Part No's, for LWB 4 cylinder vehicles.

Front Exchange. E1420 Std. also available is 1st oversize,O/S= +.030thou

Rear Exhange. E1092 Std. " " " " " " " "


hope this is of some help

cheers

Steve the tube nuts may not need replacing; they usually scrub up well on a power wire brush and can be re-used, unless badly corroded, or if the flats have been damaged,

Geez, if you have to buy any new nuts make sure they're right. I've had some real headaches with this. The British type are what you want, of course. The male nuts have a plain section below the thread, which pushes against the flare. American nuts don't: the thread just goes to the end. Apparently this won't seat the flare properly.

G'day All, A metal turning lathe soon fixes that problem with thread to the ends, a quick spin soon removes that LOL, but in his post he stated he was going to take a sample, I love making brake and clutch pipes cheers Dennis

thanks for all the advice, i'll visit ABS thursday before work, can't go tomorrow as i pick up my new Aurion from Toyota yippee.


I'll go all new for ease, knowing its new makes fitting easier. i'll clean up the old ones for 'spares'

photos and updates coming soon. picked up a double flaring tool (blue point) form the US Ebay last night, hoping it gets here soon enough to try it. car iscurrently chassis + firewall and back of cab - no roof / windows / windscreen fitted, so should be easy to redo the brakes, before the engine goes in and the front axle gets bolted on.
