ChiefRocka Split Break Question

[Sharps40]

Chief,

I have a date or three with Ol John Lee (64 C10 SBSS) over the Christmas Holiday.

On tap is:

1. Full front suspension rebuild.

2. Dual Drum/Drum Manual brake conversion

3. Intake manifold gasket/oil leaks

One question. On your Dual Break Master Cylinder conversion thread, you plugged one outlet on the passenger side front tee fitting.

Was the plug you used a special plug with inverted fitting shape to the face or a simple brass pipe plug?

I found my plug at napa. Nothing special about it.

I used an inverted flare plug, easily available as SB70 mentioned.

An 1/8 pipe plug might work as well ....

Thanks. I'll see if NAPA has the inverted flare plugs. Regular parts houses don't seem to either have them or know what they are....

I gotta recheck my lines. I know I have 1/4 up front for the front cylinders and there is 3/16 from either side of the rear T to the rear cylinders.

If the center line from the passenger front t to the passenger side rear t is also 1/4 line, I think I'll just eliminate the passenger front t all together - dispensing with the plug and all the extra places for leaks to start at that corner.

I did this a few weeks ago on my 63, and NAPA had the correct flare type plug in stock.

Cool. I checked the thread sizes on the front and rear flexible hoses. It confirms the front lines are 7/16x24 to connect up to the original 1/4" front hard lines.

The rear hose is 3/8x24 which means both rear hard lines to the wheel cylinders are 3/16" size as well as the line between the right front Tee and the rear hose.

So, I suspect I'll simply eliminate the entire right front tee and run 1/4" line all the way to the back. I can simply reduce at that fitting to hook up to the smaller rear brake hose fittings. It'll give me fewer joints over all and a bit more flexibility in running the lines to the rear.

[Sharps40]

Now I just gotta crawl under to measure all the lengths and get a count on fittings, clamps, etc. And root around in the tool box for the disk that goes on my tubeing bender sized for 1/4 and 3/16 lines. That rooting around could be the longest part of this job!

Chief, I tried a 1/8 pipe plug on my '66--it tried to start for a couple of threads but wouldn't "fit"--but I did not force it in an attempt to "make" it work anyway! Had to use a hard-to-find (at Advance A/p) plug that did fit. We happened upon ONE on their shelf, out of any package, with no way to determine its part#, that fit perfectly. Substantially diff. from 1/8 pipe plug.
