Banjo fittings on master cylinder

[BPDRacing]

I say a picture of what looked like a 98+ f-body master cylinder that had banjo fittings on it. Looked real nice and would be an improvement over my handformed hardlines.

Anybody know where to get these fittings and how to convert the master cylinder?

Thanks.

You need to know the thread size and pitch on your master and then buy them from here http://www.purechoicemotorsports.com/index.cfm/page/ptype=results/Category_ID=146/home_id=94/mode=cat/cat146.htm

My guess would be the MC has to have a hard pretty flat surface to seal the banjos cooper or aluminum seal/washers on.

yeah, it does have to be flat but the master can be aluminum or iron. You are sealing with an aluminum crush washer. Some polished aftermarket masters require a spot face where the washer would sit in order to seal......learned that one the hard way.

I believe that Wilwood sells some of these for their Masters...

spot face donny?

That's what I call it, that may or may not me correct terminology. Mount the master cylinder in the mill with the ports pointing up and and machine a flat spot where the crush washer would sit. I have only had to do this on the polished masters and it usually only takes about .020" depth to get a flat surface.

Never seen this or even thought of it, but it sounds like an awesome idea.

Aside from the fact that every time you crack the lines you need to replace crush washers, but how often are you gonna be doing that?

Unless you are certain the surfaces have been machined for this purpose I would machine them to ensure a seal.

Also, I cannot think of a good reason to swap hard line for soft. You want as much hard line in the system as possible to reduce system compliance.

Thanks for the info everyone.

If you saw the hardlines I bent up using just my hands you may rethink that opinion LOL. The lines would only end up being about 8" long so I don't think it would be too bad. Besides I don't plan on using stock rubber lines like the ones you find on most cars.

I did this to a clutch m/c - looks much better than the hardlines and 3-4 adapters I had before. -Bob

Yup, no problem on a clutch master. The clutch system relies on system stiffness far less than brakes.

BPD, tube benders are cheap and produce very nice results even for a hack like myself. I know that is not what you want to hear, but there is a reason these are hard lines to begin with.

You can also get 3/16 and 1/4 in tubing bending pliers. I can bend a VERY tight spiral if given time. Cunifer line wold make replacing and making lines to master cylinders much easier, yet there are limited sources. some pieces can be had from older volvos, it is greenish in color and wont rust like regular line.
BUT from master to a splitter block and adj prop valve short braided steel lines make routing in tight, hot engine compartments much easier. since my Monza will have twin turbos down road Ill probably use some braided line from Goodridge, custom made unless I buy the swedging tools to do it myself.
basically it depends on your situation. Also you have use aluminum washers on aluminum maaster cylinders BUT use copper if on cast iron, waring to the unknowing. I had tough time explaining it to a guy whos brakes would NOT seal till I changed washers, then he bitched like the dickens even though his car rode and drove perfect. All because I used left over dead soft copper brake washers.
Good Luck

Cunnifer (aka NiCopp) is available from NAPA in 25 ft rolls - just did my Nova using it.
