brake line at master cylinder early 230sl

[Madmerc]

hi all I have finaly received my new brake servo for the early 230sl at$1700 and a new master cylinder and new brake lines at even more cost any way its worth it . because I purchased this 230sl in bits and pieces I have had to reassemble it with what it had and what I have purchased new I have come the mount the master cylinder on and im not sure which outlets are for which brake lines  there is 2 outlets at the front of the master cylinder and 1 out let on the side which I read up  was a  check valve . can anyone help me with some dirctions as to what lines go wher and what is a check valve and what goes in it.thanks

Brake master cylinder is the correct one.
You should see the two front openings and the left goes to the left front brake, the right goes to the right front brake and the third orifice in the back is for the rear brakes.  One line goes to the rear, just before the rear differential and splits to the rear drums.  Does this help?

hi rob decided to adopt your style of writing much easier w/o caps or punctuation. no 't' in the front one line through the fender the other across the firewall held by little clips then through the fender cheers ct.

Early 230SL's have a small brass fitting similar to the fitting at the back of the car that T's near the booster to feed the left and right front brakes. I believe it sits on top of a small stand.

Benz Dr, true if the Master cylinder has only two outputs.
However MadMerc stated he has three outputs on his mastercylinder.
Hence my reply with three lines, one to each front brake and one for both rears.
MadMerc, there should be three lines total at the mastercylinder area.
Find the left front brake line and put to the left front orifice on the mastercylinder and right line to right front to the right front orifice.
The rear orifice is for the rear brakes.
You will need to bend the lines with a pipe bender.
If you only have two lines, one front and one rear, then you have the incorrect master cylinder.
Keeping with originality you need the correct one, if you want to keep the mastercylinder you have, then you need to split up the front lines to two individual ones.  Purchase two new front lines and replace the rear as these rust inside and peace of mind with new lines.

No, Walter,
I do not agree. Dan (Benz Dr) is correct here, as usual. 

Your observation is correct, the "modern" current brake mastercylinders have three outputs in contrast to two which they had in the old days.
What you do in such cases then is to block one of the two front outputs. I think to remember that the plug is already included with the master cylinder.
Please note ....: do not change the original setup where not absolutely necessary.
 

Best,

I've seen and worked on both versions which is why I mentioned it.

 I must be getting old ( I am ) because I've been proven wrong enough times that I'm not as interested in always being right. Getting something right is probably more important than being that way.

Thanks for the correction Achim.
I stand corrected, and I'll shut up.

And the tell tale as to which master cylinder was fitted when the car was new is the bracket that is welded to the chassis leg with which to mount the brake pipe divider as shown in Achim's picture.
This bracket was deleted when the master cylinder was changed for the three port one.
