I have a 1978 Eleganza II.
About 3 years ago I replaced the master cylinder with one purchased from Applied. Now I appear to be losing fluid in the front reservoir (which I *thought* was the rear brakes).
Looking at some of the previous threads (and the GMCMI parts interchange book) it appears the 1978 MC was "different".
But Applied only shows one MC listed for 73-78 on their website.
Some of the previous threads here indicate that the 78 had the ports switched from previous years.
I am trying to determine if I may have my front/rear swapped. (and maybe my front reservoir is really my front brakes). Can I trace lines somehow to figure this out?

open up a brake bleeder. give the brakes a couple pumps and then look at the master cylinder. Should show you exactly what reservoir is feeding the brake you are bleeding. no need to trace out lines that way.
front brakes are usually pretty rare to have leak problems, and you will usually see the fluid easily. the rear wheel cylinders will leak and you will never know it unless you take the drums off. So I am guessing you probably have a rear brake leak, that would be the front reservoir on the master.

The Master cylinder should last longer than that.
Call Nick or Gary at our shop and have them send a replacement N/C and
freight free to you.
Should you not be able to wait, we will credit you the for what you paid.
All the ones are made in RedChina and lack quality.Since I look like one,
It makes me blush.
Those that know me well, know I don't blush easily.
