If your Coupes brakes are working fine, I would not bother to open up
anything else than the floorboard behind your break pedal.
I assume that the rubber hose that goes from the fluid reservoir to the
master cylinder is brittle and looses the fluid. You need to check there for
a leak
This is not uncommon since these hoses are never exchanged . It is also not
a tragedy to find that hose leaking since the master cylinder has another
reservoir integrated . So the chance that you have air in the break system
is not all to great, unless, you start bleeding the thing without proper
tools.
Don't fix it when it's not broken applies here.
While normal brake fluid in cars should be changed every few years, this
does not apply to the coupe's system. Here we are using aircraft hydraulic
oil that is not hydroscopic as the car's brake fluid is.
(Brake fluid takes water in solution over time. This water is corroding the
system and boils when heated as the breaks are being used. The steam that is
produced while boiling acts like air in the system = less braking action)

Subject: [COUPERS-TECH] Bleeding Brakes
----[Please read http://ercoupers.com/disclaimer.htm before following any

In doing a little routine maintenance, I discovered that the brake
reservoir was empty or nearly so. I then filled the reservoir and
reinstalled the fitting closing off the reservoir.
Now, I suspect that there is air in the brake lines and plan to bleed
that air. Question is: How? My Coupe is S./N 1143 built in 1946. But the
brakes are hydraulic disc brakes. On the bottom of each brake fitting
there is a small fitting with a DeZurk fitting. Plan is to connect an oil
can pump to that fitting and open up the reservoir so the air will have
some place to escape.
The master cylinder is apparently hidden behind floor boards, I am
guessing that the system vent is on top of the master cylinder. Does
anyone know if that is right. I hate the idea of removing that floor
board.
Of course, it is possible that the seal on the master cylinder has gone
bad but I am hoping that is not the case.
Any suggestions or relevant experience to share with me?
