I always bleed the new master cylinder on the bench before fitting to any
car.
I always fit a duel circuit to all my classic cars, so what I do is bleed
the front outlet 1st.
Now to do this, is clamp the master cyl into the bench vice.
Next, only pour brake fluid into the front part of the master cyl, and
then push in the piston with a blunt screw driver and having your finger
over the brake pipe port.
Keep doing this to the front reservoir till all the air is out.
Now, fill the rear reservoir and do the same, but this time place your
finger over both the brake pipe ports.
And once you feel you have all the air out, should take quite a few
pushes, then bolt the master cylinder to the car, and fit the brake
pipes.
You will still have to bleed the whole brake system, but doing the master
cyl on the bench makes the bleeding process alot quicker.
I hope I have described this well enough to you?
Jim

Subject: Bench bleeding Master Cylinder?
I am working on the brakes on my 63 SF and just switched it to a dual
master cylinder.
I had to install the master cylinder to do the piping but it has never
had fluid in it.
Do I really need to bench bleed the master cylinder? Given a choice I
would not like to remove and reinstall it and I'll be dealing with a
master cylinder that is dripping fluid.
Thanks
