bleeding brakes. What worked for me.

[Terry,OH]

I believe the 39-41 Ford master cylinder has 1-1/4" internal thread. The 1102 adapter is listed as 1-3/16 does the 1102 adapter tighten down and not leak or strip threads??

There's a few different techniques I've had to occasionally employ while doing the tried and true two-person bleeding procedure. Rubber mallet use to dislodge bubbles is one of them. The other is how the brake pedal is stroked... having to use a staccato tapping on the pedal...... that's been necessary a couple of times. (My suspicion is that it was latent air hiding out in the system)

Having bled various systems since the 70's, I'm always amazed at using speedbleeders. There's something magical about them. Never a problem.
Don't care for Earl's Solobleed design though. Those are junk.
