[Healeys] 100 (BN1) brake bleeding technique

[warthodson at aol.com]

There would have to be a path (leak(s)) for the "micro bubbles" to escape the hydraulic system. Bubbles will not migrate down, only up. Seems like the micro bubbles would end up trapped at the nearest high points in the system.
Or the system has a lot of leaks at the high points.Gary H

The weird thing for me is when I let the car sit for a month, it sorted itself out.

Gary -
The method that seems to work the best, after bleeding out the system the best you can, is to shove a 2 x 4 between the seat frame and brake pedal, pushing it down with some pressure, then leaving it like that overnight.
Cheers,

Alan

Some have suggested opening the bleed screw, pushing the pedal down slowly, closing the bleed screw & letting the pedal return. Others suggest a similar approach except a very rapid pedal push down, almost violent, like an emergency stop. Does either help to dislodge stubborn bubbles trapped in the 100 brake system?Gary Hodson_______________________________________________
