[Healeys] 100 brakes

[Hank Leach]

Peter-yea, what I think happens there, providing there are no leaks
anywhere else, is that under pressure, overnight, the system "pushes"
the air bubble to the only place that it can get out-the vent hole in
the canister!
I have used this method also for "final bleeding"...could be a line
item on an invoice to look official and garner more dough, Ha. Hank

	Michael assuming you have some resistance after pumping the pedal,
jam the pedal down hard and leave it at least overnight, preferably
longer. Do this repeatedly & you will find the pedal comes up. Don’t
ask me why, but I’ve done this several times with my own and other
people’s cars, and it works!

 Cheers

	We are having a very difficult time adjusting & bleeding the brakes
on a friend's BN1.  

	The car has recently under a full ground up restoration so things
like brake lines including flex lines are new, seals in the brake
cylinders are new, the master cyl. is new, etc.   

	We bleed the system so many times different way that I have lost
track.    

	We have adjusted the free play to assure that the plunger is able to
return to the full "off" position.   

	When we adjust the operating rod to achieve the specified 1/8" free
movement at the pedal.   

	We have adjusted the brake shoes to have a very slight drag at rest. 
 

	Our issue is:   

	Excessive brake pedal travel before the brakes begin to be effective.
   

	Pumping the brakes temporarily improve the pedal travel issue, which
we think indicates air still in the system.   

	We are not having any leaks & the reservoir port is functioning
correctly, IE: no locking up of the brakes.
