[Healeys] Bleeding brakes.

[simon.lachlan at alexarevel.plus.com]

I am in the process of putting a rebuilt and hopefully cured wheel cylinder back onto my BT7. God, that's an awful job. Anyhow, I shall have to bleed the system when I've finally got those dear little clips to line up.
Recalling past battles in that area, I dug up a note which I'd made for myself some time back. I seem to recall that this paragraph is not in all of my BMC manuals so the advice within may not be available to all concerned. My car is a '62 so it's fair to assume that the relevant threads are a bit worn...........I use this method along with a Gunson's Eezibleed and it seems to work. I recall that the Eezibleed is much more effective and the process much more manageable if one has the donor tyre inflated to considerably less psi than advised in the destructions.
Apologies to all who recall my posting this previously!
“If the bleeding of any cylinder continues without success for a considerable time, it is possible that air is being drawn in past the bleeder screw threads. In such cases tighten the bleeder screw at the end of each downward stoke* of the pedal and allow the pedal to return fully before re-opening it. Close the bleeder screw finally during the last pedal application.” (+/- 2014)
*ie to prevent air being drawn in during the upward passage of the pedal. (SDL 14/08/2019)

Have fun. It's a beastly job but not as bad a s frigging around with the clips!!
