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 mys=
elf some time back. I seem to recall that this paragraph is not in all of m=
y BMC manuals so the advice within may not be available to all concerned. M=
y car is a '62 so it's fair to assume that the relevant threads are a bit w=
orn...........I use this method along with a Gunson's Eezibleed and it seem=
s to work. I recall that the Eezibleed is much more effective and the proce=
ss 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!
=93If the bleeding of any cylinder continues without success for a consider=
able 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 downwa=
rd stoke* of the pedal and allow the pedal to return fully before re-openin=
g it. Close the bleeder screw finally during the last pedal application.=94=
 (+/- 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 cl=
ips!!
Simon
