[Spridgets] Brake Bleed

[Weslake1330]

Air can get trapped in a solid brake line and not easily find its way to
the slave to be bled out.  I have heard some people say that after driving
the car a few times the air moves about and then the system bleeds better.
On my Sprite I've sometimes left it a week and then come back to it and
re-bled it with a better result.  I'm also always resigned to using massive
amount of fluid and pumping it all through.  I do have s/s easy bleed
nipples but still use a basic bleeding tool as well.

If the pedal pumps up hard and absolutely stays hard there is still air in
the system.  If it pumps up hard but won't stay absolutely hard - something
isn't quite seating correcting or you have some other sort of leak.

Regards


Daniel
