[Shotimes] Brake Bleeding

[Steve Tatro]

Here's the not-so-humble opinion of somebody on the SHO Forum.  FWIW

"Since the advent of duel safety master cylinders, back in the 60s, the
bleeding sequence has changed. The early system simply divided the
brakes into front and rear. 

More correctly, the bleeding sequence changed when the brakes were
divided into one front and one opposit rear with each end (front and
rear) of the divided master cylinder.

The old standby bleeding method, that is bleeding the fartherest brake
cylinder from the master cylinder first, and then working up to the
closest, is obsolete.

The safest bleeding proceedure for these "new" cars is to follow the OEM
prescribed sequence.

This post is for some of the younger folks who do not know that cars did
not always have a computer and CD player in them. And PLEASE, I say this
in jest, so don't anybody get POd."

Personally, I feel that a bleeding sequence had relevance prior to the
mid '60s when cars had a single brake system (not split), but I don'
feel it matters on today's split systems with all of the ABS bundle of
snakes in there.

I still do the rears first, since they are the longest bleed times. I
doubt it would even matter if you did the fronts first. The easiest way
would be to do one side first, actually, but I just jack up the whole
rear end, then the whole front end.

IMHO, getting all the air out doesn't have anything to do with the
sequence, it's the procedure.

No offense to your techs, but I put that advice in the "mechanic's urban
legend" category.
