Order of ABS brake bleed

[wirehairs]

I've installed all new SS lines and am now filling/bleeding the system.  The manual indicates to do the front right, then front left, then the rear.  I'm curious why that is?  I'm assuming it's because of the ABS and the ability of air to move through the system?  I've done the clutch line OK, but yeah, I've got clear fluid (no bubbles) coming out both front bleed valves, but not enough pressure on the brake pistons yet.  I'm just assuming I have to run a LOT of fluid through there to get the little bubbles hiding somewhere.

1) Yes, Right-Left-Rear is the correct way. Why? Cuz it sez so.    Yes, you also use a lot of brake fluid to do it.  I've gone through 3 small bottles (or more?) doing it.

2) If there are no signs of leaks, and they're still mushy then maybe the new SS lines are exposing faults within the master cylinders - previuosly masked by the old expanding rubber line.  Assuming that you did not rebuild the cylinders before you put on the new SS lines.

3) Were the calipers rebuilt lately or during this process?  If not, maybe take a look at their condition.  "but not enough pressure on the brake pistons yet" may indicate a sticking caliper(s).

The first year I owned my '92 ABS one front caliper siezed open on me while braking coming off a freway ramp.  A bit of a pucker moment while I pumped the front brake and it unstuck itself.  So an immediate rebuild was the result.

There might be some other reasons but these are the main ones I can think of.

Thanks for the reply, Paul.  Yeah, I rebuilt the 3 master cylinders, as well as all the calipers, so hopefully, it's just a little air I need to convince out of there!

RPM's offering of a syringe for a "reserve bleed" has got me wondering if bubbles tend to stick around the calipers. 

I'll update this post when I finally succeed in this "fun" endeavor.
