Please explain the brake bleeding sequence.
Isn't the usual sequence from farthest to closest to the master cylinder? This would mean RR, LR, RF, LF. Now I'm reading from some reputable members' post that the correct sequence, at least for the C5, is RR, LF, LR, RF. I believe this is how the manual recommends doing it.
Thanks!

You are correct, the manual lists the sequence as:
RR / LF / LR / RF
This is because the car has two separate hydraulic outputs from the Master Cylinder to the calipers. Each circuit feeds diagonally opposed wheels, so that if you have a failure in one circuit, you still have 50 percent of your brakes.

For those with older C5's -- On my '98 the proper sequence is RR,LR,RF,LF.
Only 2001+ have the new bleed sequence, although it may have started in 2000.

Very interesting. I think it is in 2001 that the brake bias began to be controlled by the ABS unit (electronic brake distribution). This may be related to the switch in bleeding sequence.
