Brake Bleeding Sequence
I have always known to bleed brakes from farthest to nearest to the master cyclinder. For example, start at right rear, then left rear, right front and finally to left front. I will be changing calipers soon and read in the service manual that bleeding should be done in this order, right rear, left front, left rear and then right front. Obviously, GM wants it done their way, but can someone tell me why? Also, would bleeding the old fashion way be ok? I have read that many people do bleed farthest to nearest. I just want to get it done the "correct" way. Thanks for the help.

It has to do with the "ABS System" and there are two different methods.
The "ABS System" is located in the rear for 1997-1998 C5s and the correct brake sequence is Right Rear - Left Rear - Right Front - Left Front.
For all later models C5s, the "ABS System" is located in the engine compartment and the sequence is RR -LF - LR - RF. Your 2003 falls in this category.
