Because our cars came with MC bleeders, so the bleeding sequence is different than without bleeders. I've done it both ways and have bleeders on my MC, the main objective as we all know if getting the air out of the system, this can be achieved either way of the bleeding sequence. I use a pneumatic bleeder, hooked up to my compressor and it'll get all air bubbles out regardless on which wheel I start at.
I bleed mine the same way but I also have a cheap kit that allows me to attach tube to bleeder and then put tube into cylinder filled with brake fluid. This ensures no air comes back into the system.
Make sure you continually top up MC.

Yeah, I do something like that too. I attach clear tubes to each bleeder and put the other ends in empty water bottles. Then keep pumping and refilling while opening each bleeder. I stop when each bottle has several inches collected and the tube is full and I feel like it was sufficient
I thought I would resurrect this old question (below) by Harold. I've been replacing some of my brake hydraulics parts (MC, WCs, flex lines) and planning the bleeding of the system. There must be a technical reason the Pontiac engineers chose a nearest to furthest bleeding sequence rather than the common furthest to nearest practice while engineers of similar brake systems on other GM lines did not. It may not really matter that much but why wouldn't all GM product lines be consistent?
Ramair68, I don't think it is the MC bleeders because they are only on Tempest and Firebird power brakes.

Wonder why they tell you to do it in that order? Should it be done according to our Service Manual?

Jimmy, Get a bleeder kit. Makes the job very easy.
I looked at that Motive pressure bleeder but did not see where they have an adapter for our old master cylinder design. I ended up getting a vacuum bleeder from Eastwood but I'm unhappy with it because air gets sucked into it at the bleeders likely from both the threads and from a poor seal of the tool's adapters on the bleeder fitting. I can't tell when the system's air bubbles end because of the air leaking in at the fittings. I will probably use gravity first and followup with a helper hitting the brakes the old way I used to do it.
The real question is, why did Pontiac engineering recommend the closest wheel first sequence instead of the usual most distant wheel first?
