you need to bleed both at the same time.
it would be better to buy a vaccum/brake pump.
$40.00. make a t hose for the rear calipers

Both bleeders on the same caliper, is what i mean.
on the rear.

There should be two rear bleed screws opposite each other on the top of the calipers. I just installed "Speedbleeders" and they work fine. Still a pain to get all of the air out, but at least I can do it myself.

Bleeding the rears can be easier if you raise the front of the car while doing them (or park up a hill!).

We are doing this today after completing a power brake conversion this week. The rear has three bleeder valves on ours two on top and one on the outside bottom. The front only has one bleeder on the iside top. Will let you know how it goes.

just went through this last week... I missed the inside rear and bled the others...thought I had 'em, but still NO pedeal....then read posts about proper sequence and "found" the rear inside bleeders... went through sequence and pushed out a huge air bubble on front.... man I got some brakes now! better than I had hoped.

forgot to say.... I just took a small aquarium hose and ran down thru a small hole in the top of a plastic soda bottle attached to the bleeder screws ...had a buddy help me pump the pedal... worked like a charm.

Shoddy work on the part of the rebuilder. Outside bottom should be a plug, not a bleed screw. How in hell can you get air out of a bleed screw that is lower than the rest of the caliper? This kind of workmanship would cause me to question the rest of the rebuild.

I would be most interested in your answer concerning Delco-Moraines, as my originals had only 2 bleed screws. I still think it is shoddy work on the rebuilders part.

I'm gonna be working on the car tomorrow (detailing for Corvettes on the Square in Independence Mo next weekend -mandatory shameless plug for the KCCA ) and i will try to snap a pic for ya. When i tried to bleed them for myself the 1st time, i coulda swore that there were 2 upper and 1 lower bleeders on there, but like I said I have been mistaken before...

As I stated, if you have 3 bleed screws on a rear caliper, it has to be a rebuilt unit from a less than reputable rebuilder. Nowhere, in any GM manuals or literature that I have, do they show or mention 3 bleed screws on a rear caliper. As I said, how can you bleed air out of a caliper through a bleed screw that is lower than the top of the caliper??

As always, I am open to factual criticsm and comments.

I agree. Do the speedbleeders really work that well? I am in the process of bleeding mine now as I had to replace every #$@#%@#(& brake line. Of course front right caliper had the bleeder broken off. May just replace them all with speedbleeders if it's worth the cost.

A bleeder valve is cheaper than a plug.

I love mine. It takes only a couple of minutes to bleed each wheel and you're done. Plus, it's a single person job - no more begging the S/O to get in and work the brake...

I think it came from GM that way for some sort of universal fitment from left to right on halves...I'll look in the morning, but I think that mine do have 3 bleeders...and opening the lower one would be just short of stupid when bleeding brakes.. air goes to the top...

They are a bleeder with a one way check valve inside them. They let fluid out and not let the air in... they work really well if your'e a one man show.
