Replacing Rear Calipers - Suggestions on Bleeding
Replacing both rear calipers. Any suggestion on the best way to proceed so I don't spend the rest of my life chasing air bubbles out of the system? I guess I am mainly trying to find out if there are any special tips for dealing with the fact that the new calipers are completely empty.
Initial plan is
1. Remove majority of old fluid from MC reservoir.
2. Remove old rear calipers.
3. Allow old fluid to drain from lines.
4. Install new calipers.
5. Fill MC and bleed all 4 wheels using the gravity method.
If this info is already out there feel free to direct me to it. Searching revealed topics mainly concerning changing fluid not purging air out of new calipers.
Thanks

Press the brake pedal in all the way to 'seal' the system. It prevents the drawing down of the fluid like holding the top of a straw with water in it.
Then bleed the crap out of the system

Do not gravity bleed all 4 you will be getting air out of the system all day. Just do the two rear calipers you replaced, starting with the right rear. Suck out the old fluid from the MC and put in fresh fluid. Have a buddy pump up the pedal a couple times, crack the bleeder. Repeat.

Not too keen on doing the full unloaded stroke on the master cylinder as I have had problems with that generating seal leaks in the past so I will probably just use the vacuum pump to get most of the air out and then bleed as normal. Thanks for the help.

Why not bleed the brakes with the fresh fluid first.
Take vise grip pliers, cloth to wrap around the rubber brake line.
Change the caliper. Bleed the now new brake fluid into it.
Go finish the other rear caliper.

That is certainly the easiest but I am always afraid of damaging the brake line resulting in a leak or a collapsed line. I am sure that either failure is highly unlikely but after 13 years they may be getting a little crispy.

Im glad you are hesitant and are weary working on an S as you should be. This aint no civic! But have no fear, brake lines and the bleeders hold up for a LONG time unless you just drive in salty conditions 24/7. Just get a 10mm line wrench and proceed with bleeding, new fluid in the MC. You'll be alright

For any one interested , here is how it went.
1. Removed calipers except for brake line connections.
2. Sucked old fluid out of master cylinder and filled with new.
3. Removed brake line from old caliper and installed on new caliper. It leaks a little fluid but not much.
4. Immediately connect Mity-Vac to bleed screw and suck air out until brake fluid comes out. (Don't know if this is necessary but since I have the vac I figured it would help speed things up.)
5. Assemble calipers and pads to car.
6. Gravity bleed per the usual method.
Pedal is rock solid. No problems. Only thing I had to deal with was a bunch of high spot on the piston faces of the re-man calipers where some one tore them up screwing them out. Nothing a file couldn't fix but way too ugly to install as received.
