Rear Caliper Removal

[positron1]

When removing the rear calipers/lines and you have to drain the brake fluid, where should you drain it from? The caliper bleeding screw, the brake line banjo fitting on the caliper or the brake line where it connects to the chassis?

I almost want to ask why you are removing them in the first place. If you are installing new or different calipers I would leave the line and caliper connected as long as possible so as not to drain the Master Cylinder and have to re-bleed all your lines.

More info on what you are doing pleez!

I'm about to upgrade to Z32 brakes only days from now so I'm reading up and making sure I have every little detail lined up. So the best thing to do is to pop the line off the chassis and install the new caliper with pre-attached line right after?

Yes, wait to unhook the old caliper until you are ready to install the new one otherwise you will leak all the brake fluid out and have to re-bleed the whole set-up rather than just the rear 2.

See...something else I did not know. Since I am only doing the rear, then I will only have to bleed the rear and not all four calipers correct?

I'd bleed the whole system. It'd suck to press the brakes and your foot drop to the floor and keep going the same speed....

Yeah, that might make you have a bad day.
