Getting rid of air pockets after replacing the front brake disc pads

Quite correct. And for those imagination-challenged, here's a picture of a 2005 Lexus GX470 front caliper:

You can see the mounting "ears" at the bottom (need a BIG wrench from behind to get the bolts loose), fluid inlet has a green plug, bleeder screw is gold colored.

Nice find MB. I'm beginning to think the OP had Marsh Monster's help on this brake job.

On this model and (I think) all Toyota 4 piston fixed calipers minus Land Cruiser and Lexus' LX4x0 clone, brake tubing goes from the caliper to the hose mounted on the knuckle. One should remove the spring clip at the hose's female end and finagle/hang the caliper out of the way if one desires to keep the hydraulic system closed.

My question is -- how does splitting these calipers apart not put up an obvious "don't do that" flag, especially after fluid comes out? Wouldn't that eventually signal that something was wrong besides it being a "new" unfamiliar brake design to the OP?

Over the weekend, I bleeded the brake and it is working fine now.

I didn't want to remove the entire caliper because I worried that I might break the tubing. Next time when I have to do it again, I may still stay with the same method I did it now that I understand how to bleed the air out the system.

I replace a pair of new rotors too this time. The dealer had recommended resurfacing the old rotors. I think I will keep the old rotors so next time I will have them resurfaced before I replace the pad.

Looking at the picture of the calipers from the link, I didn't see a bleeder valve in the rear caliper. Any idea?

If you are referring to splitting the caliper in half, I wouldn't suggest it. I already wrote what you should do if you want to remove the caliper without opening the hydraulic system; it's in the post you just responding to (and it's quoted above).

A fine idea.

What rear caliper? Look dude, rest assured that there is a bleeder screw on *all* calipers. Your bleeder screws specifically are 10mm hex front and rear, and they are near the top of the caliper(s) as viewed in their mounted position(s), pointing upward. They really are there, or they *were* there but possibly have been broken or deformed. The screw is clearly visible in the link provided by Master Blaster, plus he detailed it as gold colored in his post. Of course, that is a pic of a front caliper... not a rear caliper.
