Also, before putting the caliper back down on the new pads, you will have to use some very big channel lock pliers (or a big 'c' clamp) to squeeze the caliper piston all the way in.

IMPORTANT....
You should crack open the air bleed screw to do this, to let the fluid release out so the piston will go in. The reason for this is to NOT force the fluid back up the line, which may send debri into the antilock brake solenoids, and/or master cylinder.

NOTE....
Also, do not ever let the caliper hang by the flex line. It can crack the inside of it, and cause a NO brakes situation (and/or leak).

If you ever have the caliper all the way unbolted, use a coat hanger to wire it up on the chassis so you don't damage the line.

Note...me, I've only done 500+ brake jobs.

Also....for nice hands, better hours, more $$, ...become a doctor or lawyer (like Waylon Jennings said, "mommas, don't let your babies grow up to be cowboys, let 'em be Drs. and lawyers and such".)
Its too late for me, I'm a cowboy !
