how to bleed brand new calipers

[h.e.a.t.]

when bleeding brand new calipers, is it the same exact process as bleeding old brakes? Do you bleed each brake individually as you change them? How do you know when a new caliper is air free?

Same procedure, you keep bleeding until you don't get anymore air out.

Ok. Cool. Should I bleed them individually as I change them or should I change all 4 of them and then begin the bleeding proces?

Either way is fine. If your going to replace all of them I would bleed the brakes before you switch them out until you have new fluid coming out all of them. Then change all 4 and bleed again. That way none of the old nasty fluid gets into the new calipers.

would he also have to bleed the master cylinder? or do you just have to do that if you change the MC. i know i had to bleed all the breaks and MC when i changed the MC a few years back.

As long as the master cylinder doesn't go dry he shouldn't have to bleed it. That is a good point though, keep an eye on the level while your changing out the calipers and top off as necessary.

I'm also curious to know if the truck should be running or shut off while pumping the brake pedal? I've seen some people saying on and some say off. I always thought that you were supposed to have it running while bleeding and shut off when refilling the fluid.

I've always had mine off, it's the way my dad has always done it.
