he`s right
when you bleed brakes its always the farthest side first, so it would go right front, left rear, left front, right rear, like that,
this is what i would and i make it a ahbit when i do brakes
when you have the caliper off the bracket, i always clean the mount points, on the bracket, clean the mount point on the caliper, then i put just alittle bit of anti seize on all the mounting points, and i always have the rotors cut, always
so when you put the new cliips in the bracket, put alittle anti sieze on those too it wont hurt, i do a mounting kit too should come with new caliper bolts, habit of mine too, same thing with the x-pattern brake system, push the farthest piston back in, and leave the master cylinder closed
the rear shoes, very easy to do espicialy on a gm, remove the drum get a couple can of brake cleaner and clean the crap out of the rear brake system, if you look at the bottom of the backing plate you will see the star adjuster, spin it out to make the shoes go wider spin it back it to make the shoes adjust in, as your doing this put the drum back on and you want the drum to have just enough drag to stop it on its own
oh ya i also put alittle anti sieze on the backing plate where the shoes sit
you could also have a bad wheel clyinder in the rear, you will see it too and the shoes should slide if you push on the top of them back and forth
real simple so simple i taught mrs.bdyman gm brakes so you can too
