How do i bleed the brakes on my 1996 gmc suburban

SOURCE: bleeding rear drum brakes

Take a small drill bit and clean out the center hole of both bleed screws (make sure you get all the way down into the hole, but don't go into the metal at the end.) Then, spray a good solvent into holes and on threads. Give some time for the solvent to soak in.
Put a six point box wrench on the bleeder then tap on the end of bleeder with a hammer. Keep doing this till it comes loose when turning the wrench. Don't use excessive force but don't be afraid to use enough force to get it to turn. Doing this, you will crush the tip of the bleeder, but that will not harm the "business end" Don't use vise grips on bleeders. At best you will damage flanks of nut portion, at worse, you will snap them off. Once you have removed bleeder, clean all rust off, make sure passageway is clear and re-install. If you do manage to break a bleeder, they can be drilled out, but it must be done carefully...if you damage threads or end seat it's officially junk. Bleeder screws are usually available at most parts stores...and, wheel cylinders are not very expensive if you need to replace one. Hope this helps!

Why were the brake lines replaced?

Sounds like the mastercylinder may have run dry. You have to bench bleed the master and then DO NOT allow fluid to run low, while bleeding brakes...

if master cylinder runs low on fluid and air gets in, almost impossible to bleed with out releasing the lines and bleed master it self.

Yes there is another way to do it but go slow and do it wright
Bleed by using the screw nut on the pipes you just fitted by.
Pump pedal 3times fast and hold down get someone to clamp all 2 hoses (1F/1brake pipe over rear axle) with small G clamps and then undo pipe nut on the one without clamp when pedal on floor lock up and do again ,when done 2 times put clamp from other side to the 1 you just done and do the same again to that side, when Front done take clamp from rear pipe and put on front and to the same bleeding to the rear BUT
pump up 3 times and open both nuts togeather and tighten both togeather and do the rear 4 times not 2, ANDTop up M/Cylinder every time , you might find jacking up rear of car is a lot better to remove air

One man suction bleeder from the calipers with top off the reservoir and keep it full when you **** fluid out the caliper.
