I had just recently did my front brakes on my S10 Blazer. The issue I am having is from replacing the calipers I now have no pedal what so ever. My friend and I keep bleeding the system and we keep getting air in the front. We did the proper procedure for bleeding and the backs are not producing air (but they are not shooting fluid out only kinda just pouring out).

The old caliper was frozen probably for a good while.

 

Have you tried gravity bleeding them? If your not sure what that means, make sure the master is full, open up the bleeder furthest away from the master cyl ( right rear) let it drain by itself without pressing the pedal, let it run for a sec and then close it, open up the left rear and do the same, close it then go to the right front, do the same , then close it and go to the left front do the same procedure there and then close it..when bleeding brakes ya have to start the furthest away from the master..Ive never had any problems doing it that way..check the fluid again if that works for ya.. If it doesnt i may be able to take a peek at it at my friends shop in farmingdale!!! if your familiar with Toledo street off baiting hollow the shop name is Long Island Customs Address # 78A I`ll prob be going there mon after 12pm...Lemmeknow if that repair helps ya..

 

Found the problem. Was deemed a bad master. Seemed that since the old caliper was so badly frozen, it boiled and bubbled the fluid so when I got rid of that pressure when changing the caliper it just let the master finally give out.

Gotta love these trucks only 45 for a new master.
