your caliper is no good ,
had the same issue with my s-10 the caliper's piston isnt releasing
may be able to free it up by cleaning the posts and the inner piston.
but the easiest thing to to is replace the caliper

#22 of 28 Brake Problems after Ball Joint Change by johnbaum

Jan 10, 2012 (10:15 am)

I just replaced my Upper and Lower Ball Joints on both sides on my 98 Jimmy 4wd and a couple days later had an incident where after driving, stopped at the store. When I got back in the brake pedal went to the floor and I seemed to only have rear brakes. Thankfully, my trip was all uphill to get home so I wasn't too concerned but once I applied the brakes to turn, I once again had full pedal and the brake light went out. Initially I thought that I may have damaged a brake line during the ball joint change and that it was leaking but no leak and MC is full. I have heard of internal brake line failure but this usually causes the caliper to lock up. In the process of changing the ball joints, I did have to remove the Calipers from the Spindle and had to slightly compress the calipers to remove them but once pumped up they seemed ok until this happened. Could this be a MC or Proportioning Valve problem? I live in WV Mountains so brakes and good ones are important.

I had the same problem with my 2000 Jimmy. The ABS sensor was bad in the left hub. Had hub replaced (the sensor is part of the hub assembly and can't be individually replaced. Now everything works fine.

there is just a metal clip on ur push rod little flat screw driver wedge it in and pry out clip should fall out as it is slotted then remove the plastic brake lite actuator
