You need to change rubber brake line hose from caliper to frame they rot from inside.
Thank-You!! That was the problem and now everything is working fine.
If you open the bleeder and it releases pressure, follow the steel line back to see if it is pinched somewhere.
HELLO IF YOU HAVE TAKEN OFF THE TWO BOLTS AND STILL WONT COME OFF USE A SCREW DRIVER AND PRY THE CALIPER UP FROM BETWEEN THE ROTOR AND CALIPER ALSO YOU CAN PUSH THE CALIPER BACK TOWARDS THE INNER SPRING BETWEEN THE CALIPER AND ROTOR SITS THIS WILL PUSH THE CALIPER BACK AND GIVE YOU EXTRA CLEARANCE TO PULL UP THE CALIPER
Probably has a sticky brake caliper or sticky brake caliper sliders. Who ever replaced the brake pads should have seen that.
Why do caliper bolts back out on a Chevy K5 Blazer 4*4?
The caliper bolts may need lubricant as the caliper slides across the metal bolts it may squeak. Or overnight brake rotors can rust so when it first moves in the morning it may squeak.
The hose to the locked caliper is colapsing internaly and needs to be replaced.
Get a "U-clamp" that fits over the caliper and crank it down.
A 3/8" Allen wrench is used to r&r the caliper bolts.
It takes a 3/8" allen wrench to r & r that caliper bolt.
