Rear Brake Change problem -ASAP

When replacing pads on rear, I have to use a special socket attachment tool to turn-in the single piston.

Driver's side worked with no problem

The passenger side however is turning but not receeding. I've attempted to apply some minor pressure to push piston in a little. This did not help.

ANY IDEAS or SUGGESTIONS ???


THis should have been a simple gig...

NEVERMIND....

Hook up rachet attachment to 3/8" impact wrench... the jostling did something to help.

Back to work...
