Hi guys,
            recently attempted to bleed by rear brakes, had some problem.

            there were tiny bubbles coming out non stop. realized the bleeding screw has some free play. So i went to get both of them changed.


even after changing the bleeding screws the problem of tiny bubbles appearing does not go away. Because even after changing the bleeding screws there is free play.


So Seems like the thread on the caliper or worn out or something like that.


Instead of changing the whole caliper any economical way of solving thing?
