Step-by-step explanation:

In order to loosen a bleeder valve, the following steps can be used

Step 1; Break the taper at the bleeder valve base and the corrosion or rusts present on the threads by tapping on the bleeder valve end with a steel hammer

Step 2; Tap the bleeder valve with a 6-point socket or wrench in the clockwise or tightening direction

Step 3; Tap the bleeder valve with the same 6-point socket or wrench in the counterclockwise or loosening direction in order to loosen it

Step 4; Repeat the above steps until the bleeder valve is loose.
