Default Help...C5 Z06 brake bleeder question

Hi guys, I was trying to flush the brake fluid on my ‘03 C5 Z06 and had a really hard time loosening the bleeder screw on the calipers. I tried to loosen it but was afraid I’d strip the screws if I had tried too hard.

The bleeder screw in the rear caliper is inside so I was also afraid I did it in the wrong direction. Because the screw is on the inside I turned it left from inside the car or right if I see it from outside the car looking at the caliper.

Any tricks that I can use. This is not supposed to be this hard

put a shallow 6 point socket on it to crack it loose but don't fully loosen it... once it's cracked loose you can snug it back up then put your hose over the bleeder and use a wrench to open it

Damned bleeder are easy to twist off. If it doesn't want cooperate I would put some PB Blaster on it and let it soak for a day or two.

Will there be any issue spraying penetrant like PB blaster on to the caliper?

I wouldn't soak the caliper with it, just put a little on the bleeder.
