Trying to remove harmonic balancer with a breaker bar and socket. I have someone stepping the brake with the car in 6th gear. I can't back out the bolt because the engine is turning. Is my clutch grabbing or is it slipping?

Thanks in advance.

Note to self. Must put lug bolts back in if your brakes lack the retaining screws...

Problem solved.

Hahaha, glad you got it figured out. I was trying to figure out how you were managing to get the brakes to slip as well as the clutch, but I didn't have a clue.
