I'm changing the seals on my non preload-adj WP forks for the first time. When I try to take the cover (the top of the fork when you are looking down at the fork on the bike) off I feel like I'm going to break something. I had the 20 mm wrench in a bench vise and I was pushing pretty hard on the 24 mm wrench on top. Am I missing something or should I just get a breaker bar? Thanks Unfortunately I'm not having any luck with the search function.
