CMadison and EZT, I'm planning to take my Z to auto shop, probably Nissan service center and ask. I think I have to refill the brake fluid up to max before change the brake pad but don't know which one is right for me. So, wondering how much money they going to charge on me to replace the brake pad, refill the brake fluid and solutions for another problems on my Z. Thanks.
