I have everything installed but I have a question for you guys. The front rubber brake lines provided are the same part number, but that is not a real big issue. My concern is the way the block fits to the caliper. The block at the end of the rubber brake hose is mounted sandwiched between two copper washers and held down with a bolt that allows brake fluid to p*** through it In my experience the block should fit snuggly against the ridge on the caliper so it cannot rotate. Or only rotate in the direction that would tighten the bolt. The block on the end of these hoses can spin in both directions and it concerns me, is that an issue for you guys?
