after an embaresing amount of effort to get the rear flex line off...I finally goterdone. I remembered to put the brass washer back on the new line and about to attatch the other end that goes through the bracket W/slide clip. Just curiouse. what purpose does that clip serve? Also is there any tricks to removing the two front flex lines ? Which end should I undue first? The end at the calliper or the one that goes to the hard line?
