Hey all im back.rear driver side caliper sticking time to time and while checking it out,the brakes gave out.put a new master cylinder on and brake line.got brakes but i still have the caliper sticking deal.i notice i have a leak on the abs thing where the line goes into the box.that line i believe goes to that sticking caliper.the leak causes a good bit of wetness but you cant see it leaking.does the abs thing need to be opened up or something and maybe replace a bad seal?i cant find a video to help me or anything and im scared to open it because i have been reading about some scanner thing needed for it.and help would be appreciated.
