I have a 05 sportster 1200 custom and when I press on my foot brake ,my brake lite wont come on only if I use my hand brake it will work. I want to ck the rear fluid but i am not sure if the bike has to be straight up or does if have to been on the kick stand. Any suggestion will help. It show a little above low on the kick stand .Also what is the correct fluid level , it shows low and high on the side cover
