I remember what them Highlifter studs look like now , the spacer is made into the stud , totally different than the Super ATV , mine do thread into the ring and are nothing more than a long bolt with threads all the way and a slip on spacer to achieve the distance --- did you contact Highlifter to see if they will sell you studs ? Highlifter is here in my home state Louisiana , USA
Instead of removing the banjo fitting and using your finger to check for pressure and take a chance of introducing more air into the system , pinch the hose and pump against it , it will tell you quick if you mater is good or not ----- as far as bleeding the farthest away caliper , which caliper is farther from the master , that really doesn't make a difference on the 450 , there is a tee in the middle and one a-arm night be 1 inch longer than the other , try this procedure :
You need two pinch pliers to do this procedure , if you don't have them , then small vise grips will work , if you are using vise grips use a piece of rubber or cardboard to make a u-shaped hose protector so the teeth don't damage the hose ,first pinch the hose right out of the master , if the master is good it will make the lever hard with one maybe two pumps ( first time ) at the most , if it test good then leave the pliers there , attach another pair pf pliers on one side of the tee , blocking off one side , so that you are only working with one side at a time ---- here is the technique , pump the lever till you feel pressure then with your other hand release the pliers, when the pressure on the lever releases and the lever touches the handle bar , re-pinch the pliers before letting the lever go , then pump the lever till pressure is achieved and repeat the previous procedure , so what you are doing is force feeding pressure thru the hose , a pump at a time , then it helps to have another person to start bleeding the bleeder valve , when you feel you have pressure to one side , then move the pinch pliers to the other side of the tee and repeat on that side
