This is the second time my rear foot break has slowly quite working, first time I replace the foot master cylinder and bleed the air out and work fine, now back to square one I don't even use the rear break that often, can't be ware out all ready? I even took the safety part out of the transmission so I don't need to push the foot break down to shift from high and park. Thought this might save some ware and tar on the master cylinder, well didt work. Anybody have some input on this problem, some help would be great. New master cylinder is like $80 ouch Thanks everyone

 

this is an on going issues w/ the rear foot brake on the polaris as they are pretty much used for an emergancy brake then an every day brake. one of the things i have found is if you dont use them they tend to loose thier prime (so to speak) and will have to pressure. try putting an heavy weight on the brake pedal over night and then check it after you have taken the weight off. sometimes it works in making the brake work again. you could bleed them agiain like alot of people do but it still doesnt stay after awhile. imo.

 

Problem solved, I bleed the foot master cylinder and works like new again, don't understand how air gets in the lines thanks for the help stendori.

 

unless you have either an empty res. or a hole in the line or loose fitting there isnt any way air should be getting into the brake system at all. glad its a simple fix.
