My brake system is shot! Neither front or rear works. I had new front brakes done about a year ago and they worked well up until this week. Compress the lever………. No brakes. An entire system for this atv is off the charts price wise, estimates are more expensive than all four brakes on my truck!!!!!! Rear caliper is beyond repair and so is the rotor. Any way to isolate the front brake? To do front and rear is estimated at around $700!!! All registered and insured but can’t ride!
