I have little to no mechanical experiance. is it hard to change the front brakes or should i just pay someone to do it?

 

You've got 4 ATV's and have never changed brakes? If you are going to run to a shop every time you need work, you'll go broke.

Buy an after-market manual, they help a lot. You'll need metric wrenches and sockets for quad work too.

For the fronts, take off the wheels, then the spindle nut that holds the drum on. The drum may bind coming off, you just need to work it. The shoes are hold together by springs that slip over like a stud. That's it, reassemble and adjust your cable
