I have a 2006 kazuma 90 deluxe from raceway atv.The front brakes keep locking up on my son.I took the calipers off compressed the pistons and reinstalled but it does not last long.Anyone have this problem or a remedy?I spoke with raceway and they said it "might" be the master cylinder so I ordered one.PLEASE HELP!

 

Does the calipier compress easy? If it does compress easy your problem may be a pad binding.

 

It does take some effort.You can hear the master cylinder make noise as I compress the piston.But it does it on both front calipers equally

 

Are the pads wearing evenly on the rear, both pads the same thickness?

 

yes they are even.The quad is still like new and only used about a dozen times around my yard.My son barely even used the brakes.
