having some trouble with both front brakes locking up after a ride once they are hot. what can cause this quad is an 89 trx250r .

once they lock up I crack the bleeders and they unlock .

sounds like a master cylinder ? or can it be a caliper adjustment ? thanks

Your slides are sticking or something is wrong with your lines not allowing the pistons to push back slightly. Either way, rebuild the calipers, everything is available from honda. Some others have said that everything except the body and bracket are exactly the same as 04/05 450r's.

look on a microfiche and there are the parts on it. You will need the two pin dust boots, 4 piston seals, and maybe new pistons. For the pistons, many use cr250r pistons, they are lighter and won't seize.
