1991yamaha 4 wheeler; BIG BEAR 350 4X4; How do I ajust the brakes?the bakes have tighten . Feels like the brake is engagedat all times.

If it is the front brakes, you'll have to remove the wheel cyclinders, they tend to seize up and don't retract.
You can buy new ones or clean yours, provided they aren't leaking.
If they are leaking you'll have to replace the rubber caps.
Takes approx 2 hours to do both sides.

Since its a 1991 i would replace the brake fluid as well.

If its rear brakes - hydraulic - check the floowing:
Remove the caliper and stick a big wide screwdriver between the pads and pry them apart.
Reassemble. Sometimes the pads stick to the rotor if e-brake was left on for a while.
Cost only your time and about ten minutes.


If its drum brakes that are sticking, check that the cable isn't adjusted too tight first.
If cable seems fine then remove the drum and look at the pivot arm, it may need to be removed and then grease the hole it rides(turns) in.So it returns, The spring on the outside of the pivot arm makes it return so make sure that spring is on too.

That should free up your stuck brakes

I just got done doing this to three different 4 wheelers that were sitting for a while.
