1999 Suzuki King Quad Front right brake locked

[gohndd]

Hey guys, I have a 1999 king quad. The right front brake locks up when I squeeze the lever. I can loosen bleed screw, fluid will come out and it unlocks. I'm thinking maybe wheel cylinder. Any suggestions?

It is a drum brake but it has a twin piston caliper, it sounds like the caliper is hanging up, i would pull it off lube it up a bit and see if that helps, the pistons may be sticking also, go ahead and check that out while you have it off, or you could replace it, thats what i did , they are fairly cheap, actually cheaper than the OEM kit,  and i really didnt want to mess around rebuilding it.

It will be a defective rubber hose, the one to that wheel. They swell up inside so that the pressure you apply with the lever is enough to apply the brakes, but the return pressure, which in the case of a drum brake is a spring, and in the case of a disc brake is only the flex of the rubber piston seal, isn't enough to force the fluid back.

Thanks guys, new caliper fixed it. Noticed other side rim is a little warm after riding, gonna change caliper on that side too.

Great, glad you got it fixed, new calipers do wonders for these old machines.

Good stuff..

 The hose was my next try, but the calipers were cheap and turned out to be the problem. The other front wheel was warm after a ride while the one I fixed was cool, although it isn't locking up. Probably the caliper on that side too. Thanks for the advice anyway. The hoses will probably be next.

Yeah! They are cheap and come with new shoes, i think the last ones i bought, which was a 2 pack to sevice both sides, ended up being  about 28.00 and included pads. Dont  know how they will hold up, we will see.
