wheel cylinders dont make a noise, however, wheel bearings make exactly the noise you describe. (the beariing collapses, teh wheel cocks over a few degrees and the disk rubs against the caliper puttin the brakes on.
yes its dangerous. but a new wheel bearing is 20 or so quid, and i doubt as if you could do it yourself... if you continue to drive it like this itll scrap teh wheel hub, caliper and anythng else attached. and the possibility of the wheelberring collapsing and locking the wheel solid is a scary thought i wouldnt want to entertain.
good luck.

How do you know that it is the brake cylinder that has seized?
1. Try driving slowly, then (taking your hands off the steering wheel) apply the brakes sharply. If the brake cylinder has seized then the brakes will not apply on that side and the car will veer towards the side which is braking correctly.
2. Assuming that the steering did not veer, then the cylinder is probably doing its job correctly. You could have a bit of stone wedged between the disc and the pad housing. Try driving backwards somewhere safe and jerking the brakes, this could shock the stone out.
3. Does the whine occur at all speeds? Try jacking the car up at that corner (prefarably on an axle stand) and turn the wheel gently (making sure the other wheels are chocked so that the car cannot move). Is there a rumbling noise? then the screech is coming from your wheel bearing - get it changed before the bearing collapses..

the best thing is to take it to a shop but if you want to do it your self jack up the front remove the tire u will need a metric socket set I'm guess in g around a 14 or 15mm and a ratchet take the top of the caliper off and push the piston back with a c-clamp but be care full not to damage it it it moves with a c clamp then it is not stuck and u probably have other issues like a wheel bearing

Cylinder seizing usually comes from rust, moisture in the brake fluid. You should replace the seized cylinder, and flush the entire brake system with fresh brake fluid.
It is very dangerous as an emergency maneuver will result in random wheel locking.

TAKE THE WHEEL OFF, MOUNTS TO CALIPER, ON THE BACK SIDE OF CALIPER THE BLEEDER VALVE OPEN IT, NOW TAKE A 6-12 INCH C -CLAMP OR HAMMER WOOD END AND DRAW IT BACK. NOW AS YOU CHECK, WATCH THE CYLINDER IT SHOULD GO BACK WITH SOME EFFORT .
NOW IF IT DOESN'T, TAKE THE LINE TO CALIPER OFF
IT IS A FLEX TYPE LINE, HAVE SOMEONE PUSH THE BRAKE PEDAL AS YOU WATCH FLUID FLOW.
note : as you try to move caliper back take the brake reservoir cap off
YES IF IT IS NOT FIXED YOU WILL WRECK LOST BRAKES IN FRONT IS WORST THAN LOSING IN REAR
WHEN YOU BRAKE IT WILL PULL TO THE SIDE THAT IS GRABBING LEFT OR RIGHT

If it were "seized" it would not turn....(if its a drum brake)it would be locked up...after driving for a while . ...stop and feel the wheel...if it is hot you need to get the wheel off(if its a drumbrake) and pour some automatic transmission fluid on the brakes shoes to"deglaze" them...if its a disc brake..and you can see a 'groove" cutting into disc you need new pads....and if you are not mechanical...get a friend to help.I f you are rich go to a brake shop........aaarrrgghhh...aaarggghhhh

Check that you haven't picked up a stone and its caught between the disc and pad or caliper. Feel the wheel after a drive, is it hotter than the other side, if so it's rubbing and probably seized. A new caliper may be required,

There might be a rebuild kit avalible to rebuild the brake cyl. If not replace it and don't forget to bleed all your brakes. If you drive with a bad cyl you might end up with brake fade or pedal to the floor possibly causing an accident. Also check your brake lining is it in ggod shape?

I would have thought that the best answer would be to replace it with a new one
