if you think the brakes are stuck on touch the drums and see if they are hot after you've been for a drive.
Alternatively just jack the car up and spin the wheels...

I agree with this diagnosis... Jack the rear of the car up, let the handbrake off, and grab the wheel at 9 and 3 then 12 and 6 (as if lookin at clock) - if you can feel play in the wheel when doin this then your bearings are shot.

I've done it prob about 3 or 4 times...
Costs about £20 tops for everything you need, usually more like £15...
Take off wheel, remove the little cap thing you see in the middle of the drum with a screwdriver. You'll see a castellated nut underneath with a split pin thru it. Take the pin out and the nut off along with the toothed washer underneath.
You'll now be able to remove the drum from the hub. If it doesn't wanna come off easily, pop your wheel back on, put a couple of bolts in and pull on the wheel, will come off a lot easier.
The front bearing will just drop out... you will have to prize off the rubber oil seal from the back of the drum (you'll know what I mean when you see it, round rubber washer thing in the middle) to get the inner bearing out.
Once you done this, use a flat bladed screwdriver and hammer to tap out the housings from the drum. If you clean away all the grease, you'll see a notch in the casting on the drum where you can get the screwdriver into to tap out the housing. Do this with both housings.
Then get your new housings, put some lubricant round their outer face, and on the inner face of the drum where they go, and drift them into place slowly. Take care not to let them go in at an angle, as this'll be a pain in the arse to straighten out.
Once you got the housings in, put grease onto them and around each bearing. Pop the bearings into place, then replace the rubber oil seal on the inside, usually get a new one with bearing kit. Put the drum and new bearings on, put the toothed washer back, then screw on the castellated nut ***FINGER TIGHT ONLY*** or your car will munch through your bearings in a matter of weeks (believe me, I know!)
When you've put the nut on, put the split pin back in (if the nut doesn't line up with the hole in the axle, unscrew it til it does. Then replace the grease cap, put your wheel back on, job done!
Don't think I missed anything, good luck! If you're still not sure, you can borrow a Haynes manual from local library usually...

In that case you just buy some grease for £2.99 in a big black tub, take off the bearing cap and pack it in with your fingers.

I'd get the races changed as well as just the roller bearings - your only doing half a job otherwise. As people said they might have dried out too. If they are worn you can actually just tighten the castle nut slightly...
Buy yourself a haynes manual, they are a must and will tell you all about virtually everything on the car...

No point changing bearings unless you change the races/housings too - bearings bed into their housings, so puttin a new bearing into a worn race may just wear the bearing out quicker...

I think I will just go into the local motor factors and tell them what I am doing and then let them give me what I need they are really good know what they are talking about, as for haynes I have one for the 2.0l 16v Calibra but the thing is it had brake disks so it makes it a bit fifferent to the corsa cos thats just drums if u know what I mean to a novice reading a haynes is the easy way but then reading one with disks when I dont have em would knacker me up
