Warped rotor

My car has been jerking/shaking when I brake for about a month now. I put it off for awhile since it wasn't too bad, did some research and am pretty sure it's a warped rotor, but now the shaking has gotten much worse and my appointment to get it fixed isn't until next week. If this is a warped rotor, can this be dangerous waiting so long to get it fixed? Can it damage my car? I just don't want the brakes to fail on me.

If it is shaking bad it is not safe to drive..
Since we can not see or feel it we can not tell what it is.
But remember the rotor could cracked or broken or somethng else may be causing the shake. Could have a wheel ready to fall of.

It is not dangerous unless the shaking is really violent. These are easy to change and you can probably do the job yourself and save a bunch of money. Simply jack the car up and support it with a jack stand or blocks. Remove the wheel and then remove the caliper by taking out the mounting bolts. Remove it from the rotor and then pull the rotor off. Clean the new one with brake cleaner and then install new pads. To do this, if open the bleeder screw on the back of the caliper and then push the piston back. Install new pads and reinstall the caliper and the bolts. You will need to bleed the brakes by pushing on the brake pedal and opening the bleeder screw until you get a good stream of clean brake fluid. Make sure you don't empty the master cylinder. Reinstall the wheel, lower the car and you are ready to do the other side. Of course if you don't have a garage and it is cold outside have someone else do it for you. Good Luck!

The shaking when appling the brakes is caused by the ABS, as it puts on/off the brakes.
can be a number of reasons:
1) Warped rotors
2) Misadjusted rear drum brakes or tensioner installed backwards, so front brakes need to compensate for rear brakes
3) ABS sensors bad
4) ABS sensors wet ( snow can build up on them and play havoke )
5) Pads not sitting right or clips broken
6) bad/bald tires in winter, as tires slide and ABS sees this and compensates
If when you apply brakes all the time or 90% time it can be rotor and pads, if conditions play effect it can be sensor or tires. If all the time brakes are not adjusted properly on rear and warped rotors on front as well.
By the way, sunfires and cavaliers are know for this type of braking issue.
