I have a 2000 Mercedes CLK430 that set for 2 years and the emergency brakes froze on it and I got one rear wheel completely free and the other rear wheel still had a little little grinding in it and button freed up completely but I took it for a test drive and every time I would press the accelerator hard the car would want to sway back and forth in the rear end. What could cause this?

In the anti sway system I believe there's 5 links per side on that car somtimes the rubber mounting points can wear out break and if that happens its really dangerous becuase it looses quite alot of stability back there (typical on cars that have sat for a while)
I wouldn't drive it if thats the case especially at any considerable speed
Its probably best at this point to take it to a shop and put it up on a lift so it cam be properly inspected you can see everything when its suspended in the air
So yeah with somthing that dangerous it would be a great idea to have it checked and diagnosed asap...
Good luck hop this helps
