my car fishtails when braking hard in a straight line please help
Hey everyone I am new here!
I drive a c180 w204 (2012) with 20k km! And just did my service b! So a few days ago i was driving at 120km/h then i needed to brake hard as soon as the Abs engaged the car started to fish tail from side to side then to the right if i wouldnt have released the brakes the car would have spinned! What is the problem ? I drove many other cars and never had such a problem please help thanks

It could be a variety of things. Assuming your cruise control and spedo work Id rule out wheel speed sensors, check the car for abs faults., if no faults present you may have sticking calipers or contaminated pads in the rear. If you ever changed your wheel or tire sizes that could maybe affect it but highly doubtful because there would be other symptoms. Id check the rear brakes mechanically, if everything checks out try a brake flush. If you still have this issue just take it to the dealer because it will most likely be an issue that requires a more in depth diagnosis.

abs issues?
also if you want to try to get into an open lot where you can duplicate the symptom, this time just stay on the brakes and control the vehicle as you normally would, if the vehicle stays in the same general trajectory and doesnt spin out or become uncontrollable it may just be a normal thing for that car.

get the car on a lift, look in the rear undercarrage at the suspension. make sure your torsional links are intact. when they break they allow the back end to wiggle under braking. i had the same issue with my w203 C32 AMG. if i hit the brakes the back end would go for a scary ride.
