Brake Question
I have a 2000 S500 and I think there's something wrong with my brakes.
the problem that i am having is that it is very hard to push down on the brake pedal. I have a 99 E300 and when I push on the brake pedal in that car, it's very easy, doesn't take much muscle to push the brake pedal.
On the other hand, the S500, I really have to push the on the brake pedal really hard to stop the car. I kow that if I had air in the brake lines, then the pedal would be very soft, but what makes it very hard to push down on?
Any help would be appreciated.
Thanks
