car seems to be knocking (loud)and vibrating in the front (sounds like it is on the middle or right side) whenever i try to accelerate over 24mph.
However in the mornings when I am traveling to work (mostly on the freeway) I am able to accelerate as usual with no issues.
This problem seems to occur while driving in the city and having to stop and start, could this be my brakes. I checked the calipers while the car was in neutral and they seem to be stuck, should i have some give and be able to move the caliper on the sliding pins.
Thanks
