brake pedal kind of shaky
so the other day i was driving on a gravel rd pretty much just letting the car idle in drive and going like 5 mph because it was the speed limit through the park, but anyways i was covering the brake pedal not pushing it and i can feel like shaking pretty bad. Ive noticed this when im driving too and i cover the brake when im going through a bump part it does the same. What do u think it is? I looked underneath the steering wheel area where the brake pedal bolts onto this bracket or whatever and i cant figure it out. Any suggestions?
