2004 endeavor rr8r .The pedal is hard when applied and it seems to brake ok but as you get closer to a halt the brakes seem like they do not have the grip or stopping power.It can get harrier if it is a quick stop and has caught me off guard a few times and i feel like i am not going to stop in time.The coach was one owner with 32000 miles when i bought it and is was wondering if the shoes were glased but i have put quite a few miles on it since i bought it,has anyone have any idea what i need to check before i do not stop in time Thanks in advance
