I am looking for some help on a possible breaking issue I am having. Please note that I am not very technical. Anyway, the issue that I am having is that the car pulls to the left when braking. I took off the front left tire and examined the drum and brake parts. I noted that there is a seal in the drum that looks to be dented. If anyone has a part # for NAPA or NPD or somewhere I can find one. I also noted that when applying the brakes, the wheel brake cylinder (WBC) looks like it is not functioning properly. There is a 'rod' that moves out of the WBC when the brake is applied and the rod on the left side of the WBC moves in an upward direction. I am not sure if the rods are supposed to move straight out of the WBC or if they are supposed to move in an up and down motion. The rods also do not move simultaneously, the left side rod moves and then the right side rod moves. Any help here would be greatly appreciated.
