I'm in the process of doing my rear brakes and when I pulled off the drum on the passanger side the brake workings in between the shoes is covered in axle grease, a lot of it!! The wheel cylinders don't appear to be leaking and I'm not loosing brake fluid so I'm fairly sure it axle grease. So...how do you go about replacing the axle seals and does it require a press?
