How to get bearings

Ok, well you take out the wheel, remove the lid from the center of the drum (with a screwdriver or something similar), you will see the nut that is for a key 30 and take it out, give it a few blows through the front of the drum (well -set and dry blows) to take off the shoes, if you still do not get the drum, the hand brake may be very tense and you brake shooter), once outside, you will need a round of round tips that closes, to remove the "circli" that you will see the inner part of the drum. This you can do at home, the only problem is that you need a press for sacrum. The reverse. It proceeds to pass a sandpaper to the shoes and the drum so that there is no rest (oil, fat, etc.) I hope it will help you (it is not a laborious job) if you need anything else do not hesitate to ask. A greeting.
