Oil everywhere

Just finished for the day, got the front brake shoes off and they are covered with a thick oily sludge (along with the back plate and the wheel cylinders). I guess the oil must have been coming from the wheel bearing oils seals - but I won't know until I dig a bit deeper. On a positive note though the wheel cylinders work fine although I damaged the rubber boots getting off the shoes - so I don't need to replace the cylinders.
