seal is bad

looking at the brake area, there is a seal outside of the drum on the final drive top shaft that keeps the 90 wt gear lube in the final drive. hard to get much thru that seal, level is way down in the case. on the other side of the brake drum the shaft goes into the transmission- differential. there is a seal on that side also. not uncommon to get some oil past that. some have 90 wt in the transmission, some have hydraulic fluid.--- under the drum there is a 1 inch hole. clean it out real good, blow, wash, blow, wash ,etc. clean real good. if you have a leak, you will see a small puddle on the floor below the hole the next day. clean the drum, install new brakes and your o.k. small leak will drip at the hole and not in the shoes.
