Replacing my drum brakes because of an unfortunate over usage of penetrating oil around axle. Basically both drums got doused and the oil got into them. Now overnight they barely hold the jeep on level ground. Any ideas before I buy new pads and drums? I've hit em hard with brake cleaner and ran the E-brake a little while moving. Neither did much. If they are doomed. Is there a better brand of drum brakes to buy or do the box store drums do the job?
