About a month ago I swapped a 2001 rear end with E-locker into my '96 Tacoma. The 2001 rear end came without brakes, so I swapped my old brakes into the new axle. I only bought the truck 2 months ago, and had not wheeled with it until after the swap, so I don't know whether the parking brake has always been weak, or not. Any ways, the brake works okay on slight to mild hills, but wouldn't stop the truck on steep hills. I have made numerous adjustments, checked the brakes, made more adjustments, checked the brakes again, but it doesn't help. All the specs are okay as per my FSM, including the number of clicks on the handle, etc. The cable is tight as well. The shoes are about 50% worn. The self adjusting wheel turns well when the drum is removed, but there is not enough play for it to adjust while the drum is on, which tells me that it is properly adjusted. I've wheeled for many years, and my parking brake has always managed to stop the truck on a steep hill, i.e. lock the wheels, but with this truck, it goes downhill very fast when I let go of the brakes, even with the parking brake pulled to the hilt. The drums are perfectly smooth and do not need resurfacing. Are the shoes just dirty? Is there something I can clean them with? Anything else wrong? Please help. Thanks. Gary
