Rear wheel cylinders and brake lines on rear axle. I was wirering up a trailer hitch harness and noticed dampness at the bottom of l/r backing plate. So i got real close and tried to smell it to see what it was. I just put rear seals and bearings in 1000 miles ago, so was hoping it wasnt that. I couldn't really smell anything, then noticed a touch of wetness on the rim. Wiped it off, along with the paint....lolol....only fluid that'll do that is brakefluid. Bingo. We have a winner. Brakes never felt good anyhow. I guess i know why now. Both were only working on one side of the cylinder. ohwell
