i have a 2005 F-350 XL truck that has 68,XXX miles i recently changed the rear brake pads and about a week later the rear passenger side is leaking brake fluid.The fluid is slowly dripping from the bottom caliper bolt but i am not sure if there are seals in this area. the driver side is fine and the fluid is only leaking from the bottom caliper bolt not the top.

 

The leak is probably coming from the seal around the piston and running down the lower bolt. There is no fluid near the bolt itself and I can't imagine a caliper housing with any kind of a defect that could leak in that spot. You most likely will need to replace the caliper.

 

thanks for the info i will take a look at the caliper then.
