Ask him how often he has to add brake fluid. A leak that bad needs to be fixed, whether it's a rear hub grease seal or a brake- - - -either way, you're probably looking at a brake rebuild because the brake linings will be saturated, and there's no way to clean them up.
Have you factored in the cost of replacing those widowmaker rims into your offer? The one in that photo is definitely an RH-5 wheel.

I agree. I still can't understand how it is leaking so badly down the outside of the wheel if it is brake fluid.
Just about any truck I find is, most likely, going to have those rims, so it will always be a price factor.
Thanks for the info.
