I have an 85 F250 XLT lariat which currently has a brake leak somewhere on the front drivers side. (It leaks all over the left front frame rail.) It looks dry around the master cylinder, (was replaced by mechanic, don't know if they did it right?).
Anyway the wettest part I can find is where the lines split from that metal connector. I thought the brake lines going to the back of the truck looked loose so I tightened it and it seemed to make the brakes work again but the reservoir level dropped and it seems to be leaking again. If anyone has had the same problem as me I would appreciate any advice I can get.
