Brake help
I have a 85 F-250 with the 6.9. I recently replaced both wheel cylinders that where both leaking. After I replaced them my brake fluid level stayed steady. But after a week or so the fuild level started dropping. Not a a lot but where it would run out every week. Anyone have any ideas why or where it would be leaking.

Look under the truck, you probably have a leak.
Fill it up, and sit in the cab and pump the brakes for a minute or so, then look for wet spots or drips under the truck. May be quicker and easier if you have a helper. If you're underneath when they are pumping, safety glasses would be a smart idea to keep from getting brake fluid in your eyes.
Its possible you got a crappy wheel cylinder, but a rusted line or leak at a connection is very likely as well.

I checked both my cylinders and they aren't leaking. I've done some research and found that people have found out that it's in the master cylinder. They just took them back until the got one that wouldn't leak.
