Review on 🔄 Dorman M39634 Brake Master Cylinder: New and High-Performance Replacement by Ronald Orear

Put this on my 1990 Ford E150. There was a leak from the start. I tightened and tightened the brake lines several times to stop the dripping. In the end it turned out that the problem was not in the brake line fittings but in the plug with the O-ring in the bottom of the block. Saw one at the parts store and they don't have a leaking bolt feature. If you're looking for a molding that sticks out at the bottom and has a screw covering the hole, either buy another one or put some kind of sealant on the steps before installing. The O-ring alone didn't help me.
