None of these fittings actually fits on my brake handle screw port to add oil
This is so frustrating. None of these yellow screw ons actually fit into my super73 z miami brake handle port. They either just sit in it, which allows oil to seep all over the place, or are too big or too small. It says it fits all major brands, tektro etc. And mine is tektro. Im just trying to get my brakes to freaking work again. Its pissing me off.
