The OEM husky brake reservoir and it seems like there’s something missing. Has anyone done this one yet. The cap won’t fit in place over the existing plastic/rubber membrane and I don’t think I should take it out. I don’t want to guess at this because brakes are important 😫. Please explain this to me.
As you can see above, there is a part that protrudes deeper than the outer sealing face. It won’t insert into the membrane, so..
