Rubber tip on the brake rod

Sounds like some ppl think brake fluid is going to get into hole in master cylinder and deteriorate rubber ring???? If that the case you need to change the master cylinder. Duh. This isn't rocket science here folks.

Where are all the threads no rubber ring car wrecked ppl got killed? Anyone???

As far as excessive shipping, parts vendors have extreme crazy high over head for building, labor, taxes, loading unloading trucks, online store costs on and on and on. Yeah I wish they could lose money on shipping too....
