Brake Fluid Bleeder

I’ve had this brake fluid bleeder for quite a while now.
It’s a great tool that lets you swap fluid with a quick blast of air ★
The rubber piece you stick on the nipple at the tip breaks right away—it’s the worst—and there are no replacement parts available.
It’s one of those sell-it-and-forget-it racing tools, so I’m not buying from that place again!
Well then
 

 
Darn it! It won’t suck at all!
I took it apart to check how it works ★
There’s rust or something—gunk clogging up the passages!
I cleaned out the inside completely
 

 
It works now! Saved myself from buying a new one ★
People say, “I wish the hose was transparent,”
But I chose black on purpose!
 

 
Saturday’s weather looks iffy.
I’d really like to do a complete fluid swap this weekend.
