Serow 225: Oh No!

Someone rode up to the shop on a Serow 225 with a passenger, so…
Before I could go inside…
I was about to politely turn them away and stepped outside when I saw M??
“Apparently the guy in back bought a super cheap Serow and the brakes don’t work, so take a look,” he said.
We don’t usually work on bikes without inspections, but… I guess we have to.
 

 
Yikes! There’s no brake fluid in it…
That’s genuinely dangerous.
Even after bleeding the brakes, something keeps dripping from the master cylinder…
Hmm…
 

 
Yikes! The inspection window is shot… and it’s all gummy too.
Like, am I supposed to fix this right now? That’s the vibe…
 

 
There’s no part available for this…
 

 
Filed down the cap and pressed it in—done.
You owe me one! ★
