I’m not sure what’s going on, but I’m having a hard time?
Every part I remove seems to have issues.

I’m working through it, wanting to wrap this up soon. <\/p>\n\n\n\n

Bikes that are 10-15 years old should
have their rear master checked. <\/h2>\n\n\n\n

The return port hole seems to be 0.5mm or smaller.
Such small holes can get clogged, which requires attention.

The inside of the rear master cylinder can corrode,
and when you step hard on it, it won’t return… this happens more often than you’d think.
Brakes are seriously scary (*\u00b4\u03c9\uff40*)

Older master cylinders often don’t have repair parts available anymore.
Users don’t have much choice…
Well, basically.
I’m not writing this as a maintenance business pitch, so…
If you take your time thinking about it, you’re the one who’ll suffer, so be careful. <\/p>\n\n\n\n

Button head M10-P1.25
09139-10004-000 (10*27) \u00a5134 <\/h2>\n\n\n\n

This is the right-side bolt for GSX-R models.
The left side is discontinued.
However, since the right one is longer, you can cut it and use it if needed.

It’s an inexpensive and somewhat rare bolt.
GSX-R owners should definitely stock up on these.
*The button head strips easily, so be careful. <\/p>\n\n\n\t\t

Kawasaki sells them individually, but Suzuki sells them as a set and even cheaper, so definitely check it out

Titanium bleeder nipples are the way to go. <\/h2>\n\n\n\n

Basically, iron bleeder nipples are rusted nearly 100% of the time.
In severe cases, they often break.
Lately, whenever I disassemble a caliper, I force titanium.

Since the original iron nipples cost quite a bit too, just add a little more for titanium.
Honestly, the peace of mind is completely different.
It looks nice too, very good. <\/p>\n\n\n\n
