Brembo Master Cylinder - 4J30+18

cheekytoad · Sep 10, 2008

Hello there,

Can anyone help??

I've be given a brand new front master cylinder.

Only problem is, i don't know its application!

Was told by the person i bought it off, that its millie fitment.

Need dust seal, lever & reservoir for it.

The REF number under lever mount is 4J30+18

Demon tweeks don't know!
Brembo don't have a number?
HHHEEEELLLLPP

the first four digits are just manufacture date. - 30th oct 2004

the 18 i am guessing is leverage ratio.

-first digit = year of manufacture
-second digit = month (A = Jan, B = Feb, C = Mar, etc...)
-last two digits = day of the month

google 'Brembo master cylinder' matey, theres a few UK suppliers, who sell rebuild kits.
I have done both clutch and brake and I have a spare lever. The rest you can pick up online. They make a HUGE difference.
cheers Ck
Post a pic mate, I can tell you if my lever will fit it.

PPS-just noticed you didnt refer to Radial in your post..so if its not a radial M/c, please ignore my last post.
try intobikes.co.uk for parts( or harris performance.)
cheers
