1150GS Rear brake master cylinder

[Two wheels good]

2002 R1150GS ABS, non servo.
My m\cyl is stamped FTE 544 5588; not a Brembo item. Diameter 14mm

Rear master cylinder leaking. Not a easy matter to find a new one - or used. Repair kits non-existent.

Has anyone used a part from another model?
The RT m\cyl looks identical but is separately listed. Will it fit?

yes i know it says 13 , but you won't notice it.
if thats not the correct layout, look at his other stuff , i think i put an 11 on my GS.
don't forget hole spacing.

Thanks, that's encouraging. Better price too.
Mine is "inline exit" but they stock that type too.

Is a copper pipe union the same diameter as a banjo bolt? I haven't removed mine yet.

The 1150RT version looks identical, ignore the length of the rod. example
But Sherlocks /Motoworks didn't offer that option. Maybe out of stock too?

Considering this one at the moment.

That's the one. I decided to email them first.
Another option turned-up, a new one in Austria. Avoiding Brexit delays and double VAT prompted me to spread the net wider.
Might yet be ready for the end of lockdown!

Below is 14.29mm off my 2002 R1150RS (ABS)

Was working fine when I replaced it for a 12mm non ABS unit to give more progressive braking when ABS removed. (Smaller the diameter the more progressive the braking feel)

If OP can use it, welcome to it

Thanks Ajay, very kind of you. Alas not of use to me - unless I refashion the ABS copper pipes. Yours is "side-exit".
But I'm hopeful I'm sorted with an OEM unused item.
BTW Helpful reply from Performoto on eBay. Bookmarked for future reference.

Glad you can get back on the road
