Rear brake - stuck on....

Back to the parts list then

 

I would contact your local Suzuki dealer and seek a master cylinder kit for your bike.

 

I think the part you are referring to is part #2 on page 152 of the microfiche (parts diagram)

Unfortunately the next page doesn't show the actual part number or name which is annoying.


Any idea what they are worth?

 

Not certain mate, I have seen kits for $45.00+shipping but alas not for the Across.
Call your local dealer tomorrow and ask the question.
