My 09 V Roadster has a sticky handbrake that doesn’t always release well at all!
What’s the best way to fix it?
Thanks

 

Check the material on the hand brake pads, make sure adjustment of cables are even (# of threads or distances similar) how high or how many clicks at the lever? 5-7 should be in the hunt for correct adjustment. Sticky button or dry mechanism at handle. 1st thing to check is your procedure as some people are not used to the left hand. Sit on the sill and try your Right hand and see if that changes.

 

Do you want more or less threads showing to make it tighter (less clicks)?

 

Go big my friend. 22mm nut and you can count threads or use the wrench to judge distance for a quick check. Most stock build are started around that 22ish mm.
So try 25-30mm. Word of caution. Be aware of the inner pads as they tend to wear quicker.
