For my new Zertec Handbrake. Its easy to get the old one off and unscrew the old button but how do you screw thw new one on as it is hard to get any purchase on the button to screw it on.
Use a rubber glove to hold the end piece (ooh er missus!!)and then push down and slowly turn at the same time - once you get the thread in the right place it will be easy and goes on very quickly - Hope it helps!! Neal S14 TVR
