I had an issue with the standard hand brake spring hitting the inside of the wheels.
I have had a small batch of springs made with 1 coil less. It's close but there is now clearance.
If anyone is interested please U2U.
Price is £18 per set including post and packaging

Close???????

I think it'll keep that part of the wheel clean. ! Lol
