Hi Guy's,
Just for your information, had an intermittent problem with the parking brake.
I checked the switch, and inside there is a small peg which operates from the chrome P switch. If you pull out the peg, behind it is a small spring I stretched it a small amount, put all back together. Now the peg locates well with the rocker switch and works perfectly.
Not sure what a new one would have cost......
For your info mine was on a 2008 Flying Spur.
Take Care
Nigel.

 

Thanks for the tip Nigel.
