So its looking like £9 for a button.

And/or £200 for one caliper. Looks like the motor and caliper is one unit?

Might I as well just change both calipers at the same time, going on the rule of, once ones gone the other wont be far behind?
Also, change the button even if its not broken, just because its old, and pretty cheap anyway?
f**k it - Might as well to the f**king timing belt while I'm at it eh. Can you buy those on Amazon?
