Replace Brompton folding pedal - what tool is needed? I've managed to completely break the folding left-hand pedal on my Brompton.  The bit where it fastens onto the crank* is fine, but the rest of it gone.

What tool(s) do I need to remove the broken pedal and fit a new one?

I'm asking this because I want to compare the price of doing it myself (pedal + tools) to the price of getting my local Brompton dealer to do it (pedal + labor + loss of self-respect).

Thanks.

*Please forgive me if my terminology is terribly wrong! :o
If it's a pre-2012 non-titanium Brompton, it takes a 24mm socket.  If it's a 2012 on-wards, it needs an 8mm Allen key.  The 2009 to 2012 titanium Brompton used a 10mm Allen key in a Ti pedal bolt.  The official Instructions are available on Brompton's site.

Very important: remember that the left hand pedal is left-threaded -- the reverse of normal. 

Note that pedals can get quite tight.  A standard 8mm Allen wrench might well not be enough leverage.  An 8mm Allen socket combined with a larger  socket wrench is a better tool.
