I recently installed a set of the new (2013) brake levers made available as an aftermarket upgrade from Brompton. I did a little step-by-step for anyone interested in seeing what is involved in swapping the levers. It's been a few weeks since I did this, so I hope my recall is correct.

Original brake levers |
Step 1: Have your bike unfolded, and on a bike stand if possible.
Step 2: Loosen the 10mm bolt that retains the brake cable and loosen the cable.
Step 3: Cut off the crimp on the brake cable using heavy duty cable cutters.
Step 4: Remove handle grips if necessary. This may require cutting them off.
(Since I have a p-type handlebars I didn’t need to remove them)
Step 5: Loosen the bolts on the old brake levers and gear levers using the 2.5mm and 3mm hex keys.
Step 6: Slide off the old brake and gear levers.
Step 7: Pull the brake cables out of their housings.
Step 8: Thread a new brake cable through the new brake levers and the old brake cable housings.
Step 9: Reverse steps 6 - 4.
Step 10: Squeeze the brake caliper and re-tighten the 10mm nut to lock down the brake cable.
Step 11. Adjust the tension required to squeeze the brakes.
Step 12. Cut the excess cable length and crimp.
The brake levers are a good upgrade from the previous version...if I ever need to, I can now do a skid stop!
