Removal pedal on a standard cycle.
Place spanner on flats or Allen key in recess
While looking at the cycle side on
If possible, with the spanner /Allen key pointing rearwards at 2 o’clock position
Push the spanner downwards.
I had a Brompton folding pedal done uo in a bike shop with a long Torque Wrench.https://turbobobbicycleblog.wordpress.c ... and-money/
When I took the crank off to which it was attached I tried to remove the pedal with a smaller of the two Allen key recess, with Allen key socket I sheared the tool.
I suspect there may be corrosion
So I place the component in place in a container and spayed with T2 lubricant
Half many weeks tied again with no success
Then I tried using a larger socket Allen key with a long tough wench with extension
I inspected all the threads and saw no damage
I cleaned all parts and place in my part box
I should have removed the pedal whilst still on the bike. This would permit more leverage.
