The twizy brakes have the tendency to get stuck. The abrasion accumulates in the brake system an the component’s movement gets inhibited. Because english is not my native language, some technical terms will be wrong. If in doubt, clear those doubts before continuing.
hex key 5 (dont know if your size system is different)
wrench 13 (i use a socket wrench)
screw glue mediun strength (ie loctite)
and: steel brush, brush, cleaning cloth, work gloves
first apply handbrake firmly and secure the other front wheel with a wedge against moving. Lift twizy and take off the wheel. Remove the mud guard. You can do it with mounted mud guard, but you can work better with it removed. Feel your way along the mud guard’s rods to it’s screws, and loosen the three 13-screws.
You can see now the wheel reciever with the disc and the brake system. To get the pads out, the whole brake system has to be taken off.
Loosen the guide bolts with the hex key.
Dont take them out, just loosen them some turns. Make sure the hex kex is fully inserted, otherwise you will damage the bolts.
Now loosen the two 13-screws at the brake system’s back. They are next to the screw thread of the mud guard.
The brake system is now detached but cant be pulled from the disc. The disc forms out an edge with prevents that. You have to push the pads apart.
Position the screwdriver as shown and lever the pad sloooooooowly from the disc. Occasionally try if you can remove the brake system and continue levering if neccesarry.
