Step 2: Manufacturing of a knockout device
Start by making a knock-out device, if you do not already have one. First, draw a line on a
wooden board with a distance of 20mm from the outer edge of the board. Now drill a 5mm
diameter hole in the board at the 20mm distance from the edge. The knockout device is
ready for use.
Step 3: Disassembly of the existing lever
Now disassemble the existing brake lever. Slightly tighten the brake lever and remove the
BAT cover or screw by compressing it axially and turning the bayonet catch 90°. Remove
the spring and the bayonet catch and set both aside. Using a screwdriver or a pointed ob-
ject, detach the brake cover from the brake lever body unit and set it aside with the adhe-
sive surface facing upwards.
Note: The previous steps do not apply to brake models without a cover, i.e. Carbotecture models
such as the MT5.
Now place the brake lever body unit on the knock-out device in such a way that the brake
lever replicates the left-hand brake side of a brake system mounted on the handlebar.
Note: The pin should only be knocked out in this direction.
Now knock out the pin with the punch until you can remove the lever and the pin still
remains in the brake lever body. If you knock the pin out completely, make sure that the
mounting direction is correct when knocking the pin back in.
