Shimano's Dual Control shift brake levers have the advantage over Campagnolo that scratched levers can be replaced quickly and easily. However, if the ratchet mechanism is defective, only the complete functional unit of the nine- and ten-speed levers can be replaced. We show the steps for repair
Degree of difficulty: for experienced screwdrivers
You will need:
- Excipients: Wooden board, spray oil
- Tool: Hexagon socket, punch, rubber mallet, Phillips and slotted screwdriver
GOOD TO KNOW
TIP:
The ratchet mechanism of Shimano's shift brake lever is very well sealed off from the outside. Lubricating the lever through the openings is only possible with a thin spray of oil.
TIP:
Due to design changes during series production, the disassembly of some levers may differ slightly from that shown here. Exploded views and exact descriptions of the available spare parts can be found onwww.paul-lange.de/ products/shimano/support.
TIP:
Disassemble the levers step by step and take a close look at the position of the parts before dismantling them. Lay the parts down in sequence to make it easier to reassemble them later.
