Where can I find the official Shimano service manual?

Troubleshooting
Brake lever feels loose or wobbly after installation.
Ensure all internal lever components are correctly seated and the main pivot bolt is tightened to Shimano's specified torque. Re-check the service manual for proper assembly order.
Brake lever is stiff or doesn't return properly.
Verify that the lever member is installed correctly and not binding. Check for any obstructions or debris. Ensure the brake system has been properly bled, as air in the lines can affect lever feel.
Brake fluid is leaking from the lever assembly.
This could indicate improper installation or damage to seals. Re-examine the assembly process, ensuring all seals are correctly positioned and undamaged. If leakage persists, professional inspection is advised.
