I have an old service bulletin for the 380.

Incorrect specifications (almost the whole brake section) in the workshop manual.

somebody please let me know where/how to upload the pdf.

The most important bit is the manual states WRONGLY
Front Brake Disc
Standard value 26.0mm
Minimum limit 24.4mm

Rear Brake Disc
Standard value 10.0mm
Minimum limit 8.4mm


The CORRECT values are

Front Brake Disc
Standard value 28.0mm
Minimum limit 26.4mm

Rear Brake Disc
Standard value 18.0mm
Minimum limit 16.4mm


The pad measurement values are also incorrect
