Hub to rotor torque spec

Post by JT191 »

Does anyone know the torque specification for attaching the front brake rotor to the hub?

My PR manual covers only drum brakes.
The JR manuals omit this spec (but go into great detail about how much grease is required for every bearing component down to the hundredth of a gram).
The PF manual says 5 kg-mm or 36 ft. lb.

Is the PF spec close to the PR spec?

I got a response from someone in Japan. The answer was 4.3-5.5 m-kg.
