CN Code Master Cylinder
 

Hi All,

Can you tell me what a "CN" code master cylinder or brake booster goes to? The "CN" is a sticker tag that goes around the master cylinder cap bails.

Thanks,
Dave

Dave,
CN is the code used to identify the master cylinder and brake booster assembly for a 70 Chevelle with disc brakes.
GM used a cardboard tag on the check valve with the CN code and the sticker on the bail wire coded CN
on a BB coded master cylinder and 9391 part # booster.
Hope this helps,
Chris

Thank you Chris. Exactly what I needed to know.

Best,
Dave
