Topic: 1974 CB750 K4 rear drum to disk brake conversion

[JonathanHValencia]

Good afternoon folks,

Question. I swapped hubs and wheel on the back of my cb750, this called for a brake swap. The new hub calls for a Brembo P32 caliper, Rotor and such. I have the parts, just unsure how I would connect this new cylinder to my current rear brake pedal. If anybody has experienced this any advice would help. It may be a given but I have no clue. Thank you in advance.

You need a separate rear master cylinder, often found in more modern rear sets if you want to go the easy route. Else, buy an MC and mount one up.

Hey Cali J,

I did buy a new MC. Only thing I’m missing is the line for the caliper to MC. But I’m just unsure where the new MC goes and how it connects to my pedal.
