Re: disk vs drum pedal effort
In my opinion, manual disc brakes require a lot more pedal pressure than manual drum brakes. This is because bendix drum brakes are self-energizing. Design features in the shoe attachments cause the rotation of the drum to dramatically increase the clamping force against the drums beyond what is applied at the pedal. Earlier style Huck brakes and disc brakes do not provide this self-energizing benefit. To multiply clamping force in these systems a comparable increase in pedal pressure is required.
A person without back problems may find manual disc brakes acceptable, but for someone like me with chronic back pain a booster in the disc brake system eventually became mandatory.
