I've got an early 2000's model Jamis with linear pull brakes that have a weird dampening spring on the pads. So as the pad contacts the rim the brake lever keeps advancing but the pad remains stationary. I have no idea what the purpose is for. I suspect they were an attempt at fixing something that never went over well because I do not see this feature on linear pull brakes anywhere else.

The brakes are Tektro "SU 20".

Anyway the brakes are kind of weak. I am not a lightweight rider, plus I carry commuting panniers.

Can anyone recommend a brake pad that is softer or more grippy? I need something to counterbalance the weakness of the brake.

P.S. If anyone can suggest a more appropriate forum. I am surpised there is no forum titled "general bike maintenance".
