This 4 bar linkage ain't square enough 4 me
I've been thinking this over lately. The handbrake brake assembly shares it's existence in the BMW too as you know. It's only ever referred to as a parking brake in the manuals. But if their cars brakes, suffered total hyrdraulic failure, I bet they could pull-up with more confidence than us. Well me anyway. The handbrake applied braking energy is massively greater on the stock Bug than the somewhat puny Porsche set up- you agree?
My hanbrake is sweet, even on hills so it's only worth sharing my thoughts....
The input (profile of the cam at bottom of the handbrake cable) is not 'best suited' to the differential load response of the shoe spreader.
A much closer look at the geometry might turn something up. I suggest a handbrake lever, modified to compensate for the non tangentiality, for want of a better word, and maybe make an OEM cable be best fit?
