Those springs are only on the Navigators and maybe some of the lower level hybrids like the 7000, but not sure. A 7.6fx should have good solid brakes.
I think the idea on the Navigators is to soften the power of the front brake so people can't send themselves over the handlebars. Those bikes are made for occassional riders.
Oil is good, grease is better.
