It's pretty easy to degrade the performance of brake systems. To start with, use the wrong pad. Changing to a good pad probably makes more difference than anything else - and conveniently is the cheapest improvement (other than cleaning the rims).

Next, in general, centerpulls have more leverage than sidepulls, and short arms have more leverage than long ones. Just the physics, ma'am. So, to degrade performance, use super-long arm side-pulls, like those found on certain beknighted BMX bikes. Whose operators are not known for big strong hands. Oh well, Darwin wins.

Third, levers vary almost 2:1 in their leverage, with Universals having very low leverage - and correspondingly high travel, and Weinmanns much better among the ones I've measured. Want less stopping power and a harder, firmer, feel? Install Universal levers.

Remember, more leverage will feel softer, since you can apply enough force to feel all the flex in the cables, calipers, mounts, etc.

605!........Is a better brake!....Better stopping power and so on........500>>>>>wIMpY! Me....Remember>>>>Flying down 9 into SANTA CRUZ!...Using Weinmann 500......Was like having NO BRAKES!....What was I THINKING?????????????????

   >> I am asking for comments comparing the performance of these two models. I understand this is subjective and many factors obtain yet, none-the-less, I'd welcome the feedback. I am concerned about the performance such as stopping power, feel, "snap" and such.
