My Shimano Zee rear brake is leaking/getting air in the lines (I believe through the lever). It results in extremely inconsistent level pull and sometimes a serious lack of power. Sometimes, a very slight pull will be enough to nearly lock up the rear wheel, but then 5 seconds later, pulling it to the bar will only result in a minor slowdown. It gets to be pretty sketchy sometimes.
Anyhow, I figure I'll go ahead and replace it/upgrade and am really eying the Hope V4s in red. So far I can't find any but have found a few of the E4s. From what I can find, basically, the only difference is that the E4s have two "small" pistons, whereas the V4 has one set of big and one set of small pistons, which gives more power.
At a weight of around 155 lbs without gear like
hope tech 4 e4 vs v4, I mainly ride in the park with runs lasting 3-4 minutes, but also occasionally go up north for some more serious downhill riding. I'm wondering if the E4s would provide enough braking power for me, or if it's better to wait until the V4s come back in stock, or even consider getting a different option altogether?
