There is no adjustment for piston position on hydraulic brakes. Hydraulic brakes have a built in mechanism to retract the pistons slightly when the brake lever is released. The pistons are mounted in flexible rubber seals that deform as the pistons are pushed forward. The seals then pull the pistons back as fluid pressure is released. The pistons also slip ...

The system is designed to have the lever bleed screw displace some oil as it's reinstalled. In other words, the lever end wants to be completely full at the end, and there is not supposed to be an air gap there In the too little fluid direction, there is some tolerance for an air gap before symptoms begin, but ideally you wouldn't have any. If by chance ...

It sounds like your pistons are failing to retract when the brake lever is released. The mechanism used in bicycle hydraulic brakes to advance the pistons as the pads wear and to retract the pistons slightly when the brake lever is released is flexible rubber seals that surround the pistons. The seals deform as the pistons are pushed forward then pull the ...

My only important recommendation here is that if you get a carbon fork, ensure you get a full carbon fork. The bonded carbon forks with alloy steerers have been known to separate over time. People have died from this (Trek bike). Hydraulic brakes are the best, and not something you can replace easily later. But I've got friends with mechanical discs that ...

There's very likely something wrong that's causing a fluid leak. Hose connection, piston damage, or some other mechanical defect. They did the prudent thing before by seeing if it was a one-off/fluke situation, but now it's likely proven that it's not. What's really needed at this point is for a mechanic to inspect the hose connections in case that's where ...

A couple of things I would advice one. Firstly, from my understanding hybrid bikes tend to be very upright and commonly front suspension. Have you looked at any touring bikes? Hydrauclic brakes: Yes, they are usually better than mechanical ones. Although there are some very good mechanical ones too, look at TRP's Spyre or Hy-Rd for example. Hyraulic ...
