I bought a new gravel bike (Serious Grafix Pro) with SRAM hydraulic disc brakes. The rear one has very weak stopping power.
I can pull the right/rear brake lever completely to the handlebar and the pads just softly touch the rotor. So I'm wondering if I can just e.g. tighten a screw to make it more sensitive.
How can I adjust it? I found many Youtube videos, but none I needed.
Sorry for my lame question, not particularly strong for (not only) bike mechanics.
