What brake do you have, specifically? what did you pay for the Bike, if it's part of a low price point bike ,
I dont see the issue.
Get better, like, Koolstop Pads and that will make a big difference.

FWIW, Magura has re introduced the Hydraulic rim brake for road bikes, looks more aero
than the double acting slave cylinder, dual pivot they used to make..

the ones mounting on V posts work really well.
