I'm very new to hydraulic brakes and am not impressed with the stopping power. I wonder if I need new fluid? I can bottom out the levers, the braking force is really no better than rim brakes thru the range of motion.

I bought the bike in November 2022 and it only has about 1100 miles on it, but it sat on the showroom floor for just over a year. I don't know if it uses mineral or DOT. SRAM Red AXS HRD brakes.

Should I buy the tools and learn to purge? Or do I expect too much?
