Big statement but bigger [/fatter] than you 🤗
6’6” and 124kg at last count, ideal weight is normally 110-112kg.
I had it serviced and he put shit pads on, which I accepted because I didn’t know better. First proper downhill they stopped doing anything much at all which was terrifying, I stopped by wearing down my heels on the tarmac.
Took it to another shop immediately who replaced the pads with shimano, checked the fluid, and gave it a once over and they’ve been ok ever since, but I got discs because I wanted them to be good not ok.
I am more at the doing 80kph and wanting to stop asap end than the dragging the brakes end.

What road bike do you have? The frame and fork will determine how big a rotor you can run.
What make and model of brakes are you running?
Not all bike shops are created equal, you might have a shitty bleed that's stopping you getting full power.
Bigger rotors will give the most benefit but you probably won't be able to get bigger than 160mm on the frame but the fork might be able to take 180mm.I'm 100kg give or take a kilo or two depending on which way the wind is blowing.
I run 160mm discs on my road bike with hope rx4 calipers and they stop me ok. -
Bear in mind that I'm 90+ kg but I'm also riding around with a loaded bike (touring, racing, etc) so system weight is more likely well over 100kg.
Were the brakes you used actually bedded in? Disc brakes don't work if the rotors are fresh, they need some hard stops to work properly.
I'd check the frame and fork can actually take bigger rotors before thinking that will solve things. Are there actually adapters for flat mount that will do bigger than 160mm?
How big are you? I've run 160mm front and rear Ultegra and have ridden everywhere with that setup. What pads are you using? How do you brake? Are you scared and dragging the brakes or doing 100kph and wondering why you don't stop in 10m?
