Review on BlueSunshine Front and Back Disk Brake Kit - 160mm for 🚲 80cc Gas Motorized Bicycle - Freewheel Threaded Hubs - 48mm Hole Distance by Brian Sitton

They didn't suit me. I installed them correctly and the piston just withstood any pressure. This means that after careful, perfect adjustment, the lever has reached the handlebars. I will say this, I have a very heavy bike. I often go down the mountain. So if you like easy riding on level ground, they might suit you. But if you are serious about riding, DO NOT buy them. Just bite the bullet and spend your money on Avid branded brake calipers and pads. They're not cheap, but you're not going to die either. So you decide what matters most, your $50 life. If you buy these I can't stress enough that they aren't even half decent working brakes.
