ykno like instead of slotting them or hole drilling them, cause that will just wear brakepads faster, or so i read, i had an idea.
how about you groove them in circles.. like this : so theres circular grooves going around , therefore increasing the surface area, like on an accordion if u can imagine..
i think this is a good idea.. i got it because my front left rotor looks like this right now for some reason.. i need to get it resurfaced i think
is this an idea or am i just a![]()
