so after bleeding my Tektro mineral oil brakes, the brakes appear to no longer be functional. when I depress the lever until it touches the handle bars. I am still able to spin the wheel. I think it wasn't a bad bleed as I feel as if I am applying a rather substantial amount of force to the lever. I am assuming the problem is mineral oil on the brake rotor/pads. I have already tried using an oven cleaner spray and soapy water to clean the rotor and changing the brake pads(to used ones) to no avail.
So my question is as follows: should I buy a brake cleaner and a set of new pads? or should I attempt to cut my losses and get the entire brake system replaced?
