I replaced brake fluid with new ATE blue. Bled the brake by Motive power bleeder @15 psi. I know the front discs are worned out (with lips on the inner and outer edges), and braking power is weak. I'll replace the discs soon. But I'm puzzled by the following behavior: on going reverse, there is literally very little braking power. Much worse comparing to going forward. Why????
