Hi

I replace my left-front boots and two rotor on my Honda Accord 92. Then my ABS gets problem. When I start moving forward, at certain low speed, ABS start working (NO BRAKE PRESSED), I feel the viberation from ABS. Then the viberation gone after that speed. When I press the brake to stop, at the same low speed, ABS start working again (Road condition is very good). No ABS warning light. My mechanic check, he guess it is from my sensor. but there is no ABS light.

What is really happen? Is it because of some damage from changing the boots and rotor? What should I do? Now I drive the car without ABS. Any recommed, thanks in advance
