I have had issues with ABS light for around a year where the light occasionally comes on and off. However, the brake pedal has been misbehaving only in the last two weeks and I am getting really concerned about this.

The braking issue according to my observations which may or may not be 100% accurate happens, only when:

1. The orange ABS light has not yet lightened up in dashboard;
2. I am driving at low speeds (5-10 mph);
3. I turn steering wheel and apply brakes at the same time.

Then the brake pedal *sometimes* is pulsing and the braking distance seems to increase quite dramatically. Then the ABS light turns on and brakes work normally for the rest of the time. It is not easy to reproduce this issue. On average it happens once every two days.

**Is the pulsing brake pedal necessarily an ABS issue?** I have been reading that ABS should not engage at low speeds, so it makes me think it may be something else.

**How can I temporarily disable ABS to prove or disprove that this is ABS issue?**

Car is Chevrolet Aveo 2007 sedan. The roads are dry hence ABS should not engage.

**Update#1: now also the red "brake" light occasionally turns on while driving even though parking brake is disengaged. Though the car seems to operate as before.**
