Brake question and a hangover. Need help

[FL318is]

I have a huge hangover so I hope this discription makes sense.

When I depress the brake pedal down to stop the car it makes a "shudder" feel towrds the bottom of the travel.  At first it only did it as I was braking while turning left.  Now I notice as the car has set.  I think the pads are good.  Fluid is good.

Is there something I should look at?

My car does that at very low speeds in puddles and down at the beach when pulling into sandy parking spots. I assumed it was just the ABS kicking in because the front wheels locked under braking. It's all I have ever thought it to be.

Heres the latest.

I think its the ABS,  Yesterday my dash anti-lock light came on.  There were no more symptoms.  Shut the car off, restart, light off and symptoms returned.  CA bushing is good
