Weird ac noise and problem

So recently ac went out I assume it's probably compressor so will replace that soon but I have noticed if I run the ac or even the heat my car will make this weird almost water drop sound and when car is at complete stop I can feel the brake pedal kinda of shake. I will try get video of noise but find it weird that it does this with both ac and heat.

If you’re at a stop and the brake pedal shakes and you hear a noise it’s the abs kicking on. Check for codes

Only code I get is the tire pressure sensor cause I got Aftermarket rims and have not put new sensors on yet would that cause abs issues?

The compressor may be putting to much drag on the motor causing the idle to drop to low to supply vacuum to the booster. You might want to unplug the compressor and see if that makes a difference.
