Replaced brakes 6 months ago and started hearing noises. Took into shop and they replaced brake pads and rotors as they were already messed up. ABS light and stabilizer light still on so they said to replace calipers. Replaced them which made the noises go away. But when I hit my brakes it feels like pulses / grinding feel in brake pedal.
What would this mean I need to still change?

 

either your ABS is activating or the rotors are probably warped, brake calipers wouldn't cause abs/stabilitrac lights so you have multiple issues

 

Rotors are new. Replaced rotors and brake pads due to noises and ABS lights on. Once they replaced those 2 parts they said I needed to change calipers because one side wasn't releasing which is what caused pads and rotors to go bad so quick. So all items were changed today. Now lights are off and nothing's squeaking, but I notice the vibration pulses in brake pedal when stopping.
Could a improper bleeding cause this?

 

no
your getting false abs activation from a wheel speed sensor dropping out.

Yeah I just jacked up this morning and realized right side wheel was loose. So I'm ordering new hubs and hopefully that will solve it.

 

that will do it. good find.
