You will need to check your front and back brakes.
If there is no noise just vibration when braking, you probably have rotor runnout.
This happens when people use impact wrench insted of torque wrench to tighten lug nuts.
That can deform the rotor and can cause vibration when braking.
Have the rotors checked and keep me updated.
If there is runnout, replace rotor and brake pads.

Hi there,

Thank you for the donation,

This can often be a brake rotor problem, have them re machined first, this often solves the problem,
