With a 5mm Allen wrench in your left hand, slightly loosen the outer nut by turning it in a counterclockwise motion.

While loosening the outer nut with the Allen wrench counterclockwise, support the brake pad with your right hand under it to counterbalance the force.

The brake pad setup will naturally fall down after slight loosening.

Quickly put the wrench aside and fully loosen the outer nut and following washers with your left thumb and index finger.

Remember the sequence they were assembled and keep the rest of your left fingers cupped under to prevent displacement of the components if they fall.

Take out the brake pad by using your right fingers to tilt down the pad and adjacent washers, keeping the washer sequence in mind again.
