Good afternoon,
Noise when cold could be from the material itself with the pads. It all depends on the type of brake pads were used and if the rotor surface is correct. When you replace pads, the rotors should be either resurfaced or replaced. For the cost, I suggest replacing with new.

REMOVAL AND INSTALLATION OF BRAKE PAD
Removal
- If shims are rusted or show peeling of the rubber coat, replace them with new shims.
- Whenever the brake pads are replaced, the inner shim, the outer shim and the shim cover have to be replaced as a set.
1. Remove master cylinder reservoir cap.

3. Suspend the cylinder body with wire. Then remove pads with retainers, inner and outer shims and pad return springs.
Installation
1. Apply Molykote AS880N grease between pad plate and shim, shim and shim cover, and shim cover and piston.
2. Attach the inner shim and shim cover to the inner pad and attach the outer shim to the outer pad.

3. Apply grease to the contact surface of pad retainer with the pads, then attach the pad retainer and pads to the torque member. Make sure the upper pad retainer end is inserted through the loop on the audible wear indicator as shown.

4. Install the cylinder body to the torque member.
5. Insert a main pin bolt (on the lower side) and tighten it to specification. Refer to BR-21, "Component".
6. Inspect fluid level, then install master cylinder reservoir cap.
7. Check the brakes for drag.
CAUTION: Burnish the brake contact surfaces after refinishing or replacing brake rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
