Installing Rear Brake Pads On Your Alfetta, GTV6 OR Milano

Adjusting the pad-to-rotor clearance

The clearance between the pad surface and the rotor should be .004" / 0.1mm (the thickness of a Post-It note).

Driver's side outboard piston: Loosening (counter clock-wise) the 17mm lock-nut and rotating the (side-facing) 5mm allen-headed adjuster screw counter-clockwise pushes the piston toward the rotor (reducing the clearance between the pad and the rotor).

Driver's side inboard piston: Rotating the (rearward-facing) 7mm hex-head adjuster screw clockwise pushes the piston toward the rotor (reducing the clearance between the pad and the rotor).

Passenger's side inboard piston: Rotating the (rearward-facing) 7mm hex-head adjuster screw counter-clockwise pushes the piston toward the rotor (reducing the clearance between the pad and the rotor).

Passenger's side outboard piston: loosening (counter clock-wise) the 17mm lock-nut and rotating the (side-facing) 5mm allen-headed adjuster screw counter clock-wise pushes the piston toward the rotor (reducing the clearance between the pad and the rotor).

Do not— repeat, do not—run any of the adjuster screws all the way to a stop (all the way in or all the way out). Doing so will damage the o-ring and cause a leak. As soon you feel an adjuster screw bottoming out, stop turning it. You have just pressed the o-ring against the body of the caliper, or, in the case of the outboard adjusting screw, against the lock-nut. Further turning will cut the o-ring. Leaking adjuster screws are not covered under warranty.
