RPO for HD brakes on Gen II W-body?

[IRONDOG442]

I strongly suspect that the 2001 Intrigue I just parted out has HD brakes, the rotors on all four sides look new too. What is the RPO for this option?

Just measure the rotors.

I dont want to measure the fucking rotors I want the god damned RPO! Someone here has to know it! The wheels are on the car it is easier to look at the RPO decal on the decklid. Since this car is equipped with PCS I "think" it has the HD brake system. The system integrates four wheel-speed sensors, a steering angle detector, a yaw sensor, and a hydraulic power unit. It is supposed to help drivers maintain control in case of emergency maneuvers or heavy braking.

I called the dealership to find out and by the way it's JB9 and JL9 for standard Oldsmobile Intrigues, and JA9 for HD application.

 

JL4 is PCS
