If you had that much pad to start and ended at the wear sensor I assume you're running hard on the oem pads. I had a similar experience where my oem pads overheated and melted away rather quicly, but I also had fade, a soft pedal and increased travel. Pagid yellows was the cure.
Assuming all your hard braking is in a straight line, track configuration should have a minimal effect on pad wear. If
PSM was off we can rule that out as a factor (and it was unlikely for the front anyway). You may have a sticky caliper piston or similar mechanical issue. As a start, I'd go for a 15-20 min drive and bring the car to an easy stop. Feel the wheels or calipers (or measure rotor temps w/an infrared) - both fronts should be about the same temp. If the left front is much hotter you may have a pad hanging up against the rotor.

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
