Analysis
1. Using appropriate software for the data acquisition device, plot the system pressure, wheel speed
and engine speed versus time.
2. As the system pressure increases (from applying the brakes), the engine speed and wheel speed will
start decreasing.
3. When the system pressure stops rising and remains constant, that pressure will be the PCOR setting.
The engine speed should remain constant during this period while the wheel speed continues to
decrease. See Graph below.
Adjustment
1. If adjustment is required, use a 3mm internal hex to hold the PCOR adjusting screw in place and use a
10mm wrench to loosen the PCOR lock nut. One full turn of the adjusting screw changes the PCOR
setting by approximately 90 Bar.
a) Turn adjusting screw clockwise to increase the PCOR setting.
b) Turn adjusting screw counterclockwise to decrease the PCOR setting.
2. Use a 3mm internal hex to hold the PCOR adjusting screw in place and use a 10mm wrench to tighten
the lock nut to 8 N-m [6 lbf-ft].
