DPB Brake System Stiffness Test
Validates all 4 brake lines by measuring DPB plunger stroke values and validating that none are blocked, have air or leakage
TEST-SELF_BRAKE_X_DPB-ESP-SYSTEM-CHECK
ModelY/tasks/TEST_BRAKE_X_STIFFNESS-TEST-PRESSURE-BURNISHED
Measures the brake system stiffness of burnished brakes and tests the brake pedal switch. Stiffness threshold is selected based on chassis and brake hardware type.

TEST-SELF_BRAKE_X_DPB-ESP-SYSTEM-CHECK
Applies pressure to each individual corner in turn to compare the output values and validate the brakes. If executing with DIAG_LINK_ACTIVE then EPBs will release one at a time, which is required if CHECK_SWAPPED_REAR_LINES is true.
TEST-SELF_BRAKE_X_DPB-ESP-CORNER-STIFFNESS-TEST
Applies pressure to each individual corner in turn to compare the output values and validate the brakes. If executing with DIAG_LINK_ACTIVE then EPBs will release one at a time, which is required if CHECK_SWAPPED_REAR_LINES is true.
TEST-SELF_BRAKE_X_DPB-ESP-CHECK-REAR-CROSSED-LINES
Measures the brake system stiffness. Select burnished or unburnished to determine the pass/fail threshold. Stiffness threshold is selected based on chassis and brake hardware type. Stiffness by wheel circuit is also measured, but not used for pass/fail.
