Corrosion. Ensure connector is fully installed into CCM.
Check Harness Connections at Artic Joint (if applicable).
Drag Fault could be from broken ground wire.
11. Verify Sensor Condition and Operation
Confirm correct Wheel End Location by unplugging Exterior
Sensor Connector (>60 sec) and confirm Sensor Fault at correct
wheel w/Diagnostic Tool (I.e. Front Left Wheel End
should show Sensor Fault on Axle 1 Left).
Inspect Sensor for damage or Signs of Corrosion.
Verify Sensor Voltage function. Check sensor voltage at
CCM connector with system power and wheels chocked.
Test green signal wire to black ground wire.
Brakes Released 0.1-1.99 VDC,
Brakes Applied >2.00 VDC.
Sensor Fault if <0.10 VDC after 60 Seconds.
Sensor Power: Red power wire to black ground wire. Voltage
should read >4.8 VDC.
Pressure Transducer: Inspect e-STROKE Pressure Transducer
and wiring. Use Diagnostic Tool to verify Pressure
Transducer read < 0.3 psi with NO brake application.
12. Inspect e-STROKE Brake Actuator
Piston Rod Reflective Target
Remove Brake Actuator and inspect Piston Rod Ball End
Reflective Target Material for Grease, Dirt or Damage.
Clean Grease from Piston Rod Reflective Targets with clean/
dry rag.
DO NOT use solvents.
☞NOTE:

- ✅【Application】This brake caliper press tool suits for disc brake, NOT for drum brake. The tool is equipped with 2 groups of push boards: 7.01x2.36"and 4.53x2.17".Smaller ones are suitable for disc brake system with twin and quad pistons fixed calipers, or single and twin pistons floating calipers. The bigger ones more fit for some sextuplet pistons fixed calipers. Also this ratcheting caliper spreader is designed to "push" the piston back, can not twist and compress, which some brakes need.
- ✅【Labor Saving】Brake repair brake spreading tool adopts 360 degree ratchet design, it is easy to get into place and use from any direction, also your hands will not get fatigued from the constant squeezing. The ratchet is in the centre of the dual piston brake caliper compressor, the two spreading plates keep parallel, make sure to spread the force on the caliper piston evenly, in case of caliper damage or pistons dislocation.
- ✅【Use-friendly】 Swing the long lever handle to expand and retract the spreading plates, and the positive and negative regulation is realized by flipping the reversing switch in the ratchet. Because of ratcheting mechanism, both spreading plates need pressure to start the ratchet, please squeeze them for the first few swing until the suitable size to insert into the calipers, then go ahead to swing.
- ✅【Premium Quality】Our brake caliper compressor uses high quality spreading plates with 1/8" thickness steel, high strength, not easy to deform. The lever handle has red cushion, skid resistance and feel good, will not hurt your hand while using. The bigger spreading plates with build-in small mag-nets and cylindrical pins, can install and unload quickly and easily from the compressor.
- ✅【Buy with confidence】 We offer 2 yr hassle free warranty, any quality issues in the meantime, you can ask for replacement. If they do not work for your car, you can use 90 days money-back policy.
