Very faint clicks at stop from brake actuator

Yes, probably means Apply, I just automatically thought it was Accumulator since its pressure source

Definitely make sense

Thanks

 

Update:

Actuator + Accumulator/Pump came in, installed and bled. Car brakes perfect.

• Pump comes on a lot less frequent and much shorter duration.
• No more clicks : faint one and the louder one felt on entire length of all 4 brake lines.

Will separately post all the challenges on install and cheap MVCI techstream setup.

 

Follow up with a graph of working actuator behavior after replacement.

Car in IG-ON mode (pressure power button 2x without foot on brake) Followed by foot on brake. Compare with failed actuator/accumulator in post #18



Note the following

• SLR is 0A entire time
• SLA does pulse every 3-4s gradually extending this time
• All other solenoids are stable.

Compared with failed part, very different picture (SLR going crazy)

Accumulator pump also runs much shorter period in all scenarios. Opening door (after a couple of hours) only produce 1-2s of pump run time. With the internally leaking actuator/accumulator combo, it would run 5s+ after opening the door.
