Hybrid 2016 Range Rover sport (autobiography ) EPB )

As of 14th sept no VSI available
Decelrometer test is not suitable for the EPB

To test the EPB
Engine off ,ignition on ,gearbox in neutral and all brakes off
With the rear wheels in the RBT ,start both rollers ,wait until the Amber EPB lamp illuminates .
Apply the EPB switch ,the switch will need to be applied few times till the efforts required are achieved .

The service brake can be tested the same way in the rollers engine off ,neutral selected .
I managed it without issue .however if your not happy or unsure testing the service brake in the rbt then carry out decelrometer test for the service brake ,but the EPB must be tested in the RBT
