This query is based solely on my experience of driving 158s belonging to EMT, so I don't know if this is true across the entire fleet
When braking we are advised to start braking in step 2 the move it back to step 1 to get a full step 1 application. If we just go to step 1 all you get is a very gentle braking action rather than a proper application. This isn't unique to one unit, it seems true for all 158s.
Does anyone know why? Is it an intentional feature to help with maintaining high speed on falling gradients perhaps? Or is it just a quirk of the braking system?
TIA
