Roller & decel input readings bug? Feb 14, 2016 23:02:40 GMT 1

Had a BMW X6 with Xdrive for its first test on Friday. Our rollers spin opposite so it's safe to test 4WD's on it. No problems with the service brake but the electronic handbrake was very poor. Only about 100kg each with no lock. Thinking the lack of VSI meant I didn't have the correct test procedure for it, I opted to carry out a decel test.

Anyway, the handbrake worked perfectly fine so went to input the readings on comp 2. Chose roller for service brake and decel for parking. Put my readings in and noticed there was no option for telling the computer if any wheels locked or not. As it was a first test there was no weight given so it automatically failed the service brake efficiency. Lucky we had brake charts so I took the weight from them saving another decel test.

Anyone else experienced this?

Never caused a problem so far but does need to be sorted.

Poor excuse I know but was too busy at the time to report it and haven't remembered to do it so far this week. Only remembered to report on here because I took the pictures. I'll do it now.
