To be honest I cant say if thats conclusive or described correct until I do the same with the other BX for comparison!
Over on Aussie frogs someone pointed a possible Rear HC sticking, well somehow I feel that more likely at this (easier to sort) considering all the work done on the Hydraulics of late and contaminated fluid spotted possibility of a sludge build up in the HC.
Why? because the back end dont sink for hours after the engine been turned off! Which now I think about it explains the spongey brakes on the other BX
I get what your meaning about Brake Failure last think I want is attendance from the local Fire Brigade of which I am a member
