I think I'm right saying a front wheel will only lock if the brake is squeezed very hard and fast ie: before the bike weight has been transferred fully forwards and therefore before grip has increased to compensate; or when the front suspension has compressed to its stops, or if too much brake is applied at slow speed when more often a stoppy occurs due to the transfer of weight forwards being too quick.
A rear brake should lock easily once a front brake is applied because all the weight of the rear is transferring to the front - no weight = no grip.
Hence why the best way for a biker to brake is rear first followed by front and release of rear then releasing front smoothly as the bike slows - weight moving backwards, grip decreasing, risk of lock-up increasing.
So, in summary the front brake should lock if squeezed to the Max immediately / if the forks bottom out/ or if too much brake is applied at slow speed. The rear brake will probably not lock on initial application but as a deceleration starts occurring and the weight moves forward the risk of locking hugely increases.
I will have a play on GpB later I'm sure there will be another factor such as the bike being used?
