Yes, front brake can provide the majority of the braking force (up to 100% in some circumstances), so learn to use it well.


That said, don't just grab a handful of front brake; even without a suspension, weight transfer to the front wheel isn't instantaneous and if you get on the front brake too hard too quick you won't be a happy camper. Especially if you're on a less than ideal surface.


Also remember that your traction budget for each wheel is finite. If you're using some of it for turning you have less available for braking. Translation: you can brake harder (stop faster) going straight than if you're turning. Brake-swerve-brake.
