Re: Dual rear brake calipers
You are right, i misformulated that part.
But the disadvantge of this system are more unsprung wait (perhaps) and locking up the rear wheel when it loses traction (wheel in the air).
When you brake hard and the rear wheel loses its traction then you will force the swingarm to maximum positon, then the caliper will stops the rear wheel from sprinning since it no longer force the swingarm towards the ground.
The rear wheel stops and the swingarm slightly goes in (negative springtravel).
When you no longer brake the rear wheel can spin again and the swingarm should be able to move again.
Could this be dangerous in the track, how about the forces you will force on the reaction bars,swingarm and frame?
