I removed them, purged and refilled with fresh fluid and capped them off.They are completely different, and the BR5 are a fine upgrade over the BR3:

BR3: Front 12.6" vented rotor, single piston caliper. Rear 12.6" Solid rotor (3/8" thick!!)

BR5: Front 13.6" vented rotor, dual piston caliper. Rear 12.6" vented rotorAttached Thumbnails
