I notice that on the B2 series now being delivered you are using AMR2 brake lining. Would you please let me know if this is the same material as you are using on the Bentley, and if so whether we are likely to suffer from the same defects as we are suffering with the Bentley brakes, i.e. serious inefficiency when the brake shoes are wet, brake shudders and brake squeaks ?
