Timing belt and brake fluid change at Alfa 147

Hello guys, our workshop gives on the estimate 3.5 hours for the timing belt (complete KIT) and 1 hour for the brake fluid change. Is this much too long. Is there only working with one arm and made in between by tea break? The brake fluid was always changed at my Ford in 25, 30 minutes, why should this take an entire hour at Alfa? Or is this simply based on a false construction?
