The brakes on the Premier have always been effective, and the airplane can land and stop in 3,170 feet of runway after crossing the threshold at 50 feet at maximum landing weight. But, the brakes were hard to use at lower speeds, particularly during taxi. The reason is the brake pedals were linked to the hydraulic valves by cables and pushrods, and it was impossible to remove every bit of play from the system. When a pilot moved his feet on the brakes there was a slight lag before the brake valve sent high pressure hydraulic fluid to the brake pads, and that caused a lot of jerking around. The Premier IA has its pedals linked directly to the hydraulic valves and that, combined with a new anti-skid system, has totally solved the problem. Now it's easy to taxi the IA at any speed, and landing rollout is a smooth, straight-ahead affair.
