In spring, the 9-3 I Aero was released better brakes upgraded. The system from the 9-5 OG Aero, which can also be found in the Viggen, has been serving well since then. The brakes are (almost) no longer an issue. The 9-3 was meanwhile in Hamburg, Kiel, Bamberg and otherwise on a long distance on the way.
He does a great job, amazing for a car that will soon be 20 years old. Summer heat of more than 30 degrees leaves it as unimpressed as heavy rain on Hessian highways. With his comparatively narrow 215er Michelins he pulls his tracks even in aquaplaning, even without ESP. His brakes are a win, they delay even in the wet sustainable. Only one point bothers.
After the first euphoria subsided, I noticed the difference to a modern car. A pedal travel when braking that was a little too long and a bit too indifferent. And with it the uneasy feeling of giving away one or two seconds when stepping on the brakes. So what to do?
One possibility would be to upgrade with additional Viggen hardware. The brake booster in the Viggen is designed differently, it would certainly bring a further improvement. Alternatively, I can think of the option of switching to steel braided brake lines. They are the classic when it comes to improving the pressure point when braking. Their stainless steel mesh prevents the Teflon brake hoses from expanding and their service life is almost unlimited. In addition, the closed system means that the brake fluid absorbs less water, which is another plus point.
In addition, there would be the cost issue. The remodeling of the Viggen hardware is more complicated than the transition to new brake lines. Kiel and Frankfurt, which I ask for advice, unanimously advise me to Stahlflex solution as the next step. With which the conversion is decided.
Last week in Fechenheim. Saab Service Frankfurt has had the new brake lines made, the Aero comes to the workshop. In addition, still a small leak at the manifold flange must be eliminated, the Aero blowing since the trip to Kiel in the cold state clearly. The problem is solved quickly, the conversion is just as fast. On Thursday I can receive the Aero.
And how does he drive? The longer pedal path is gone, as if it had never existed. Was there something there? You forget quickly. The feel of the brake pedal is now as commonplace as any Audi or VW. All this costs, including labor and all materials, less than 400 €. Well spent money, which keeps the good, old Saab everyday and stress free.
