The Saab 9-3 Aero of the first series brings, as a relatively lightweight and in connection with various Hirsch upgrades, sporty performance on the road. The Trollhättan Turbo is strong as a bear, only the brakes spoil the driving pleasure a bit.
They do not meet the requirements of the constantly growing volume of traffic and are in disproportion to the sporty pull-through values. My 9-3 Aero got for this reason slotted discs from the Orio range. They brought improvement, but could not completely convince.
New brakes in 9-5 Aero format
Another approach followed Reader Àkos. We have been in contact for a long time and he was looking for a solution for his 9-3 Aero. After lengthy research, he decided to upgrade to Aero brakes in the dimension of Saab 9-5, which have a diameter of 308 mm. In addition came new wishbones with Powerflex bushings, which should further improve the handling. The perforated and slotted EBC brakes and the matching pads came from the supplier Neobrotherswho was also able to give detailed advice on the topic.
An additional subframe and a Steering Rack Clamp were already installed. The upgrade of the brakes was at Saab specialists Michael Reichhold carried out. It must be noted that an 9-3 Aero with a new original wishbone already feels tight. With additional Powerflex bushings, the chassis gets harder by a few degrees, which also noticed Àkos.
And while the 9-3 Aero was now very tight and very sporty on the road, there was a feeling of dissatisfaction even after conversion and plenty of break-in time. The pressure point of the 308 mm brakes was spongy and imprecise, with braking performance per se noticeably better.
It began the search for possible causes. Bleeding the brakes and checking for leaks gave no indication. In the following step, the master cylinder was replaced to exclude it as the cause of the error. After extensive test drive no change was noticeable.
Precise braking performance with new ABS pressure pump
The next step was to change the ABS pressure pump, and the Saab immediately provided a precise pressure point when braking. This means that the braking feel corresponds to that of a well-tuned, modern car. The Saab 9-3 Aero Coupe is now sporty - with brakes that match its driving performance, preferably where there are beautiful mountain roads and high passes to be experienced. The picture of the article shows the Aero in Obergoms in the canton of Valais, near the Nufenen Pass with a height of 2.478 meters. Thanks to Àkos for his experience report!
