….when changing to the winter tyres, my screwdriver noticed that the rear brake discs are very rusty at the edge. His recommendation: to brake strongly on the highway sometimes. Since I am a forward-looking driver, I use the brake really little, usually enough the distance to the frontman to avoid braking. However, he had an additional information: probably the brake force distribution on the front axle would be stronger at the Saab than at the BMW. That would explain the rust at the rear. m BMW would be less pronounced. Is that so?
