Day! My car has been having problems with the brake force regulator for a short time. (Hoff that is the right name for the part, it does sit on the rear axle) It runs out. And quite strong. On the floor of my parking lot at home is already a wet spot that is almost a quarter as big as the car! Twice a week I have to refill brake fluid. Always have a one-litre refill canister with. Recently I tried to change the part. Cost material: € 92,– So up on the stage and look. The problem was that I could not open the screws, which hold the brake lines, which go into the brake force regulator. Quite stupid thing. I have already quite nudged the nuts by my attempts. After some attempts I stopped then. Did not want to break even more than it already is. A friend advised me to warm the screws. So make them really hot. That the screw nuts glow. With a welding device or something like that. He means that they can be solved more easily.
