Hello, I have a very special problem with my1989er 2410 Volga. After a while, when the temperature is higher, the brakes brake by themselves, the warmer the stronger. Also the pedal gets hard, I notice how the pedal path is shortened more and more. Once when stopping at noon did not get away at all. At the front the brakes become very hot, at the rear less. I have set the pedal path to the BKV manually, that has solved the brakes again. In cool condition and at fa half a year ago I replaced the front brake pads, all brake lines and the HBZ. A few days ago I renewed the BKV and re-aired it again. New brake fluid, the brakes are also top on the test bench. Because the brakes brake evenly and heat up, I close a blocked brake line or defective brake cylinders. ALB controller is the only not new part. I asked many people about it at the last car meeting, nobody had a concrete idea. Thanks for reading, having posted the same in the East-time forum, I would be happy for ideas and help
