Hello, to my Belli, the brake pedal doesn’t come back when the engine is running? what can that be? are installed BKV and a 2 circuit brake system, brake force regulator block, discs front, I noticed only when I turned off the car and when I came back the brake lights were on, brake levers withdrawn by hand and then tried out, everything Roger, drove further and afterwards in the garage it was again! if I kick it so few times no problem, only occurs when the engine runs t, can it be due to the vacuum? Low pressure hose goes from the Bkv over to the suction spider where it is connected to the carburettor with one t piece! Maik
