Try this, go to the inside of the vehicle and unhook the clutch rod. Then remove the safety switch to get access to the snap ring on the master cylinder and remove it. Be sure the tank is full of fluid. (Put a rag under the master inside the vehicle to catch fluid) Slowly pull the clutch rod out and the air will come out of the master. When the air is out carefully push the rod back into the master
