The only relation between the brakes and the engine is vacuum. The brakes are vacuum power assisted. There is a brake booster that a vacuum hose goes from it to the intake manifold for engine vacuum. This vacuum gives power assistance when applying the brakes. If the vacuum is lost, then you have a rock hard brake pedal that takes 10 times as long to slow a vehicle down. That is the only relationship between the 2
The lubrication system is part of the engine itself. Without it, the moving engine parts inside the engine seize instantly. The oil is sucked up from the oil pan into the oil pump and then the pump circulates the oil thru small passages inside the engine block to the top end of the engine to lubricate the camshafts, valves and lifters. It also circulates it to the lower end to lubricate the bearings for the rods and crankshaft the turns
The cooling system circulates coolant thru passages in the engine block to cool the engine and prevent overheating. The waterpump is what circulates the coolant. The coolant then returns to the radiator where the engine fan blows air across it to cool the coolant, where it is then circulated thru the engine again.
