Yes, a vacuum leak can affect the air-fuel mixture in the engine, causing the engine to run inefficiently and potentially burn more fuel. This can result in increased fuel consumption and make you lose gas quicker.
On a vehicle equipped with power brakes the answer is yes. The P/B booster works on vacuum, so if the leak were severe enough it would make the brake pedal be very hard to push. Other than that, as vacuum leak would have no effect on braking.
check for a vacuum leak, i have seen some with loose carburetor bolts which make a vacuum leak. could be a bad hose, on the distibutor, maybe a bad power brake hose, could be a number of things
"Power Brakes" are actually "vacuum assisted brakes", meaning that a vacuum diaphragm is used to provide additional force against the brake pedal as you attempt to stop your vehicle. If the engine vacuum has decreased, through wear, timing issues or because of a vacuum leak, there will be considerably less of the vacuum assist available when you stop your vehicle. First, check for a vacuum leak, and make certain that you include the vacuum assist module. If there are no vacuum leaks, check the vacuum that the engine is creating; if that's not the problem then you may have a leaking or damaged master cylinder.
