Engineering Explained hits the road to find out which method – neutral or engine braking – is more fuel efficient. This causes the brake pad to ride the edge of the rotor causing rational braking noise so you may hear grinding noise when braking but pads are fine. Transmission downshifts should be the first line of defense, increasing the engine's speed to provide the necessary engine braking. By shifting to a lower gear in a manual transmission , or selecting the "low" mode on an automatic transmission , engine braking reduces the need to repeatedly apply the foot brake , lowering the risk of the brakes overheating.
