Can engine braking damage engine?
First of all, to dispel the myth – engine braking does not harm your engine at all. Engines are designed to run at thousands of revs per minute for hours at a time. Changing down, whilst may be a bit jerky at times, doesn’t inflict any damage. It’s also good for the engine because it was designed to be driven that way.

Slow and gradual is better unless you’re on a racetrack or need to panic stop. Heat dissipates more easily when you’re making a little friction over a long time, and your brake pads and rotors will last way longer.
Should I change my oil after the first 1000 miles?

How long should you leave break in oil in a new engine?
