Using Hill Break

Using Hill Break
Has anyone ever had a problem while using the hill break? My 06 prius recenlty started reving up really fast for no apparent reason? I switch back into Drive, fearing a mechanical problem.
Any advise would be welcomed

the downside is? engines are not normally used to slow the car down, that's the brake's job or in the prius' case, the generator/electric braking and the brake pads themselves, therefore, in the long run this can lower your compression ratio thus reducing your engine efficiency and power output.
In other words, brakes are for stopping/slowing, engine is for moving
Just keep it in "D".
hope this makes sense,
if not , please dont hesitate to ask

over time, wear and tear gradually comes in, and for a person who consistently uses engine braking, this can speed that up.
Now, this may not apply to those who change their oil very regularly or religiously. But IMO it can happen. I know if you ask out there, you'll get a mixed crowd of people saying "it wont" and "it will". I was always taught that "it will". therefore, i like to keep it simple and use brakes for stopping and engine for moving. It's cheaper to replace brake pads than to overhaul an engine.

Prius B mode is a substitute for a traditional transmission lower gear, which would use regular engine compression to slow the vehicle.
B mode is not unsafe for the vehicle and is nothing like using engine compression for braking, as in a conventional vehicle, because the engine becomes nothing more than an air compressor.
In large road going semis, a Jacob's brake is an engine compression brake which suspends fuel to banks of cylinders, usually in pairs of 2, and uses the natural compression of the engine to help control speed and ease braking. It is very effective and it not damaging at all to the engine. Drivers of these vehicles uses these brakes on some very long downhill stretches for miles and miles.
In much the same way, the Prius suspends spark and fuel when in B mode and the ICE becomes nothing more than a sophisticated air compressor.
Please use B mode as you see fit with no concern over ICE longevity or wear and tear. B mode is there for you to use at your discretion.
