Hi everyone

It has happened the 2nd time today. While driving my break pedal suddenly become rock hard. I was driving downhill and had to use my hand break to stop. It lasted only for a few seconds, and then it was fine.
I think it was when my engine suddenly switched off. Does it has to do anything with hard break pedal?

It's brake, break is when you drop a plate.

If the engine is off, the brakes will go hard because the vacuum that the engine creates, that assists the brakes is gone. Not sure why your engine turned off suddenly but that will explain it. Turing your engine off when the car is moving is a bad idea, steering, brakes and potentially other things need the engine running to work properly.

Sorry I meant Brake
I was driving to petrol station and I was very low on petrol. I think engine switched (stalled) off either because I ran out of pertol or I was driving too slow for the selected gear? The brake pedal got hard. I tried to switch engine on a few times but wasn't able to, but once left it for a few seconds and tried again, it started. The brake was working normal then.

I would strongly agree with that as at age 18 I thought I'd try it out of curiosity. Steering lock went on whilst most other things going off as I was approaching a corner....

I did some stupid things. I am that person that if there is a big reb button marked "do not press" then I have an urge to press it.
