Advise on car brake check in Berlin

Hi all, I’ve just had a brake check for my car recently since it has the brake pad warning light turning on, and got the quote of 900€ to replace the brake pad in the next appointment. I wonder if someone can help to take a look (quote is attached) and advise me if it’s a reasonable price (i’m pretty new in Germany in general). Also if this is not the proper subreddit to ask this type of question, please recommend me a proper one 🙂 Thank you in advance
