Air in hydraulic brakes? how to get out safely? (rammy.site)

Since we have a bike-repair sub here, so why not have a chat.

So I like my bike, when I am at home I ride the thing every day to work. So I got myself something nice a few years back. A nice Trekking-Bike with hydraulic brakes. Magura HS 11s. One slightly newer than the other.

Before I went to college for this semester I went to a shop to get the brakes fixed since the pads were pretty dead. Since I have to go to another city quite far away from college it stood there in the shed for a few months.

I went back home a few weeks ago I noticed that the brake handle is quite "loose" in the sense that I have to pull the handle for quite a bit before stuff happens. Pads do look quite good to me since they are basically new anyway.

Is it normal that brakes get air in that quickly?

Looking up online The service kit for these brakes with all the stuff needed is like 30€.

Looking at some videos it seems fairly easy of a job.

Sorry for the second one being german btw could not find any other for the specific model...

I am kinda unsure though I should try this myself since its the brakes we talk about... It seems quite easy and atleast manage changing tyres on bikes on my own. Would love to hear what you have to say.

When I started fixing bikes, I found that Park Tool has a lot of useful guides. (www.parktool.com)

Found a picture from when I replaced my rear sprocket a few months ago. As you can (hopefully) see, the old sprocket has lost a lot of material compared to the new one. The teeth aren't even symmetrical anymore! As you can guess, there was a lot of chain noise lol.
