Brake fluid?

Unless you have a leak, you should not be "low" in brake fluid...I smell upsell.
Did you check the reservoir yourself?
Not overly complicated, but will require two people for novice DIYers.

You can check the reservoir. When's the last time you had the fluid flushed? Depends on the vehicle but usually most service manuals recommend every 2 years or so.

Mirroring what has been said above - you should never need to top up brake fluid.

They make test strips for you too see what condition it's in, if it's bad, replace.
Don't go by arbitrary km or year 'rules'.

brake fluid is low because your pads are worn...... reservoir shouldnt be topped off to full when u have worn pads. the fluid will leak out when you push the caliper cylinder back to fit the new pads lol


or u might have a leak somewhere

Lots of possibilities here. They observed that:

1. Level is very close to the MIN line:
a. if brake pads are not close to needing replacement, it is a sign that there MAY be a leak that should be investigated (not just adding fluid)
b. if brake pads are near the end of their life, it is a reminder to be prepared to get quotes for replacement before you have to do it in a rush

2. Level is below the MIN line:
a. if brake pads are not close to needing replacement, most likely you have a leak that needs to be investigated right away
b. if brake pads are near the end of their life, get quotes for a complete brake job including check for leaks and full replacement of fluid

Is the shop suggesting getting one of the services they offer? If so, what is it?

Like above said, a good reason is the pads getting worn out. That is normal. When did you last replaced your pads?

The worst thing they will do is to charge you money and top up the fluid on worn pads, which would be a complete waste of money.

Oil change places are the worst places for other services because their whole business model is based on upsell.

Low oil change prices at near cost to draw you in then upsell once you are stuck inside.

This .
The fluid goes low as pads wear.
