Brake fluid problem

No.

Barring a leak, if his master cylinder reservoir reached low, then it means his brakes, pretty much all 4 of them, should be pretty well worn down. Topping off the reservoir just means he's procrastinating the maintenance of the biggest safety item on the car.

Sort the brakes, worry about the fluid level and/or fluid flush AFTER.

Taking that single comment out of context from my entire post, you would be correct. But read my entire comment, especially the first paragraph where I give the OP a clue without being too obvious as to what he should check and what he should do from there.

He never mentioned that he found any leaks. Surely if he does have a leak, he will quickly figure that out as his reservoir level will drop quickly again.

I did read the rest of your post, but your casual mention that piston don't have to move very far for the level to go down

Now that you've added that bit of fluid to make up for the difference in distance that the pistons have travelled, which really isn't very far, just a few millimeters,

And your casual comment that it's OK to top it up the when light turns on does not accurately communicate the significance of the brake warning light turning due to low fluid.

Every time I've had a car in my hands with a low fluid warning and no leaks, it's been because all the brake pads had basically no meat left. It's important to realise there is no reason for the master cylinder to hold more fluid above the warning level than what the brake calipers can hold at the minimum brake pad thickness, which is to say, if you've got evenly worn brakes and your brake warning is twitching on and off as the car moves, your concern is NOT topping off the reservoir, it's getting those brakes replaced ASAP.

Also, topping it off will usually make it overflow when you do replace the brakes.

So you’re mainly concerned with my casual, nonchalant way of giving out general advice.

That’s cool.

adding brake fluid is like a +3 months cheat code for vehicles!

*i've actually never ran through a full set of brake pads. always changed them(along with new fluid, rotors, and calipers if seized) on every used vehicle when i buy it, and then never touch them ever again. brz is the closest to eventually needing pads, but i'm not expecting them for at least another 40k miles..

I'm concerned about how you're casually instructing him that it's OK to blow off a red brake warning with a dab of fluid. That's not "general advice", general advice would be what best wax to use, your preference in suspension bushing durometer or even your favorite oil brand.

I'm not a doctor, just a mechanic, but when you're playing with people's brakes you're playing with their lives, and you're doing that casually sitting behind your keyboard going "yeah man, give her a little splash, shit's fine.". General advice would be it's never OK to top off brake fluid until you know the exact state of the brakes.

FINE!

I'll give him a full refund!

Just to set the record straight....
I bought new brake pads a couple months ago because the brakes squeaked once. I went to replace them. Simple job right? Not when you strip a lug stud! What a PITA!
I replaced the stud only to discover my brake pads were fine. My new pads are still in the box.
Funny related story.....
I heard my TOB squeak once. Bought a new TOB. Hasn't squeaked since. The new TOB is still in the box.
But as far as the original brake fluid problem goes....
I only had to add about two capfulls of fluid. It wasn't very much at all.

Oh
I forgot about the other squeak I had with the fan belt or whatever it's called now. It squeaked once.
It's still in the box.

I think I need help.
