Brake Fluid Refill

[grizwizwg]

I was refilling my coolant recently (details in another post) and noticed that my brake fluid appears to be low (reservoir right next to coolant). That is, I cannot see any up to the max line...not sure if the brake fluid has a color of any kind like the coolant does (bright yellow). If not, it might be harder to see.

My question is, can we just add more brake fluid like we do coolant, wiper fluid, etc.? I've never done that before, but if we can, this is the product I'm tracking:

Brake fluid is clear. It is VERY hard to see. I would suggest not opening that reservoir. Dirt and moisture are important not enter the brake system.

Use a flashlight to shine through the reservoir and you'll be able to see the level.

It's probably fine. Brake fluid is only low if the brakes are very worn or there's a leak. Neither situation is very likely in a Lightning.

Thank you both for the info! I'll leave the cap on the reservoir and shine a flashlight on it to see where the level is at. Even if low, I'll leave it to the dealership

Also, check level with parking brake off.

Why does the parking brake need to be off??

The electric servo's push the caliper piston from the inboard side, of both rear calipers, I don't think it'll change the volume in the reservoir by much, but it should go down slightly when the EPB is active.
