Question about 2005 Toyota Corolla
My 'check brake system' indicator light comes on quite frequently and stays on for quite a while.
The brake fluid is fine. I was told recently the brakes are fine, though not perfect.
What else can I check?

You hava very common issue.
The brake fluid contracts when it is cold. The level may be "above the minimum", but being there allows the sensor to activate when it is cold, due to the contraction aspect of the brake fluid...
Add 1 ounce of brake fluid, and you problem will disappear.
A FixYa rating for my assistance would be greatly appreciated.

This is not just a matter of checking brake fluid level. Most likely you need to have
the brake fluid renewed in the entire brake system, something you should do biannually or so to prevent trouble.
If done in a professional way it will cure your problem, this process includes venting the brake lines for gas bubbles that are trapped inside causing the spongy feeling.
While it is not very difficult to do yourself I would still recommend you to have a professional do it for you, not worth the risks of potential brake failure if done wrong. It is normally an inexpensive procedure.

The ABS would have worked when the brake fluid dropped off. There is a maintenance schedule for checking brake pads/master cylinder kits. so if you have skipped this I recommend that it is important to have the brakes done up fully. Loss of fluid inthe system make the different wheels to lock seperately and the ABS sensors give command to the ECM to compensate-- the reason the rev went up.
So finally do not pour any fluid into because you have a faulty leak, maybe inthe wheel cylinder buckets. So have all the wheels checked before the fluids are replaced and bled to have your brakes back as new.

SOURCE: 2003 Corolla brake fluid leak.
If there is no visible leaking at the wheels around the braking assembly's, then the fluid will be leaking out he back of the blake master cylinder into the vacuum booster. The master cylinder is where you have been topping up the brake fluid and the booster is the big black thing the master cylinder is bolted to. You need to have this looked at by a mechanic for proper repair (unless you really trust someone),as brakes are something I think are important to a vehicles operation.
Just as a note, there is no need to buy a new master cylinder, as most brake places would have exchange units available.

this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS, TPMS and BCM faults and others) as long as the light is on. You
must now have the dealer hook up a special electronic diagnostic tool
and "scan" the system for the fault code that is stored for
