Check brake system indicator intermittent

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?

    I woul suggest the following: Please go out and look at the master cylinder again. There is a "minimum" mark on the outer side of the cylinder. If the fluid is at or near this line, expect the light to come on. This is the low-fluid warning, measured by a sensor in the

    M-Cly. Note that this is a designed feature. As the brake pads wear, the brake fluid in the M-Cyl drops proportionally. Adding a bit of fluid may cure the issue, but, adding too much will be sprayed out from the cap when the brake pads are eventually replaced. Check the fluid & let me know wht you see. Thanks for selecting FixYa to resolve your issue.

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.

SOURCE: my brakes are spongy and i need to check brake fluid where is the brake fluid?

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.

Abs brake light

The Brakes may seem to work okey, but you have an
ABS Braking System light on- indicating a system fault,
just like any other check light you get

Do you not check for codes almost the same day any dash light
or check light comes on?

It will bite you some day-- if you ignore the reason they are there

ABS Light is on dashboard

Whenever 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 the problem(s)

My brake and abs lights keep coming on but they don't ever stay on for very long at a time and it usually just occurs when I hit a bump in the road is this something I should be concerned with?

yes, you have an intermittent problem with the system and if you are in a situation where you need to apply the brakes hard, the problem may cause failure of the anti-lock brake system, not a good thing. The system may have stored a code indicating where to start looking for the problem. Unfortunately you would need a scan tool to pull the codes.

Three intermittent warning lights

I would think a sensor is going bad , but ,without testing that is just a guess , just like the dealer tech , assuming it's a module or a fuse ! With the light's on checking for DTC'S - diagnostic trouble codes would be a real good first step . The dealer tech should have hooked up the Tech 2 scan tool an checked codes an look at sensor data parameters ....

Abs light is on

This generally means that you have a problem with your brake system. I would try opening the hood and checking the brake fluid level on your Avalon.

My brakes lose power system intermittently

It's quite possible you may need to check out your ABS system. Certain GM light trucks of that year, and a few in subsequent years had issues with the EBCM (electronic brake control module) These units are mounted on top of the ABS valve body, under the vehicle, on the left frame rail (all the brake tubing is attached). Sometimes the faulty unit would cause the electric ABS motor to continue running even after ignition shut down. Sometimes they would cause erratic ABS actuation.The other thing may be a faulty vacuum check valve at the brake booster. If that valve goes bad, your brake pedal will be really high and hard to depress. On some 1/2 ton GM trucks with vacuum assist power brakes, there is an electronic sensor that measure vacuum to the booster. In those instances typically a warning message will come across the drivers info center on the instrument panel. I hope this info can help.
