Upon leaving a grocery, I noticed break light, TRAC light, and another I've never seen lit up on instrument panel. Upon driving, I noticed the braking was sudden and touch. The brake fluid level is fine. What's up?

The amber TRAC OFF indicator will illuminate in order to alert the driver of an existing malfunction with the Enhanced Traction System (ETS). In this situation, enhanced traction will not be available. The ABS VI/ETS must be serviced in order to regain enhanced traction ability.
Probably a DTC-diagnostic trouble code stored in the EBCM - electronic brake control module !
For some reason these vehicles you need to bleed brakes several times, had same problem, so air hangs up in lines somewhere it apears. When you say brakes sticks, describe it better, locked up, or dragging on rotors?
More than likley its your VSC computer (VSC Trac, VSC Off, E brake and ABS brake lights all lit). This problem has been sited on other Sequoias that had the TSB brake caliper/rotor upgrade (recall) and that more than likely the VSC software or computer was not updated to meet the demands of the newly installed brake upgrade.
The ABS light is the Anti Lock Break system light. You may have a malfunction in there. . . Take it to your qualified brake specialist and have him check it out. completely. You may have a leak in the system, the traction control is controlled by the button on the console where you can turn it off and on. If you have tried the button, take it to a car repair service or a ugh dealership and get the problem diagnosed with advanced software. Do mess with your life, fix the brakes.
most times it is a sensor that is located around the brake area that needs replaced. Changing brakes will not fix abs light..ABS stands for anti brake system and has nothing to do with replacing brakes or rotors. It pervent your brakes from locking up and causing you to loose control of car. hope this helps and good luck and please rate this post....
I have a 2004 sequoia with the same problem. VSC TRAC, TRAC OFF & brake light comes on at the same time. Sometimes just the brake light and other times all three. Sometimes no lights. Does anyone have a fix?
CHECK ALTERNATOR OUTPUT.MAKE YOUR VOLTAGE OUT PUT IS 13.5 TO 14.5 VOLTS.IF NOT ALTERNATOR BAD IF ALTERNATOR GOOD THE DEALERSHIP HAS TO HOOK CAR TO DIAGNOSTIC TO CHECK THE ENGINE PCM CONTROLS AND ABS BRAKES AND TRAC.SYSTEM.REASON I SAID ALTERNATOR BECAUSE I SEEN ALTERNATOR GO BAD UNTIL IT OUTPUT WAS LOW CAUSING CHECK ENGINE LIGHT AND ABS LIGHT TO COME ON.
Usually when th fluid level low light comes on, it is because the fluid is ging to the front calipers to fill the pistons that push the brake pads against the rotors. This is because the pads are worn down and probably need replacing.
As for the 3 beeps, it is not related to the brakes.
if it is 5 beeps, it is the air bag or pretensioner.
When the ignition is cycled (turned off and then on), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash the two-digit LFC. The air bag indicator will flash the LFC five times, then it will remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the data link connector (DLC), using the scan tool. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the GEM to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.
Hello, let's see what we can do.
To answer your question, yes they are related. Either your ABS system is malfunctioning, you need to replace your brake pads or the vacuum booster is leaking.
Do you hear a hissing sound under the hood? If so it might be the vacuum booster. Does the engine run rough when you apply the brakes? That can indicate the same problem. Let me know what you find.
