2004 Lexus ES330 Dash Brake Light...

My brother brought me his 2004 Lexus ES330 yesterday for a brake job. A shop had told him that it was going to be $740 to do both axles with pads and new rotors (they claimed the rotors were not machinable). So I tore it down and took the rotors in to be machined (they had plenty of material left on them). The parts store counter guy forgot to tell the brake lathe guy to machine them. So, 4 hours later, they had them finished and didn't charge me (I was quoted 1.5 hours when I dropped them off). He basically got a brake job for the cost of the new pads and some labor.

I got it all reassembled and took it for a test drive. As soon as I started backing out, the dash brake light came on and stayed on during the test drive. The brakes felt excellent - smooth and quiet - but the light stayed on. Once I got to my brother's house, I asked him about the light. He said it had been on for 2 to 3 weeks, but he forgot to mention it to me.

Now that I know I didn't do anything to cause it, does anyone know what would trigger that light on this particular vehicle?? The master cylinder is full, and the parking brake pedal is fully released. If anyone has any ideas, your input will be greatly appreciated. Thanks in advance.

P.S. The ABS light goes off and stays off - this is just the brake light that is coming on.

Check the float in the master cylinder as the tend to stick on these cars. What may look like a full master cylinder may indeed be lower than expected. Try adding some additional fluid without exceeding the maximum fluid level. Did this vehicle have pad sensors on it? If so you may end up replacing one or more pad sensors to resolve this issue.

No pad sensors on this vehicle. The fluid is full (new pads, calipers compressed). Some online research shows some people have just tapped on the reservoir near the level sensor to free it up, so I may try that.

You have a brake light out. Easy fix.

The dash brake light is not used for burned out bulbs - it only pertains to the parking brake and the master cylinder level sensor (according to the owners manual). There is a different dash light for bulbs that need to be replaced.

So this one is the red indicator, not the yellow one? Only thing that turns that on is the float in the master cylinder or the parking brake switch.
