Sounds like the dreaded speed sensor...

This could be as simple as some debris on the speed sensor so you'll need to inspect them. Or it could be a lot more complicated and that means a scan tool for error codes. Do you have access to scan tool for error codes?

I attached an exploded brake system diagram, which includes the speed sensors, in another thread this morning. Pages 5 and 6 of that PDF have the speed senors. Here's the thread https://www.clublexus.com/forums/sc-...-question.html

I put a big brake system on about 500 miles ago and nothing happened. If it is a speedo sensor, what am i looking at?
You guys rule

In terms of what?

Price. Won't happen again? Etc

Well that's going to be determined by any error codes that come up...e.g. damage sensor(s), dirty sensor, a bad cable or connector or any number of things.... there are about 20 error codes associated with VSC/ABS systems.
