If you are a diy guy the axle can be had for less than $100, however the labor is the challenge. I have replaced my left drive axle. (not for ABS) And it does come with the sensor ring.

i had a tooth in the sensor ring break off...my symptoms were similar, abs engaging at slow speeds when braking. the sensors were ok, the ring was not... i remember the day it broke.. i drove it several weeks that way. i was told you can disengage the abs if you want and drive it without. i decided that the abs was desirable and opted to repair the problem.

and yep had to replace the whole axle on the right rear. had the dealer do it ( i am a tool & die maker but not a car repairperson, lol) it cost about $900. my rx300 is a 2003.

Nothing to do with brakes directly, but at the full turn ... lock position ... your steering pump goes somewhat berserk as it develops full pressure and relief valves get into action. This may influence the engine load and also the vacuum.

A similar condition happens when the a/c compressor kicks in and out and you feel it in the brake pedal.

I'm not an expert on ABS but I find it hard to believe the ring would go bad, most things that work like this pick up via inductance a pulse from the teeth on the ring, that's how the ABS would calculate wheel motion... We will see I have an ABS light on right now on my RX...

They break way too easy on this car.

The only thing that I have noticed is that everyone with the broken ring complained about ABS activation (pulses in pedal). NEORX30GUY is just complaining about his ABS light being on. He may get lucky and have a different issue.

your rear sensors has rust build up causing the ABS sensor to be back out a little bit you need to remove the censor and clean the rust and reinstall and you will be good to go

Also the tone ring I rear being cracked will give you same problem

Well I haven't gotten to trouble shooting my ABS light, I appreciate all the input I just did the front brakes with new rotor's they were worn..Unrelated to ABS light...

Current setback..I got hit head-on & RX may be totaled...Not because of the damage but because of cost....If totaled I will probably buy it back from INS & do most of the repairs myself...

The RX is one rugged SUV...I fared much better than the Chevy Lumina that hit me...Just some bumper & minor (to me) headlight damage & transaxle cooling lines...

The Lumina had both airbags go off & the front end got creamed.. It was towed, I drove away!

There is the ring, sensor and wires. Any unintended action (mistake) can lead to ABS failure.

I hope no one got hurt during the accident.

Looks like i have similar problem but it not happens all the time i press the brake.
As I guess if ring is broken something like this may happens all the time, and if sensor is malfunction it maybe (i hope) more like sensor problem.

What do you think?

I will make appointment with dealer and will see what they say.
As always fear that mechanic will way it more to repair then it really needed.
relapse ring for 1000$ ++ and then you need to relapse sensors too.

Maybe I just meet bad mechanics like in PepBoys, but last time in local Lexus dealership with new manager it were soud like "pepboys" not Lexus.

Thank you for help.
