My less than 7000 miles RX started making noise when I pushed the brake pedal. Evidently it sounded like the "LS brake squawk" according to service foreman. Current west coast port closings/delays is delaying my replacement part. I was just curious if anyone else had had this problem. Not sure if the actuator is same in all RXs.

I had the same squawk (seal barking) problem with my 2010 RX450h that the $2482.17 actuator replacement under extended warranty took care of . I think the brake actuator is only used on Toyota/Lexus hybrids. The same problem is common on the Prius too.

My 2015 450h with 7k miles has developed this problem. The dealer seems oblivious to any known issues and has bled the system with no fix. Has replacing the actuator fix the problem? Is there any information that I could pass on to my dealer, such as a tsb's?

I would suggest going to web site of Lexus of South Atlanta Parts and do your digging there. There may be other sources too. Your friendly Lexus dealer may be able to get you the same information and being local may charge you more.

Hey folks:
I've noticed a squeak coming from the brake pedal at some times when the pedal is depressed. Lubed the hinge pin for the pedal but no effect in noise. Any one encountered this before and know what it is? Also, is it a safety issue at all?

So, anyone know the actual culprit part? I see several (expensive) parts listed above. Which one is the actual issue and does the recommendation for the older RXes - to change the brake fluid- apply to the 2013 Rx450h?

Thanks, definitely in the cabin the source of the noise. SO much so that I thought it was the brake pedal hinge making the noise. Lubing that did nothing. But it's definitely very close to the driver's foot. Its a rubbery squawk. Rubber on metal noise of sort.

Any link with steering? The grommet may need lubing.

Happens mostly with quite firm braking, or cold weather (or some combination of the two). I can make it bark while at a standstill if I press down hard on the pedal. You mention squeeks and chirps too, mine is pure bark. And the noise is not in the cabin, I would describe the noise source as lower engine bay.
