Had a good look under the CT today… driver side, control arm bushing looks a tad perished. Bottom bushing under the brake disk look a tad moist at the top but couldn’t confirm (yet) if it’s worth replacing or causing the noise. checked the other side. Other side bushings look fine, same story with the one under the brake looks darker at the very top but nothing else looks bad.
seems to happen even when releasing the pedal so not entirely affected by moving weight of the car coming to a stop
Suspecting something on the brakes is either loose, worn, not sitting right or something like that.
Booked in with Toyota on Wednesday. I know what I’ll ask them to check… good news is, those parts I mentioned aren’t consumables so they’ll replace it. It’s also the same side / wheel that has caused trouble all along. Must have had some smack in the past… brake booster appears to be working fine when we checked today.
Next week, if they still don’t shed any light on it I’ll be checking the discs, pads, mounting bolts, pad support plates, slide pins, pad guide pins and the little anti squeal bits. Something will be a miss if it’s there.
Plan B.. get it serviced by Lexus on a wet day… and 30 days later book it in with a warranty issue and have it covered that way.
