After 2 years of being told there was nothing wrong, the dealers quality control person found my issue. It would cost $2500.00 to replace the brake activator.(part:$2,072, labor:$330. plus tax. Is this realistic?
There may be a Technical service Bulletin out for your model of Lexus in relation to your original concern leading up to this replacement. This price does sound high, although going to a certified Lexus dealership for repairs in traditionally high anyway. I do know that there have been concerns with a faint popping and clicking with brakes are applied if this was your original concern it does lead to a brake actuator replacement.
Hope this Helps!!
