Yes, ‘03 LX470, 253k KMs (157k miles) back in 2016.
Was the brake booster failure. Loud alarm, total brake failure, wife was driving alone when it happened and pulled over safely with both feet on brake pedal on a side street.
Toyota quoted $4700 (insane!) for the MC replacement as they wouldn’t sell just the booster.
Found a rebuilt booster on eBay for around $500 and a mechanic was able to install it without removing the MC (from watching YouTube videos for bolt locations). All in cost me around $700 CAD.
