when i had my 20k service, dealer told me that i had a brake leak, on the rear left tire i think it was. now I'm experiencing a "thump" and DEFINITELY it's NOT the clunk issue. every time I stop at a light, it make the "thump", like as if something fell off from under there. anyone know or had this problem yet?

 

The thumb can be from the RL brake where they fixed the leak. There might be moisture trap inside the drum assembly if they washed it with water. Or the pads are just moving when you step on the brakes.

I read that the clunk on the driveshaft has to do with the brake bias between the front and the back, fixing the leak could have change the bias. You should take it back to lexus to let them diagnose it.

yeah that's what i'm going to do, is it a long job? like they need to order parts for it?? Hate this, I can't use it very much becuz it was just in the shop last week!
