hey
for the rear the fit kit is the same as the front: just smaller in size but the shim kit is a metal like bracket which clips into caliper after putting the brake pad in place and also stops the pads from moving. There is an actual pix of this on lexus~parts.com.
i had a worrisome clunk in front and this fixed it. and then when the front was quiet, i was able to hear some rattles in the rear and this fixed it also
hope this helps.

just an fyi... i installed the fit kit, and so far i havent heard any clunking... the first day driving around, after i would brake and take off it would hear it, but since then, ive heard nothing... maybe they need to break in? i got the shim kit to play it safe... i havent installed it yet, hopefully tomorrow..

I recently changed my pads, rotors and brakelines.
and now I get this "clunk" sound whenever i brake. it kind of sounds exactly like "clunk" like a rod or metal suddenly slipping out of its place.
It is noticeably coming from the front passenger wheel. It never used to be that way before the rotor, pad and ss line change.
I noticed that when I steadily knock on the wheel(tire) i can hear a kind of metal vibrating sound somewhere in the rotor/brake/caliper area. When i knock on the other wheel(driver side), it was firm and there was no sound coming from it.
My buddie is going to come and re-check the install on tuesday but i just wanted to see if anyone had any comments. I searched the forums but could not duplicate the situation through the search function.
I did read on the internet that sounds like that arise from a part of the caliper/ rotor/ brake not re-installed back tightly or correctly. could it be the caliper shifting or the pads not tight enough?
If i brake slowly and come to a steady stop wthout pushing the pedal to the limit, it does not occur.But when i brake like immediatley or to a complete stop it occcurs.
Besides that everything is perfect and i got the HUGE brake difference i was looking for from the rotors/pads/SS lines upgrade.
But this sound makes me think something is about to crack or break from how it sounds.
please advise guys
thanks

hey olddog, i just ran into this thread of yours and i couldnt be happier. My 16 LS is Doing the same thing and all the lexus techs is saying that is normal. I will take it to midas tomorrow to see if that is the case. It is bothering the crap out of me. Everytime i step on the brakes, either forward or reverse, the clunk is there so i hope this will take care of it

here is the exact reason why.
lexus techs relies on “codes” that may or may not appear in their techstream system so therefore they can not fix the issue. A midas tech or an outside tech uses his or her eyes, and hands to diagnose any issues that may be present, and that is exactly what happened today.
i took my ls to firestone and paid them to do an inspection to see what’s going on with my car. An hour after i got there, they found the reason for the clunking sound is the back control arms are bad as well as the bushings. They also found that my front shocks are leaking, and my radiator hose as well. Do keep in my that i had my car in a lexus dealership to diagnose the issues. I had an experience tech, 2 service managers that has been with lexus for more than 20 years told me that it is normal characteristic of an ls460.
Also, that “world class inspection” from lexus did not detect the radiator leak that has been going on.
See picture below for the diagnose at firestone
