What model years is this TSIB for?

 

Grooved equals bad in my honest opinion...
The pads will now become groved as well and can cause problems down the line..

Usually when I slap new pads on, if I see the rotor has even a slight grove, it gets resurfaced (if able to, within spec)


So far for 06' & 07' ...

 

I'll throw the rotors away before I resurface them. I've NEVER had a resurfaced rotor that was worth a crap.

 

Same here. Biggest waste of money there is.

 

^ why is a resurfaced rotor crap?

 

I'm wondering about that myself considering I've had brakes done and rotors resurfaced on many vehicles including my IS and haven't had any problems.

 

no dount.
brake dust improvement is incredible.

change in stopping power - actually i prefer the new brakes they are not as grabby.

longer to stop - doesnt seem to be.

i am extreemly happy i did it.

 

Because most places won't grind them with a centerless grinder, they'll put them on a brake lathe which only peels and folds the metal over on itself to form an absurdly abrasive surface. As this wears off, it takes an inordinate amount of pad with it, and you end up with less service life than if you'd just stuffed in new pads and called it a day. Just to throw salt in the wound, every gram of metal removed is one gram less service life you would have retained had you not had the disc resurfaced.

 

I see.. do lexus dealerships usually use a centerless grinder? I also thought resurfacing the rotors makes the contact patch more consistant so that stopping distances are improved???

 

There is nothing you can do to a brake disc short of greasing/oiling it that will change stopping distance.

Lexus dealerships will use whatever the prevalent technology is. There is no mandate to use a centerless grinder. The service manual does say they should be ground, not turned, but I've seen lots of deviation from what the service manuals say at dealerships.

 

While I agree with Lobuxracer's opinion about it, my negativity about resurfacing goes beyond the waste aspect. My experience has always been that resurfaced rotors warp easier. My assumption is that this is due to the reduction of mass that causes the rotor's heat cycles to be more severe for each braking event. I also believe that a vented rotor would wind up being shaved more on one side than the other, so each side of the rotor would achieve different temperatures due to the difference in mass.

 

Even with what was said.I've never had any warp issue with a resurfaced rotor.
If I somehow do,I'll just get new rotors.I didn't pay for the my IS rotors to be resurfaced.
Most rotors will give you one resurface.Now if they're cut to deep,it's another story.

 

I had the TSIB done on my 350 at my 5k mile service, and have more than 1k miles on the new pads now. The new pads don't have as good initial bite and it requires more pedal effort it seems to stop. Overall, I would probably still choose the low dust pads if I had to choose again.

 

^^^^^^^^whut he said!

 

imma bout to do this tsib on my 20k service and was wondering if there were any fixes for the excessive squealing and reverse squealing? i think i read it somewhere before but cant find it even with the search...i was just wondering if any of you had that issue and if the tsib for the pads fixed this issue. i was thinking its because my brakes are so dirty and thats whats causing my brakes to squeal. but the squealing is really really irratating...pulling up next to a crap car that sounds fine when it breaks and i just spent x amount on my car to have it screeching as it stops is sorta embarassing lol
