ls460insc

I recenlty bought a 2008 ls460 with 41k on it. I am noticing that when I break I am getting virbration and steering wheel shaking. The tires look good. Should I need breaks or rotors or tires at 41k? There is no noise at all when this happens just shaking. I am former BMW 550 and 740 owner and even though they had TONS of issues they would stop on dime smooth as ice. Please help.

Sounds like warped rotors... this seems more likely than the calipers sticking

My 2008 has the same problem...i'm thinking warped rotors, but not sure. The previous owner had the rotors resurfaced last year, but I still get vibration on slow press of the brakes. If I press hard, then no vibration and the car stops on a dime.

That is exactly my issue. When I slammed on the breaks its fine. It's the slow stop.

It sounds like warped brake rotors to me as well. Someone may have improperly tightened the lug nuts when rotating tires. You could have the rotors resurfaced or replaced.

This is very typical of warped rotors. Surfacing a warped rotor is not always successful because the curing process of the rotor when it was being cast is probably the underling problem.
This is not really a big deal or exclusive to this car as it is typical on most every car especially when third party suppliers are involved.

Warped rotors seems to be the issue like the others said no big deal, have them cut/resurfaced for smoother stops, also check your pad wear while you are at it.

Sounds like warped rotors to me. I'm would say the cost of the Lexus rotors will be far cheaper than the cost of BMW rotors.

Either resurface or replace. Service tech can advise you .

I would not even bother taking it to Lexus for warped rotor replacement. I would go to Napa auto parts and purchase their ultra premium rotors which have been cooled gradually during the curing process and then have any competent brake person replace the rotors.

This is such easy work that doesn't require a Lexus technician.

warped rotors . Easy fix. Probably less then 200 bucks. It happens but can be fixed easily.

Rotors do not warp easily! What you are experiencing is excessive run out due to either improper torquing of the tires or the rotor isn't true to the hub. Another possibility is the pad material has deposited onto the rotor surface.

sounds like a stretch. Like we say in the medical field, if you hear hoof steps think horses not zebras. You are talking zebras right now. I would bet a lot of cash its the rotors. Any other explanation,imho, is a stretch

It is the rotors, but they are not warped is what I am trying to explain. And, it's not a stretch, it's the actual cause of the pulsation. Many people don't understand what a warped rotor truly is, as is evident by this thread and most of the responses.

if its "either improper torquing of the tires or the rotor isn't true to the hub." then why does it stop when they resurface rotors. why wouldnt they just retorque the tires and replace the rotor to be true to the hub.

hypervish

Sometimes just re-torquing the wheel and cleaning the hub does the trick.

The reason why resurfacing is required in most scenarios is to remove the excessive runout caused by pad deposits.
