My next door neighbor has been leasing Audi (A3 and A4). He had problems with both cars. He 's been waiting to get a BMW. His son just bought a Nissan G35.

Hello, Thanks VMF for replying. Since all of the rotors were under minimum thickness, I am replacing all. The rear ones come next week and I for sure will ask Checkers to machine them before I put them on. I checked what UCF3 said and I think all are tight (at least with my weakling arm )

Hi, I just took the rotors to Checkers for machining. The guys there said that they were sure that the rear rotors were the culprits. Beck-Arnley rear rotors will come next week and we will see. After the machining, I cleaned the rotors with brake cleaners, wiped them clear of metal particles. I torqued at 75. The test drive showed some improvement but the shakes are still there. Each rotor has 2 screw holes. The driver side one has the screws but the passenger side one does not have those screws (missing). All caliper parts are there. VH

It is raining in the Twin Cities now. I went to Checkers (where I got the rotors) and they would machine the rotors free of charge. I will do that when the sky makes up its mind :cries: More observations: 1. On the driver side (front), the rotor has 2 screws in the rotor. The passenger side does not. Does it matter? 2. When the brake pedal shudders, the gear shift handle rod also shudders (50% of the time). Maybe something else here?

Thanks to all of you who helped. My pedal shudders when I brake. The shudder frequency is half a second apart (counting 1001 as 1 second). The shudder decreases as the car slows down to a stop.

Thanks for your reply VMF! I did not brake hard. As a matter of fact, I am trying to 'break' (pardon the pun !) the new brake rotors and pads ! Do I have to turn the NEW rotors even ?

Hi VBDenny, Thanks for your reply. Yes, there are 2 shims (each facing the other) on each brake pad. I even used anti-squeal brake compound (orange colored) between them and the pad. There are 2 wish-bone-like springs (facing end to end) on each pad as well and they are there. I think that the shudders must come from some other components down there ? Thanks again VH

Hi, I just replaced both front rotors and new brake pads. I checked and greased the caliper pins. Yet, when I brake, there still is shuddering on the pedal. Why? I also used high temp paint (grey to match the car) on the calipers (my son does not want the calipers to be noticeable Thanks for any tips on the shudders.

Hi, Last few days, when we start up the 91 LS400 (135), there is a thick smell of gas. Last month, I cleaned the Throttle Body. Any thought? Thanks VH

My back is pretty ugly :whistles:

That's the site of the manufacturer of rotors shown by UCF3?

Quote from VMF: ' 99ls, your front rotors are the same size as those supra rotors and 95 up all LS has dual piston front calipers, so you dont really have to increase the diameter of your rotors. all you need is some slotted/drilled upgrade. that kit UCF3 showed is for gen I only and will not fit 95 and up models' I checked the Wilwood site and thought that 91 LS400 did not get a mention????

Hi, Thanks for the posting. Could you help with the following: 1. Pictures if possible 2. Would you say ' A person who can change brakes pads can do this' ?

Hi, Sorry to see about your broken belt. The brake sound happened to me once. I don't think it was serious because it went away. Anyway, do a search on this forum because somebody provided me with a good explanation. Don't worry. It is a good car.

You can email them with details of your car by clicking their address at top right hand corner of their web page

Hi, The CAR-X guy who checked my son 91 LS400 brake rotors yesterday used a device that he attached to the air gun. He said that the device would torque the lugs at 80. He showed me that the lug stopped spinning once the torque was reached.

Hi, Anybody knows these sites? http://www.performancerotors.com/index.php...26c15b5ecf163a8 or http://www.importrp.com/catalog.php?subcat...rs&subcat_id=11

Thanks Bob. I called the company (they are in Canada). Pretty helpful. I am including them on my list of options. Any thoughts on Rotora rotor? Rotora's slotted performance rotors are double disc ground and milled balance to ensure all OE specifications and provide maximum stopping power. Features: Dissipate heat away from the rotors which reduces warping "E-coated" (black) to prevent corrosion and increase life Mill balanced (within 150 g/cm) to prevent vibration Fits Rotora Lexus Ls 400 1991, 1992.

Thanks VH 03 X5 4.4 99 ML320 91 LS400 92 Prelude 91 Galant

Just put on ceramic pads on rear 91 LS400. Will let you know after a while. See Gallery page 38 for 17" wheel (MBM 272 17" Kumho tires). Also currently shopping for slotted discs / painted calipers. 03 X5 4.4 99 ML320 91 LS400 92 Prelude 91 Galant

Sure you can change the pads (front and back) yourself. Very easy!!!! 1. Make sure that the wheels are chocked 2. Make sure that you tape the sockets (including the lug wrench) so that they don't scratch your wheels 3. The Lexus tool kit is excellent. You won't be disappointed using them 4. Make sure that your new pads come with shims (thin metal plates that are attached to the pads on the outside surface facing the road); use the anti-squeal glue to apply them 5. Make sure that you put back the 2 springs 6. Watch the brake reservoir level (if full, you can siphon some off before the job) Great fun to do it and experience different brake experience afterwards!!!

What speed were you doing? Depending on the insurance company: some cut the check to you, some to the repair shop. By the description, it may not be that bad. If so, should keep the car and repair to as good as new B) Good luck !

Sorry for the late reply. I had a look at the subwoofer cover on the back shelf. There seem to be a couple of plastic clips (one on each side towards the front). Pry off from the bottom will undo these clips.

I have never been a spammer (don't know how to do it). Why do I have 5 buttons instead of none?

I am sorry to see your reply. I am at work now. When I am home this evening, I will look into this and post.
