Picking up on your comment "If it is a warped disc you may notice a pulsing as the wheels rotate as you come to a stop on a smooth bit of road". This was the problem i had about 3 months ago and i also thought it was a warped disc at the front. I then proceeded to strip the N/Side front first and checked it for warping/runout with my trusty D.T.I. and found it was well within the 0.002" (two thousandth of an inch) tolerance zone quoted in the workshop manual. I also cleaned and checked the brake pads and calipers - all was in order. The only issue i had was a wear lip on the disc of approx 2 to 3mm on the outer and inner radiouses-this is caused by normal use ie:-the brake pads wearing the disc material as the brakes are applied. I checked how much meat was left on the disc and found again it was within tolerance so thinking that maybe the lip was the cause i carefully ground them down to the same level as the rest of the disc using my hand grinder (not recommended for peeps with a nervous disposition or shaky hands). I then carefully put everything back as the manual states in reverse order using Copper Grease in the appropriate areas. I then stripped and checked the O/Side front - this checked out exactly as per the N/Side so i carried out the same work as above and then went for a run - S!!!t the problem was still there. Next i proceeded to strip the O/Side rear - again eveything was in good order and as per Workshop Manual tolerances other than the wear lips on the disc which also received the same treatment as the fronts. Finally i stripped the N/Side rear and to my relief immediately saw the cause of my brake pulsing problem - i had a faulty disc - the disc forging had a hard bit of metal embedded/cast into it (approx 10mm wide x 30mm long). The pulsing was caused by the hard metal ie the softer metal either side of it had worn down by normal use of the brake pad leaving the hard bit protruding slightly. As the brakes were applied and the wheel was turning the hard bit intermittently came into contact with the brake pad which in turn caused the pulsing. I will upload my photos detailing this fault if someone can explain to me how to do it ?? To get the car back on the road and to see if i had sorted the problem i carefully ground the hard bit of metal down to slightly below the level of the softer part of the brake disc and put everything back and went for a run - the pulsing had gone and i have had no problems since - job done. Moral of the story is 1) don't assume its the fronts that are at fault 2) Always check everything carefully and 3) You don't have to spend hundreds of pounds sorting it out !!!!! I apologise for the lengthy nature of this post but maybe my experience will help others in the future.

No probs i'm glad the info was of use to you. PS: You can buy me a pint or two or more with the money you save if/when we ever meet up !!!

How often to people here clean their K&N filters ? I had a look on K&N's website, and here they talk about cleaning it every 50,000 miles, depending on driving conditions (which sounds like quite a long interval to me, I would have thought 20,000 or so might be more sensible ?) I personally think that you should clean and re-oil a K&N filter at least at the same time interval as you would a throw-away one which according to my Lexus Warranty & Care booklet is every 4 years/30,000 miles (whichever comes first) or sooner if you drive in dusty conditions/areas. However as i do all my own servicing and repairs i check, clean and re-oil my K&N every year/10,000 miles as it's amazing the amount of dust/debris that accumulates on it which must have a detrimental effect on engine breathing and in turn MPG. PS:-I drive mostly on single and dual carriageway "A" roads and keep to legal speed limits and my car consistently returns a true 30 to 33 MPG.

Rubbish mate, what do you do with your lexus air filter ? and whats the cost of lexus filter ? you can wash and use the K&N filter time and time again, so saving you money :D I totally agree with "GORD's" reply to "WYLIE COYOTE" as i have had a K&N filter on my IS 200se for the previous few months. One thing you also have to factor in on top of the cost of the K&N filter (code 33-2845 @ £30.99 + £7.50 p+p) is the cost of the Recharger Kit (code 99-5050) @ £12.99 delivered. This kit will enable you to clean and re-oil the filter approx Six times. In the long run, cost and environmentally wise it's a "No Brainer" decision. PS:- If you buy another Lexus you can fit it to the new one at no extra cost. PPS:- It's a good idea to keep the old throw-away filter for future use as it takes a day or two for the cleaned filter to dry before you can re-oil it. You don't want to run you're car without a filter on the two day's that you are waiting for the K&N one to dry out do you!

Hi Rob My e-mail addy is "jlgriffithsj@aol.com"

Hi Rob. Havent received my payment form as yet. Please forward to me A.S.A.P. so that i can forward the money to you. John

Thanks for the quick reply. I agree, it only takes seconds to remove the aerial and i'm still interested in buying one. Let me know the cost when youve done the deal.

Hi i,m No 4 on you're list wanting a cover. One thought that i've had is - does it take account of the roof mounted aerial which my IS 200 has ?
