  1. I have the same problem and it drives me nuts ......I am going to start chasing it down on how to improve it. I will find a way to isolate it better.
  2. This the correct item you are talking about http://www.transmaticsc.com/index.htm
  3. Sorry.......what I mean by "studs" are the post top and bottom on actual brake pad shoe that are used to secure the pad assym. in place on the caliper housing. I concur ...the books call for a 04465-48060......and a 04465-48050's are on there now. Getting ready to call Lexus service manager and discuss the course of action they will take.
  4. If you have a spare moment, I would appreciate a copy, my mail can handle it no problem. :) sabre223@bellsouth.net COZ ........ "get over it dude" <_< Thank you very much for time and effort.
  5. Thanks for the link to get info.......lots of info however I could not find where it talked about the procedure for R&R of brake fluid. So the questions is what is the proper procedure for a complete replacement of brake fluid with ABS onboard ?? I jumped into the brakes this weekend and the first thing I found was the following: The front brake pads do not match what is in the manual by look, mine are 2 stud top and bottom and the manual shows 1 stud pads. Also these brakes pads do not sit snug and such in the caliper hosuing .....there is a 1/4 gap and that whats causing the clank when going from reverse to drive. I could not find anywhere on the net that showed the 99 RX300 having the 2 stud pads I have So I start calling this morning....keep in mind that the Lexus dealer where I bought it did the brake job 10 months ago, my bud at Toyota tells me the numbers on the back of the pad are worthless for tracking down info. I call my Lexus dealer and talk to the parts dude which I explain the situation and he looks up some numbers and this is what he had to say: Lexus number front pads #04465-48060 (1 stud) is what the 99 RX300 AWD calls for as its front pad. #04465-48050 (2 stud) like mine now .......... can work "OK" but is not the listed pad for the 99 RX300. He thinks thats were the clanking problems lies as well.........I took pictures and I need to post them. big frigging gap in there no wonder they are clanking....surprise they did not start clanking right away. Apperently the pads were held in place with some type of glue........perhaps thats the wrong word for it. Some type of pliable yet pretty hard substance that the brakes pads have come loose from thier shim plates and this allows the pads to move feely in the housing. It seems that the 00-02 models take different pads according to him. So at this point I dont know what to think.....been driving around 10 months with the wrong pads on Clanking noise is for the birds....should not be making such a noise.........never have had a vehicle that did and I owned a couple of Toyota and Nissan's and never have had such issues. It seems that it eveything is a mystery when it comes to Lexus parts .....just went through the same nut roll with the Transmission Pan gasket. Now I have read some artilces here that say the 1 stud pads dont fit ....the stud is too big ..... so now where does that leave us And of course still trying to track down the brake pulse Perhaps I should have started anew thread with this info.
  6. Thanks guys, yeah the pads are good.....brake job done at Lexus dealer where I bought it one year ago. However having looked over the records, brake fluid change does not up show up anywhere that I can see. Some of the history of this RX is missing ...meaning nothing on record. It acts like something intermittent,,,,,was suggested to remove the ABS fuse and see if its still there. Is it ok run that way ??? unsafe ?? or damaging ?? I was unsure about proceeding further with that. The reason I am wanting to replace the fliud is that the brakes are a little soft ......not really spongy ...yet not a distinct hard push. You know what I mean. I am all over that $ 10 download when I get home........is it the entire manual ??
  7. I am going to be doing some brake work this weekend, I am tired of the clunking nosie from the front brakes and this brake pulse thats happening as mentioned in my last topic. Time to jump in and found out what the heck is happening. I am going to replace the fliud first as I can not verify when or if its been changed. I want to do a good R&R of the brake fliud, will I need to do some special step to insure that the fliud in the ABS is replaced ?? Second..... what are your suggestions on this brake clunking noise.......the pads are moving within the caliper housing causing the clunk when going from reverse to drive. Use to be smooth as glass and no clunk, what has happened now I am very disappointed about the problems I am seeing with this RX after owning it a year now. Thanks for your time and effort :)
  8. Thanks all for your responses. I will check these issues and see if I get any further answers. I will post what I find.
  9. I have checked the entire system it, no leaks and no drop in fluid level. I going going to remove the front tires and look at things much closer. Perhaps the caliper is not moving freely as it should.
  10. Here is my situation, my brakess were working well and smotth til a couple of weeks ago when all of sudden I started feeling brake pulsing (not really throught the pedal) when coming to stops. Now it seems to vary sometimes, being worst at times than others and sometimes it feels smooth again. Question is do you think it is a cailper slide sticking issue or caliper bore sticking issue ?? Hope I have my thoughts right on the above. Thank for your time and effort.
  11. I have this same problem.........I also see it in the interior lights also. My wife said what heck is this going on ??? I had my alternator checked at the Lexus dealer some time back in reference to this issue and was reported good not much said about the flickering either. I have also read a few articles talking about this being a electrical flaw in the RX300 and no one can seem to track it down to what is causing it. Not sure you will like the answer about your alternator, its most likely good. It irritates me I am starting to see little things on this RX300 that are starting bug me. A few off my head: ** Gas mileage **Headlight and interior lights dimming issue **Fuel injection tapping noise.....very irritating, another its normal ** Of course worries on the Transmission ** Front Brakes making clanking issue....was told this is normal too man... I tell you I should have stayed with a the regular Toyota line. <_< never had any such problems with my other toyota's....kinda sad. I wish I had known about this site before I bought it, I would have definitly thought twice and most likely not gone this route. Kinda blowing steam at the moment sorry.
  12. Ar you saying that there is filter that now has a true filter in place of the screen ??
  13. Hey WWEST, would like to hear more about the modificationed above.
  14. Hey Tuned , thanks for the info, I will study them and see what my options are. "Whoever design the OEM pads should be fired." and for a few other designs :D
  15. Greetings all, done some searches and not coming up with a answer. Here is whats happening with my 99 RX300 and it just started........when I put it reverse and roll back a little bit and then put it in drive and come to my first stop regarless of short or long distance, I hear the pads clank against the caliper housing after that it does not do it again til I go into reverse again. I have had my RX now for 9 months and it just started. Lexus said it was normal <_< give me a break...... I am getting ready to remove the calipers and paint them do to them being rusty in appearance (any suggestions on that subject are welcome also) Any feedback is appreciated and thank you for your time :)
