wrightbr Posted April 6, 2003 Share Posted April 6, 2003 I have a UK TT Auto and have a small vibration under heavy braking over 60+mph. I had new front discs and pads two years ago (around 6000 miles ago) and new pads and discs on the rear (under 1000 miles ago). Seems to be comming from the fronts but steering wheel is not vibrating heavily, but I can hear a vibration ( if that makes sense!)? There is plenty of wear left on the front pads and I cannot believe that I have warped a fairly new set of front discs with loads of wear left in them? Can anybody suggest what else this could be? Apologies if this has been covered before somewhere:innocent: Cheers Brad Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted April 6, 2003 Share Posted April 6, 2003 This will 99% be due to warped front disks, or unbalanced alloys.... If you go over a few pot holes this can throw out the ballance of the wheels, if you dont think its this (i probaly doubt) Its your front break disks, If you use them allot which u prob do,, (we all do) then they have become over heated and warped, a slight warp will make the steering wheel shake a bit a high speeds and it also wears down your pads unevenly.

wrightbr Posted April 7, 2003 Author Share Posted April 7, 2003 Thanks for the info. hmm have monster speed ramps on my estate so wonder if hitting these hard could have put the wheels out of balance? Was hoping that it was the pads or something (glazed pads?) as I can hear it more than I can feel it ? Will have to look to replace the discs soon then. Standard toyota or is there anything better out there (cross drilled?) for roughly the same price? Cheers Brad Quote Link to comment Share on other sites More sharing options...
TRD3000GT Posted April 7, 2003 Share Posted April 7, 2003 These are good ones but I dont know a UK supplier... http://www.suprastore.com/powslotfronr.html about £100 Quote Link to comment Share on other sites More sharing options...
Brian Jackett Posted April 7, 2003 Share Posted April 7, 2003 Speak to Chris Wilson, He supplied discs all round for my J-spec for about £70 each, I think. And got them delivered in post You must also get new pads as well Quote Link to comment Share on other sites More sharing options...
B3any Posted April 7, 2003 Share Posted April 7, 2003 Mine were doing the same, i got the discs re-skimmed for £30 a disc and it stopped, worth considering Quote Link to comment Share on other sites More sharing options...
wrightbr Posted April 7, 2003 Author Share Posted April 7, 2003 Just spoken to someone who said that Porsche now have a machine that can re-skim discs whilst they are still on the car (machine fixes to the hub apparently?). Does anybody know if Toyota dealerships have anything similar (or anyone in the Kent area?)? Also been advised that I would be better off having my discs skimmed rather than buying new discs as they are fairly new and now will be hardened up as they have been used.

Guest Martin F Posted April 8, 2003 Share Posted April 8, 2003 Get somebody to check the runout on the disks and hub area first before replacing or having skimmed. Maybe they haven't been fitted correctly and it's only now that things are coming to light. If they never cleaned the seating area up before fitting the new disks on there could be all kinds of crap under them. Quote Link to comment Share on other sites More sharing options...
Ian C Posted April 8, 2003 Share Posted April 8, 2003 I've just fitted new discs, well, about 1-2000 miles old, and they are thrumming a touch, juddering the wheel a bit, when braking from, hmm, moderate speeds They are so new that, if they are indeed warped, I want to try and get them skimmed, would a Toyota dealer be able to do this on a while-u-wait basis, do you know? Also, how much crap on the hub will cause this problem? I didn't clean the hubs but then it didn't exactly look like it needed cleaning, you know? And is there a rocket-science aspect to fitting new discs, as I just sort of plonked them back on. I'm willing to learn! Also just replaced my rear discs so I know it's not them at fault... -Ian Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted April 8, 2003 Share Posted April 8, 2003 Warped discs - You can warp them in a few miles of track use, so a few thousand on the road should be no problem. Just replace them. Quote Link to comment Share on other sites More sharing options...

wrightbr Posted April 9, 2003 Author Share Posted April 9, 2003 I will be getting mine skimmed as well. Will let you know when I have them done. Thanks for all the info. Cheers Brad Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted April 9, 2003 Share Posted April 9, 2003 Ian Do you mean £250 for skimming or replacing? New discs are about £75 each for UK spec and skimming should be about £35 each. I'm trying to figure out what you must have done to wreck discs so quickly. Mine are 5000 miles old with race pads and track day use, and show no problems at all.

Ian C Posted April 9, 2003 Share Posted April 9, 2003 I got mine off Chris Wilson for £250 inc postage and I think Chris's supplier isn't the cheapest in the world (no offense to Chris, I'm pretty sure he's not making a huge profit on them). I know now I can get them cheaper, if you could tell me where, John, I would appreciate it - I assume Toyota? I recall parking in the garage after an enthusiastic hoon and touching the front disc with my finger with a bit of spit on it, just to check, like, and the spit sizzled away instantly... So I think an inadequate cooldown procedure bent them -Ian Quote Link to comment Share on other sites More sharing options...
Need4Speed Posted April 9, 2003 Share Posted April 9, 2003 Ian UK discs (front) are £70.37 and £73.26 each (don't ask why they're not the same price). Part nos. are T43516-14030 and T43512-14200 respectively. Available at your local Toyota Dealer. Quote Link to comment Share on other sites More sharing options...
