supraspeed Posted September 10, 2008 Share Posted September 10, 2008 Ok, ive put new set of wheels on my car... but there is only about a 3/4mm gap between the spokes and the calipers- i think the brakes are upgraded UK spec ones as they are massive but until i get them looked at i'm not sure. anyway i was talking to the guy whos sorting out my bodywork and he said it might be worth skimming the discs a few mm. just want to know if there would be any problems with this tightness/distance as i dont want to damage anything and is it worth skimming them?

AndyT Posted September 10, 2008 Share Posted September 10, 2008 You'd need smaller feeler gauges to check the clearance on Ivans car. Bondj700 lovely Lexus wheels are pretty darn close too. Link to comment Share on other sites More sharing options...
jim_supra Posted September 10, 2008 Share Posted September 10, 2008 Skimming the disc will achieve nothing. The caliper is fixed to the hub not the disc so no matter what you do to the disc the caliper will remain in the same place. Link to comment Share on other sites More sharing options...
supraspeed Posted September 10, 2008 Author Share Posted September 10, 2008 How would skimming the discs help? well, i'm not mechnically minded but i assumed thinner discs = calipers were pressed/adjusted closer in? i dont know why he suggested it otherwise lol?

Rob Dublin Posted September 10, 2008 Share Posted September 10, 2008 Did you/he mean skim the top of the caliper? Wouldn't have thought this would be a great idea as it would reduce its strength. Link to comment Share on other sites More sharing options...
ShamelessTT Posted September 10, 2008 Share Posted September 10, 2008 (edited) Surely if there missing , there missing..........they shouldnt move now should they..........else something has gone t*ts up anyway. Get some thin spacers made tho if ur worried.... Edited September 10, 2008 by ShamelessTT (see edit history) Link to comment Share on other sites More sharing options...
supraspeed Posted September 10, 2008 Author Share Posted September 10, 2008 i'm pretty sure he said the discs... its just i dont want anything to go wrong as ive spent a fu**ing fortune the last 6 months to get it ready and i'm getting back hopefully friday so if something happens i dont think i'l be best pleased to say the least lol Link to comment Share on other sites More sharing options...
markus99 Posted September 10, 2008 Share Posted September 10, 2008 How would skimming the discs help? my thoughts exactly, maybe try and offset the wheels very slightly. Link to comment Share on other sites More sharing options...

Calipers are assembled into one piece. It's the pistons that move. So if you skim discs the pistons would have to move out further to grip the caliper. That would mean more force trying to drag the piston out of the caliper and reduced efficiency. As long as your wheel turns and there is clearance you're gonna be ok.

ShamelessTT Posted September 10, 2008 Share Posted September 10, 2008 What about heat expansion? Fair point, only one way to find out then. Id get some thin spacers.....and not risk it Link to comment Share on other sites More sharing options...
supraspeed Posted September 10, 2008 Author Share Posted September 10, 2008 Well cheers guys thats a load off my mind. i was just wondering if the ground/road was bumpy or just sh*t then it could move it a bit thats all. i cant wait to drive the lean mean orange machine again Link to comment Share on other sites More sharing options...
Rob Dublin Posted September 10, 2008 Share Posted September 10, 2008 Maybe put a line of paint/tipex on the caliper & take it for a test drive. If the mark is still intact they don't rub. Link to comment Share on other sites More sharing options...
supratoy Posted September 10, 2008 Share Posted September 10, 2008 If its not touching nothing should really happen, I know alot of cars that have calipers that just miss the spokes and they are fine. You could shave a little off the calipers if you want, alot of americans do it because the ccw classics alot of the owners use need a 4mm spacer, but some dont use the spacer and shave the calipers. do a search on supraforums.com for ccw classic and the last few pages i think tell you about it.

AndyT Posted September 10, 2008 Share Posted September 10, 2008 Most heat is generated in the disc. If it was to transfer enough through the pads and into the piston enough to make a caliper expand 3/4 of a mm I think the seals would melt, fluid pour out, ignite and burn the tyre off causing steering difficulty first. Seriously though, I think it would take a lot more heat than that to make a lump the size of a caliper expand by that much. Link to comment Share on other sites More sharing options...
merckx Posted September 10, 2008 Share Posted September 10, 2008 but there is only about a 3/4mm gap between the spokes and the calipers- Is that 3 to 4mm or 0.75mm? Link to comment Share on other sites More sharing options...

If it was to transfer enough through the pads and into the piston enough to make a caliper expand 3/4 of a mm Glad i'm not the only one that found that funny. I reckon the caliper would melt before expanding anywhere near that much (0.75mm) Link to comment Share on other sites More sharing options...

Chris Wilson Posted September 10, 2008 Share Posted September 10, 2008 3 to 4 mm is OK IF the wheels are decent, cheap ones can deform in hard cornering, and the wheel bearings are spot on. You'll soon see if they are rubbing anyway. You could mill or turn a bit off the outside of the disc hub face, but I wouldn't, there's not a huge amount of meat there, and when you think about it properly, it'll bring the rim even CLOSER to the caliper Link to comment Share on other sites More sharing options...
ivan Posted September 10, 2008 Share Posted September 10, 2008 You'd need smaller feeler gauges to check the clearance on Ivans car. And that's with UK brakes and stock 17" wheels. Link to comment Share on other sites More sharing options...
Scott Posted September 10, 2008 Share Posted September 10, 2008 I reckon i have about a 0.010" gap between my spokes and my calipers. Not had any issues yet. Link to comment Share on other sites More sharing options...
