jamesStag Posted October 31, 2014 Report Share Posted October 31, 2014 Hi John & Peter, Thanks both for your info.... Ah ha, is all clear now!! (sorry for delay, not been on forum to look recently at this) I'll get my car on the ramps soon and go checking, pretty sure they'll be missing as those stops don't look familiar at all.. Cheers, J.

rhine Posted October 31, 2014 Report Share Posted October 31, 2014 Have added a couple of photos here with wheels straight ahead and against the stop. This is a 1969 TR6 and looks like the 'device' on the bottom on the trunnion is eccentric - much like a cam Have indicated the cam and also where it engages the rest of the suspension on full lock.

yycdave Posted October 31, 2014 Report Share Posted October 31, 2014 This happened to me and in my case it was attributable to worn wheel bearings which allowed just enough "flex" on the hub/rotor to allow contact with inside of the caliper. Quote Link to post Share on other sites
Percy TR6 Posted January 13, 2015 Report Share Posted January 13, 2015 (edited) I have the same problem as described in this thread but having removed the lock stops it appears they offer no adjustment at all. I have seen replacement parts on Rimmers and Moss but they also look concentric. Is it possible to get eccentric collars anywhere? Steve ***IGNORE THIS POST **** I have answered my own question - Revington offer both a larger diameter stop and an eccentric one. http://www.revingtontr.com/shop/product_display.asp?mscssid=f89ewccugq068mduufv4rbpslbkt9t25&CarType=TR6&ProductID=156111%2D22 Steve Edited January 13, 2015 by Percy TR6 Quote Link to post Share on other sites
jemgee Posted January 13, 2015 Report Share Posted January 13, 2015 I bought a pair of oversize stops from Revington as this was a possible remedy when fitting Minilites. In the event I was able to get some 3 (or 6mm) spacers off fleabay and thus have them somewhere in the garage. When I get round to it I will fleabay them unless anyone here needs them Quote Link to post Share on other sites
TriumphV8 Posted January 13, 2015 Report Share Posted January 13, 2015 As I have wider wheels on both TR6 I needed modified stops. Took a look, made them in a lathe and if not sufficient made another one, just from ST50 steel. Easy and quickly done. Take original as a master and make new ones non excentric and little wider than the biggest excentric distance. Quote Link to post Share on other sites
peejay4A Posted January 13, 2015 Report Share Posted January 13, 2015 ...if you have a lathe that is. Quote Link to post Share on other sites
TriumphV8 Posted January 14, 2015 Report Share Posted January 14, 2015 In Germany at the monthly round table from local TR-Register normally about 4 people are present to have a lathe. Reason might be that we often have bad quality spare parts or do not even get parts. So we started earlier to do our own manufacturing of such easy parts. Also meetings like Stone leigh can not be found in Germany. We have things like Veterama but that is mainly for German cars and bikes. Quote Link to post Share on other sites
dimliakos Posted June 7, 2021 Report Share Posted June 7, 2021 (edited) I finally found what is causing the the grooves on the inside of the front brake discs!!!!! If you hoist the tr6 the suspension drops and as you turn the front wheels left or right to see where the disc is binding is not shown. I used my hydraulic gearbox lifter to raise the front right suspension and it made it obvious strait away. The lower wisbone is held up to the trunion by a big bolt ¨pin¨. The whasher of the bid bolt as you turn the steering wheel to the left is ¨cutting¨ material from the disc like a lathe. Thats why you are getting a circumference like groove. Cure, grind up the whasher from the side of the disc and have in mind not to turn the steering wheel all the way. I was curious why in my case only the right side was having issues an I¨ve found out that from this side the 78 part ¨steering lock STOP¨ was missing an probably this is what was causing all the trouble.

Peter Cobbold Posted June 7, 2021 Report Share Posted June 7, 2021 Dimliakos, Welcome to the forum, and congratulations on reviving a 6 year old thread ! Yes, its the missing steering lock stop that is the problem. Peter Quote Link to post Share on other sites

Yes, its the missing steering lock stop that is the problem. Peter Can also be if the nut head isnt aligned flat in relation to the disc. Washers are not normally the problem if the correct one is fitted. Stuart. Edited June 8, 2021 by stuart Quote Link to post Share on other sites
Mike C Posted June 8, 2021 Report Share Posted June 8, 2021 Even the split pin can cut a groove in the disks if the stop is missing. Quote Link to post Share on other sites
John L Posted June 8, 2021 Report Share Posted June 8, 2021 (edited) Is there a particular direction the trunnion bolt should be fitted, I presume the bolt head should face forwards? Doesn't one of the wheels turn more on a full turn, is it the left one on a left full turn and the right on a full right turn? Ackerman steering?

Z320 Posted June 8, 2021 Report Share Posted June 8, 2021 Hi, the dust cover of the brake disc tells you the way the bolt has to be fitted: it has a small "window" for the head end of the bolt and a longer one for the threaded end with its nut. Quote Link to post Share on other sites

Don't you hate it when somebody brings facts to an interesting discussion? Thanks Marko. You're not only an amazing machinist, but you know "stuff" too Quote Link to post Share on other sites
