MARK Posted August 15, 2018 Report Share Posted August 15, 2018 (edited) A few years ago there was an article in the mag about improving handbrake efficiency by moving the fulcrum point closer to pivot point on the handbrake lever. I seem to remember Triumph recommended the mod for another model - Spitfire?? What location on the lever should the new hole be (closer to pivot point) be drilled? ( Diagram would help!) Is this an effective mod ? MARK Edited August 15, 2018 by MARK Quote Link to post Share on other sites
peter clarke Posted August 16, 2018 Report Share Posted August 16, 2018 You need to extend the length of the lever not shorten it by drilling closer to the pivot. You can buy extension pieces that use existing pin hole to mount and require no welding. Quote Link to post Share on other sites
Z320 Posted August 16, 2018 Report Share Posted August 16, 2018 Hi Mark, my handbrake works very well but I do not use leaver extensions. I reported at "Handbraaake" what I did, that works very well so I did not start my further brake project in 2018. https://www.tr-register.co.uk/forums/index.php?/topic/61888-handbraaake/ See post #17 on.

aardvark Posted August 16, 2018 Report Share Posted August 16, 2018 There is one available on eBay.co.uk today or you can diy by using the pattern shown in chapter 5 of the Williams book how to improve .... Cheers Dave Quote Link to post Share on other sites
tim hunt Posted August 16, 2018 Report Share Posted August 16, 2018 Msrk, the mod you mention is very effective, giving more mechanical advantage at expense of more lever movement. The hole centre for the compensator link should be drilled 7/16" closer to the fulcrum pin centre as in attached. Did this mod on my 4A 45 years ago and handbrake will hold on a 1 in 4 (with a good tug!. Tim Quote Link to post Share on other sites

TR Paul Posted August 16, 2018 Report Share Posted August 16, 2018 (edited) Hi Chaps, A couple of years ago, TRoy, My 1970 TR6 failed his MOT on handbrake adjustment (How unusual...). Whilst tending to this matter, I thought I'd drill the extra hole in the lever for the compensator link (after reading of this mod in TRaction.). Imagine my surprise, then, when I found that the (one & only) hole was already where I was going to drill it, and would've appeared to have left the factory like that! Perhaps it was a of dealer fitted improvement? Best wishes, Paul. Edited August 16, 2018 by TR Paul Quote Link to post Share on other sites
