td_w 2 Posted May 29, 2020 hey there! As I am gonna change my servo and MC I need some nice new fluid suitable for track days. I think I need Dot 5.1 or Dot 5, but not sure which or either... any advice? Thx! Share this post Link to post Share on other sites
Tom Fenton 1,526 Posted May 29, 2020 Dot 5 is silicone based. It’s not really suitable for a 205 nor is it good at handling heat. Dot 4 or 5.1 will work. If serious about track work buy a good quality high temperature fluid. I use Motul. Share this post Link to post Share on other sites
td_w 2 Posted May 29, 2020 Perfect, thanks. This was also the one I thought wasn't super expensive or cheap and a good brand... Motul RBF660 Racing Brake Fluid Share this post Link to post Share on other sites
Tom Fenton 1,526 Posted May 29, 2020 Just be aware that it will need changing sooner than normal fluid would. Share this post Link to post Share on other sites

welshpug 1,626 Posted May 29, 2020 a litre would be more than enough really. Share this post Link to post Share on other sites
Tom Fenton 1,526 Posted May 30, 2020 Agreed a litre should be plenty. However if they haven’t been moved recently be very careful with the bleed nipples on the rear calipers, (if it has them) it’s very easy to break them off. Share this post Link to post Share on other sites
