TRYNKEEPUP 0 Posted August 18, 2008 Does any one know that a 20.8mm master cylinder will be ok with 306 gti6 brake setup, or will i need bigger m/c Share this post Link to post Share on other sites
James_R 3 Posted August 19, 2008 They'll still work, but most people switch to 23mm 406 non ABS MC's (4port jobs) when going up to these brakes to reduce pedal travel. this is the same size as the 306 gti6 MC the calipers came from. Share this post Link to post Share on other sites
dazEmad 0 Posted August 19, 2008 I find the gti6 brakes ok on the standard mc, theres a bit of pedal travel but i have got used to it. Share this post Link to post Share on other sites
