pureboiracer 0 Report post Posted May 8, 2011 Hey guys, need to get another master cylinder for my race car. The one that came out was from a 7 series so i dont know what size one should go back in. The car is a pfl coupe with disc rear and no abs. As far as im aware there is about 3 or 4 different piston size setups. Anyone help? Cheers oli Quote Share this post Link to post Share on other sites

I have a couple in the garage which may be suitable - would do with a re-seal and hone though. Quote Share this post Link to post Share on other sites
