Mkeenan 2 Report post Posted September 7, 2015 So I got the new brake lines and distribution block installed. When I tried to install the new mc it won't go all the way on without compressing. The old mc had some sort of spacer that looks like it doesn't belong. Here are some pictures of the fitment, spacer and push rod. I'm sure what is wrong, any ideas Quote Share this post Link to post Share on other sites
barnett468 418 Report post Posted September 7, 2015 . you need to use the metal spacer. set the clearance between the rod and the piston to .015" . . you need special tools to measure this. Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted September 8, 2015 Mine also had a white/yellowish plastic piece that matched up to the metal piece. Don't know if that because I have a Midland booster. I'll grab a pic. Quote Share this post Link to post Share on other sites

Brian Conway 264 Report post Posted September 8, 2015 You say " new brake lines and distribution block " do you have a new booster too ? The spacer and rod pictured are for use in a Midland style booster. The Bendix style booster does not use that equipment. Brian Quote Share this post Link to post Share on other sites
Mkeenan 2 Report post Posted September 8, 2015 The booster is from the previous owner. Judging from the pictures I have a midland setup and I am missing the whiteish plastic piece. When I bought the new master cylinder I just asked for a 1969 mustang mc, is there going to be a problem using the one I bought. They never asked me for a brake "name". The old mc and new one look identical. When I bought the car its brakes were non excistant, enough to get the car home, slowly. I started cheap first, I tired to bled the brake... Nothing no fluid. So I hooked up my vacuum pump, still nothing. When I tried to unhook the brake lines that's when I started to brake stuff. Long story short the brake lines were plugged at the distribution block, the mc was shot, the rear cylinders looked like they haven't seen fluid or worked in years and while trying to take stuff apart I pretty much rounded off or broke everything. Also where do you get this tool you speak of, I tried using my caliper but it doesn't fit to get the pushrod length. Quote Share this post Link to post Share on other sites
Brian Conway 264 Report post Posted September 8, 2015 I used a pencil. Erasure first into the MC to gauge that depth. Brian Quote Share this post Link to post Share on other sites
danno 128 Report post Posted September 8, 2015 Brakes are tough to figure out. I know. But if you get them done right, it can be a big accomplishment. Good luck. Quote Share this post Link to post Share on other sites
