I have a 74 Grabber that when I purchased it came with no master cylinder or brake lines from the firewall forward. I have a prop. valve on the dr. side tower but all the lines are cut and I have no idea where to start to install them. Does anyone have a diagram of which lines go where or anything like that. As I said its a 74 Grabber, manual brakes, drums. I also have two lines coming from under the car one larger one and a smaller one. Any help is greatly appreciated. Thanks, John
Prob won't help a lot but here's pict of my '72 that is using orig drum lines, should be same as '74... Orig distribution block mounts just under hood hinge... http://i1358.photobucket.com/albums/q765/xxAMxx/Comet/cometmc_zpsa5cb4e31.jpg The large line from rear is the gas tank vent, the smaller is for brakes... http://i1358.photobucket.com/albums/q765/xxAMxx/Comet/brakelines_zps875964b3.jpg
BTW the original drum brake MC has equal size reservoirs, one pictured is for a '74 with disc brakes... I've converted to '69 Torino discs on mine... The fitting size is different between applications, I repl orig with fittings to match the '74 MC... Often replacement MC come with adapter fittings so can be used in a mutiple of applications...
I bought a new master cylinder for a drum brake one and have it all ready just had no idea which lines went where with your pictures and a diagram I found on a mustang website I have all the info I need. Tonight I start the new brake lines. Thanks again
'74s used the same master cylinder for both drum and disc brakes. It has a larger front reservoir than '70-'73 models, and one of the fittings (can't remember if it's front or rear) is different size. The hard lines on disc brake models that run to the front frame rails are also longer than the '70-'73 Mavericks, as the flex hoses are routed differently than on drum brakes. How do I know this? Because I am running a '74 master cylinder on my '73 with the front disc swap I did.
