Stopping...

From my remembering of driving the 77 it didn't stop so well by itself, So I have been doing some searching.
70s thunderbird calipers have bigger pistons 3something"
will the ones from a 80-96 fit any idea the size of them? What about the dual piston caliper ones from the D44 on the 250s?
Since im swapping over to efi I'm thinking I have to use a 86-96 master cylinder, on the 70s they say to upgrade to the F350 brake booster and master cylinder would this hold true with the 86-96 ones?
What about the rear with towing would the disk brake from the mid 70s lincolns be a good idea?

Thanks
Curtis

I would follow the tech article that Dennis linked you to, it's written for a Bronco, but it's the same setup as a F150. Swapping to EFI has no effect on the master cylinder, so there is no need to use a newer one. Generally rear disks are better, but your drum setup is designed for hauling, the lincoln's discs aren't - I'd stick with the drums. Make sure the trailer has brakes that work good and you will be set.

Hey guys thanks for the link, and info. The efi set up requires a brake on off switch(BOO) that plugs into the master cylinder. I have only seen one without it my old 85 broncoII but that was a carbed computer unit so I will keep asking the efi guys and find out.

Thanks
Curtis

That brake switch that you are talking about gos on the pedal under the dash. Similar to the clutch switch. I could be wrong on this. My efi system needs nothing from the brakes.

Are you running a aftermarket efi set up? I am going to run a factory ford computer(A9L from a mustang). For the code scanning it is one of the thing you need to do brakes, power steering switch(if present) overdrive switch(if present).

Thanks
