I am converting my '69 to power brakes using a kit from Master Power.
The "Power Brake pedal" they provided looks weird to me. It has a large delrin bushing with a 5/16 or so bolt through it.
My current pedal has a 5/8" or so shaft that runs through it an a cotter pin retainer.
What's the deal with the new pedal?

I ran into a similar confusion until a local Mustang guru showed me the way. The longer power-brake pedal doesn't mount in the same hole as the manual-brake pedal. There are holes above the heavily reinforced manual-brake/clutch holes. If your kit is like mine, you'll also have to open up a lower bolt hole and enlarge the hole where the master-cylinder rod comes through the firewall. I also had to drill out the threads where the studs on the booster pass through the firewall and pedal-hanger (don't drill out the one at 10 o'clock) ------------------

If it is like 67, the power brake pedal is longer (to reduce pedal effort) and gets its axle higher up in the dash/pedal braket than the standard brake. There is a 5/16" bolt through the braket to hold the axle in. You should find a corresponding hole in the dash/pedal braket.

What do you do with the stubby shaft sticking out where the Manual brake pedal was?

Don't remember having any issue with a stubby shaft. This may be where the comparaison stops. I'll check tonight when I get home and will let you know

Are you talking about the thick sleeves that the manual pedal shaft passed through? Oh yeah, is this a manual tranny or an auto?

I checked. There is nothing like you describe in my car.
If you had an automatic, when you removed the manual brake, you also removed the shaft (pedal axle). You do not need these parts anymore. All you have left is the shaft support pieces attached to the pedal support braket (1" piece of tube). You should not have any problem mounting your new PB pedal.If you have a stick, you will need to keep the shaft as it is part of the clutch pedal ! This shaft will not interfere with your PB pedal since the pedal is now atttached further back (and up)into the bracket I will try to send you a picture
Good luck

I have a manual car. It has a common shaft for both the clutch and brake pedal right now.
Does the shaft get shortened or anything?

I don't think so. The clutch pedal mounts to the left (from the drivers seat) of the pedal hanger, doesn't it? (My car is an auto, and I've only seen one manual trans set up close) If so, I think Pierre is correct, you can just hang the clutch pedal and be fine.------------------

Remove the pin one the right side, pull the clutch pedal off (from left side). As you do so, brake pedal will fall. Be also aware that the clutch pedal return spring will keep you from removing the clutch pedal !! You will need to take it (spring) off, I do not know any other way and this is a BIGGGGG pain (see one of the previous topic in archives)Install now the new brake pedal since you have more room. You can now slip the clutch pedal back in (make sure to use new bushings) and stick the pin back on the right side. Re-installing the spring will be a real challenge. I personally used 40 washers that I stuck between the spirals of the spring to make it longer. Keep in mind that a 69 might be different
