ok i currently have power drums, which i converted to power without changing the brake pedal (added aftermarket booster). I want to upgrade to disc in the front, however ive been reading that you have to have a different pedal when it comes to disc power. Im wondering if this is true and should i just go manual disc. This isnt my daily driver so i can put the extra leg into it if need be. If i kept the pedal the way it is and ran power disc what will happen? Its for a 68 mustang. thanks guys

 

Your good. Just add the disc brakes and you'll be fine. Don't forget the prop valve to rear brakes though.

You used to need to change the pedal when going to power before the new boosters came out.

 

so just have to get a disc/drum master cylinder & porp. valve... ?

 

Power drum and power disc used the same pedal. The pedal change was due to the difference in leverage for the factory booster, to prevent excess sensitivity. If your booster/pedal setup is working OK, leave it alone. Make sure you check the headspace on the disc master cylinder when you install it.

 

Someone added a booster to my car before I bought it but did not change the brake out. Overly sensitive and would lock up easy. Just recently started disk swap. Changing out MC, pedal (not that big of a deal), and putting porportioning valve in. See CSRP they have a good price on pedals - I've also seen them at mustang unlimited.

 

Holly-Molly, you talk about a "Grouping" of Disinformation, this takes the cake.

The 65 66 Pedal are the same. Disc Pedal Vs Drum pedal amounts to pad Size.

There are 4 Different pedals for the 67-70 Mustangs.

67 Small Pad with stop
67 Big pad with stop
68-69 Big Pad, No Stop
70 Pedal

Again, Standard Pedals, vs Auto Pedal have to be intered into to the equasion.

Manual brakes when set up correctly shouldn't require a bunch of leg effort. When done properly they should operate with about the same effort as a power system that uses a firmer pedal, and with very good feel and modulation characteristics.

 

When I went from power drum to power disc there was no pedal change

 

Good site on brake pedal differences. Hope it helps clear things up.
