Upgrade calipers

[911mania]

I have a 1969 911 T. I would like to upgrade my front calipers and disc of a 964 or 944 Turbo. Do they fit with a 15" Hearts Fuchs? What do I need to fit the caliper? Do I have to change mastercylinder?
Thanks

Did this to my 69E. 964 Brakes. But I had 3.5" brake mounting from my Al calipers. If you have the 3" mounting for a stock T strut the you will need to buy struts with the 3.5" spacing. You will have to get a 964 rotor(24mm thick instead of 22mm) Also the mounting holes on the 964 brakes are 1/8" wider than even the 3.5" struts. So some adaptation is necessary.

Do not change the Master cylinder. It will work fine. A pic.

why do you want to downgrade your front calipers and disc to something heavy ??

what problem are you having?

964fronts are 28x298mm are you saying you used a 964 rotor?
964rears are 24x299mm

to the best of my knowledge neither will fit on a 911,

This pic shows what appears to be a Carrera 3.2 rotor, 24x 283mm, if you use 964 calipers front and rear the Carrera 3.2 rotors are what is usually used and both front and rear will be 2mm too thin, and 9mm rea r/17mm front too small in radius

if you have a 19mm non boosted m/c that is inadequate for all out stops, it works w/ long travel for low to moderate stops, but does not pump enough fluid for max dele stops, if you have a 20.6mm boosted m/c as used on SCs that is adequate but just barely, for a more confidence inspiring pedal use an ATE 23.8mm m/c, you will have to use a lot of leg but that goes hand in hand w/ a performance brake setup.

All in all you will have spent a relatively large amount of $ for a relatively small upgrade that marginally works

I run over 200HP and the PMB "T" Brembo upgrade gave me "S" size brakes. I went for the low suspension weight & minimum changes. Do you want Carrera power brakes for an EZ Pedal? My buddy has Carrera power brakes on his highly modified 70 and they are nice & easy to press. A 69 is still a pretty light car. Are you running a 3.6 or something? Just asking. Make yourself happy.
