ealry car brake setup, rear calipers

[Shuie]

Im going to run 87 Carerra calipers and slotted rotors in the front with a 19mm master cylinder on my '73T.

My rear calipers are stuck and rusted. Im not sure yet if they are rebuildable or not, but Im not counting on it. Id like to upgrade the rears if possible while keeping my 19mm master cylinder and the Carerra caliper/rotor setup.

What are my options for rear calipers that allow me to keep the 19mm master cylinder?

Thanks ahead of time.

Thanks Alf

From my page that Alf referenced;

The first 4 options can be used with either a 19 mm non-boosted mc or a 20.6 mm boosted m/c which are the stock ones. The 5th and suusequent options need a 23mm turbo boosted m/c or a 23mm ATE #3.2123-1003.3 non-boosted m/c
There are 5 upgrade paths when 15" rims are used. Listed in increasing order of thermal and mechanical potency;

1) Since most of the braking load is handled at the front. Leave the rear SC M caliper/rotors alone and replace the front SC A caliper/rotors with the wide A(~76cm2/caliper pad area) from an '84-89 Carrera the rotor is 4 mm thicker than the SC rotor but retains the same diameter, the pad area is the same as the SC A as are the piston sizes. The hydraulic bias remains stock and a small increase in thermal reserve is realized. Slotted versions will be a nice upgrade for these rotors. When used with aggressive pads, cooling ducts and high temp fluid minor over heating problems can often be eliminated w/ this set up.
