Master Cylinders, etc.
All of the following master cylinders, suitable for brake or clutch operations, are constructed from lightweight aluminum alloys, and have 2.25" bolt centers for affixing to your vehicle.
Girling
Due to their rugged design, Girling master cylinders are used in many
forms of motorsports, including road racing, off-road and oval track applications.
Don't be fooled by cheap look-alike imitations, these are the real thing.
Both
models are available in the following bore sizes (marked on casting), 5/8" (.625"),
17.8mm (.70") and 3/4" (.75") which will suit most applications.
Order by bore size and either (left photo/drawing) remote or integral reservoir.

Girling Kits
Although we are not a big fan of "rebuilding" brake master
cylinders on a race vehicle, we have received inquires for such items.
Therefore below, are the part numbers for those seal kits

AP Racing
Just two of the popular AP series of master cylinders
CP2623 This master cylinder has become the most
popular of the AP master cylinders available. It is suitable
for brake and clutch applications, especially where space is restricted.
1.0"
stroke
CP6093 For most bore sizes, the longer available stroke versus the CP2623, makes it particularly suitable for some clutch installations.
Two of the most popular series of AP Racing light-weight master cylinders. Both are
supplied with a long threaded portion push rod to allow it to be cut to length
to suit.
IMPORTANT.. All AP Racing master cylinders are individually shimmed
during assembly to minimize free play, therefore push rods should not be changed
between individual master cylinders.
AP Racing has an easy way of identifying the bore sizes of their master cylinders.
When manufactured, each master cylinder has a color coded tie, wrapped
around the body of the cylinder which enables a quick visual identification
to be made.

Master Cylinder Reservoirs
Both of these plastic fluid reservoirs may be screwed directly to the master
cylinders, listed above. The AP Racing unit (part number 4709-) is available in
three different heights (3.5", 5.0",
7.0") and thus volumes. When attached directly to the master
cylinder, these reservoirs do not have the leakage problems of those other so
called, "racing" parts with their flimsy wire clips or snap rings for
attachment.
