Master Cylinders
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 had inquires over the years for such items. Therefore, below are the part numbers for those seal kits
Girling 5/8" Bore kit part# 2E0789
Girling .70" Bore kit part# 2E0788
Girling 3/4" Bore kit part# 2E0787
This machined, billet aluminum cap with rubber bellows, stops fluid from venting and ruining painted surfaces. This component also helps keep
the fluid in place when going over hills and jumps and stopping the inclusion of
air into the braking system. For 1.75" outside diameter cast housing
(standard), and
not the obsolete large cast reservoir
models. Order part number #2F1275.
Caliper bleeder screws Look to Earl's Solo-Bleed for a better way of doing that necessary job!
Any of the reservoirs below may be used with a Girling remote master cylinders.
AP Racing
Just two of the popular AP series of master cylinders
CP6093 A master cylinder suitable for brake and clutch applications where space restrictions are not a primary concern. For most bore sizes, the longer available stroke versus the CP2623, makes it particularly suitable for some clutch installations.
CP2623 An extra short master cylinder suitable
for all brake and clutch applications, especially where space is restricted.1.0"
stroke
Two of the most popular series of AP Racing master cylinders are the CP6093
standard lightweight and the CP2623, extra short lightweight unit. 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 have and easy way of identifying the bore sizes of 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.
| Tie Wrap Color |
Bore Size |
| Black | 15.9mm (5/8") |
| Blue | 17.8mm (0.70") |
| Green | 19.1mm (3/4") |
| Orange | 20.6mm (13/16") |
| Red | 22.2mm (7/8") |
| White | 23.8mm (15/16") |
| Yellow | 25.4mm (1.0") |
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 there flimsy wire clips or snap rings for
attachment.
AP Reservoir #4709- series
3.5" H part# 2F0518
5.0" H part# 2F0186
7.0" H part# 2F1071
Don't forget the High Temperature Racing Brake Fluid!
Earl's Solo-Bleed bleeder screws are the best replacement for your standard
