76-Series Master Cylinder
DESCRIPTION
Tilton master cylinders are engineered to provide optimum performance at a moderate cost.
The master cylinders are made of lightweight aluminum and have a black anodized coating
to prevent wear and corrosion. Tilton master cylinders set the standard for the industry and
are a direct replacement for master cylinders that have a 2.25" spaced, 2-bolt mounting pat-
tern.
The 76 Series master cylinders are specically designed to be assembled with customer’s
supplied -4AN inlet ttings, hose and remote mount reservoirs. The inlet port is a 7/16-20
thread (-4AN) designed for a crush washer seal. The updated cylinder features dual-outlet
ports in a -3AN female taper seat, both at the rear and on the top.
Installation Notes
• A smaller (~4.0 oz) reservoir is recommended for clutch applications and brake systems
used in short races where brake pad wear is at a minimum.
• A larger (~7.0 oz) reservoir is recommended for use on brake master cylinders when there
is a signicant amount of pad wear during an event. The additional reserve capacity can
be benecial in the event of a uid leak in the system.
• Mount the reservoirs above the calipers to prevent uid bleed-back from the calipers to
the master cylinders.
• Make sure that all of the parts are clean before assembling.
INSTALLATION
Master Cylinder
1. Remove the dust plugs from the master cylinder inlet and outlet ports.
2. The inlet adapter is pre-installed in the master cylinder from Tilton.
If you need to remove the inlet adapter for any reason, the proper torque into
the master cylinder body is 25 f t-lb.
3. Select the appropriate inlet tting for your application and attach the tting to the
inlet adapter.
4. Mount the master cylinder on the vehicle and attach the vehicle brake lines.
5. The master cylinder is shipped with an -AN3 plug installed into the rear outlet.
If use of the rear outlet is desired for your application, the plug can be removed and
installed into the top outlet port. In addition, a pressure sensor or bleeder can be installed
in place of the plug.
Remote Reservoir
1. Select an appropriately sized remote mount reservoir for your application. It is recom-
mended that a reservoir with an integral -4AN outlet port is used. Tilton recommends one
of it’s popular 3-chamber reservoirs, available in Plastic (72-577) or Aluminum (72-570).
Use the reservoir guidlines from the Installation Notes above guidelines for choosing a
reservoir size.
2. Determine the location for mounting the remote reservoirs. Be sure to mount the
reservoirs above the calipers to prevent uid bleed-back from the calipers to the
master cylinders.
3. Choose a suitable inlet hose which is brake uid compatible.
4. Be sure that all of the parts are clean before assembling.
5. Install the inlet hose onto the inlet tting on the master cylinder and onto the
outlet tting of the remote reservoir.

BRAKE BLEEDING
Required Equipment
• Bleeder kit
• Proper wrenches
• An adequate supply of DOT 3 or 4 brake uid
• If the vehicle has a dual master cylinder brake system then both of the
systems must
be bled simultaneously. See Bleeding Order section for proper order.
Priming Master Cylinder
1. Fill the master cylinder reservoir with brake uid.
2. Slightly loosen the tting at the master cylinder.
3. Gently depress and release the brake pedal until uid emerges.
4. Tighten the tting.
5. Select the bleeding order that ts your application from Bleeding Order
section.
Brake Bleeding
1. Fill a clear bottle with enough brake uid to keep the hose ends sub-
merged.
2. Attach the other end of the plastic bleeder hose to the caliper bleed-screw.
3. Be sure the hoses stay submerged throughout the procedure to prevent
sucking air on
the return stroke of the pedal.
4. Depress the brake pedal with slow and gentle foot pressure.
5. Open the caliper bleed-screw.
6. Allow the pedal to drop to the fully depressed position.
7. Close the caliper bleed-screw.
8. Allow the pedal to return to the relaxed position.
9. Wait several seconds and then repeat steps 4 through 8 until air has been
removed from
the system.
MAINTENANCE
The brake system should have the brake uid replaced and the brake bleeding
procedure performed before each event.
MASTER CYLINDER REBUILD KITS
Refer to this table for the appropriate rebuild kit.
BLEEDING ORDER
Fixed calipers, 2 Master Cylinders
1. Front & rear passengers side, inboard
2. Front & rear passengers side, outboard
3. Front & rear drivers side, inboard
4. Front & rear drivers side, outboard
Floating calipers, 2 Master Cylinders
1. Front & rear passengers side
2. Front & rear drivers side
Floating calipers, 1 Master Cylinder
1. Start at the caliper furthest from the master cylinder.
2. Work your way in, bleeding the next closest caliper.
Fixed calipers, 1 Master Cylinder
1. Start at the caliper furthest from the master cylinder. Bleed the inboard
side and then the outboard side.
2. Proceed to the next closest caliper.
Upon Completion
After bleeding, minimal brake pedal travel should be
observed. Properly bleeding the brakes does not require
any power equipment or a massive amount of applied
pedal force.
