75-Series Master Cylinder Kits
Description
Tilton Master Cylinders are engineered to provide optimum performance at a moderate cost.
There are many congurations that can be assembled with the wide range of components.
The master cylinders are made of lightweight aluminum and have a black anodized coating
to prevent wear and corrosion. Two reservoirs are included in the kit; 7.0 ounce and 4.0 ounce.
Also included are a 3/16" inverted are tting and AN-3 line adapter. 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 pattern.
Installation notes
• Decide which reservoir size and style ts your application.
• The 4.0 ounce reservoir is recommended for clutch applications and brake systems used
in short races where brake pad wear is at a minimum.
• The 7.0 ounce reservoir is recommended for use on brake master cylinders when there is a
signicant amount of pad wear during an event. They also have more reserve capacity in
the event of a uid leak somewhere 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.

Master Cylinder
1. Remove the dust cover from the master cylinder reservoir opening.
2. Make sure that the o-ring is seated properly in the groove of the reservoir entry port on
the master cylinder body.
3. Apply a small amount of rubber grease (P/N: RG-17) onto the o-ring.
4. Do not damage the o-ring or move it out of position when installing the reservoir or the
remote tting.
5. Slide the selected reservoir or remote tting onto the master cylinder body along with
the wire clamp.
6. Place the wire clamp so that one wire of the clamp is above the o-ring and the other is
below the o-ring.
7. Do not over tighten the wire clamp or you may damage the reservoir or remote tting. It
should be "snug."
8. Insert the reservoir lter into the reservoir properly by referring to Diagram 1.
9. Thread the reservoir cap onto the reservoir to keep dirt out.
10. Select the appropriate tting for your application and attach this tting to the master
cylinder body.
11. Mount the master cylinder on the vehicle.
12. Proceed to the Brake Bleeding section.
Master Cylinder with Remote Mount Reservoir
1. Determine the location for mounting the remote mounted reservoir.
2. The supplied rubber hose can be cut to length. Select the location for the remote
mounted bracket accordingly.
3. After selecting the location for mounting the remote reservoir, drill the two 1/4" diameter
mounting holes on 1.20" centers.
4. Install the remote-mounting bracket with the appropriate hardware.
5. Apply a small amount of rubber grease (P/N: RG-17) onto the o-ring on the remote tting.
6. Do not damage the o-ring or move it out of position when installing the reservoir or the
remote ttings.

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 submerged.
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.

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.
