TILTON 76-625 Master cylinder 5/8″

DESCRIPTIONTilton master cylinders are engineered to provide optimum performance at a moderatecost. The master cylinders are made of lightweight aluminum and have a black anodizedcoating to prevent wear and corrosion. Tilton master cylinders set the standard for theindustry and are a direct replacement for master cylinders that have a 2.25″ spaced,2-bolt mounting pattern.The 76 Series master cylinders are specifically designed to be assembled withcustomer-supplied –4AN inlet fittings, hose and remote mount reservoirs. The inlet portis a 7/16-20 thread (–4AN) designed for a crush washer seal.  Installation Notes Mount the reservoir above the calipers to prevent fluid bleed-back from the calipersto the master cylinders.• Make sure that all parts are clean before assembling.• Inlet port thread is designed for 7/16”-20 fittings.• Top outlet is extra deep to work with 3/8”-24 banjo bolts to long AN3 fittings.INSTALLATIONMaster Cylinder1. Remove the dust plugs from the master cylinder inlet and outlet ports.2. The inlet adapter is pre-installed into the master cylinder a Tilton. Inlet adapter isdesigned for fittings with a 7/16” -20 thread. If inlet adapter is removed and needs tobe re-installed, the proper torque into the master cylinder body is 25 lb-ft.3. 76-Series master cylinders are shipped with AN3 plug installed into the rear outletport. If routing of the break lines out of rear ports is desired, remove plug and installinto top outlet port (unless port is being used for other purposes such as for pressuresensor, brake light switch, etc)4. Top outlet port is extra deep for use wit 3/8” -24 banjo bolts or long AN3 fittings.Direct Mount ReservoirTilton offers a direct mount reservoir (P/N 74-240) that is designed to mount to themaster cylinder in place of installed inlet adapter.1. Remove inlet adapter from master cylinder.2. Installed reservoir in place of removed adapter and torque to 25 lb-ft.Remote ReservoirTilton offer three remote reservoir options:• Single chamber remote reservoir (P/N72-230)• 3-chamber remote reservoir (P/N 72-577)• Low profile 3-chamber remote reservoir (P/N 72-578)1. Install 7/16”- 20 fitting into inlet port of master cylinder.2. Connect inlet fitting to remote reservoir using AN4 braided lines. BRAKE BLEEDINGRequired Equipment• Bleeder kit• Proper wrenches• An adequate supply of DOT 3 or 4 brake fluid• If the vehicle has a dual master cylinder brake system then both of thesystems must be bled simultaneously. See Bleeding Order section forproper order.Priming Master Cylinder1. Fill the master cylinder reservoir with brake fluid.2. Slightly loosen the fitting at the master cylinder.3. Gently depress and release the brake pedal until fluid emerges.4. Tighten the fitting.5. Select the bleeding order that fits your application from Bleeding Ordersection.Brake Bleeding1. Fill a clear bottle with enough brake fluid to keep the hose-endsfully 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 preventsucking 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 beenremoved from the system MAINTENANCEThe brake system should have the brake fluid replaced and the brake bleedingprocedure performed before each event.MASTER CYLINDER REBUILD KITSRefer to this table for the appropriate rebuild kit.BLEEDING ORDERFixed calipers, 2 Master Cylinders1.

Work your way in, bleeding the next closest caliper.Fixed calipers, 1 Master Cylinder1. Start at the caliper furthest from the master cylinder. Bleed the inboardside and then the outboard side.2. Proceed to the next closest caliper.Upon CompletionAfter bleeding, minimal brake pedal travel should beobserved. Properly bleeding the brakes does not requireany power equipment or a massive amount of appliedpedal force.
