Jack's Comments:

This new reproduction master cylinder and cap that we painted correctly is very close to the originals.  It has the dimple close to the front brake line port, domed hex head stop bolt and has a cap that is exactly like the originals.  This is a great option for anyone who wants a production looking disc brake master cylinder but doesn't want to shell out $600+ for an rebuilt original production master cylinder. 

We also offer the concours correct special red finish locking flange nuts to secure the master cylinder to the brake booster.

Concours Questions:
Q. Whats not correct about this master cylinder and cap?
A. The cap is very accurate and would pass for concours trailered judging. Its not an exact reproduction since it doesn't have the Bendix logo cast on the bottom, part number and date codes on port side of master cylinder.

Q. Why was the areas around the brake line ports not painted?
A. When the master cylinder was painted it had plugs in the ports to keep them clean before installation. When the master cylinder was painted it still had the plugs in place so they are bare steel. If you take a look at the low mileage example in our Factoid section you will see this same bare steel area around the ports that rusted differently from the rest of the master cylinder.

Q. Did some very early production cars have this cap on the master cylinder?
A. No, some very early cars had the 1968 master cylinder cap.

Q. Is the decal on the lid of the master cylinder cap correct for my 1967 Shelby?
A. The decal is correct for late 1967 the majority of 1968 production after the recall. If you have 1967 it should have a slightly different decal. Marcus detailed the differences in his disc brake master cylinder cap article. We have not found a source for an accurate version of the early decal.

Install Tips:
Installing a power brake master cylinder is always a bit of pain. We suggest you loosen or remove the four booster stud nuts under the dash that mount it to the firewall and remove the one bolt to the right of the booster. This will allow you to turn it slightly towered the engine so you can slip in the master cylinder on without damaging the mounting studs, pushrod and avoid scratching up the shock tower. Never bleed your brakes on a power brake car with it running. The pedal will over extend the rod and break internal plastic parts in the booster. This is not covered under our warranty.

Brake Fluid:
The manufacture recommends using synthetic DOT 3 or DOT 4 brake fluid. Silicone DOT 5 is not recommenced and will void warranty. Interesting post about DOT 5 fluid over swelling brake cylinder seals.

Your 6-month limited warranty period begins on the date of purchase. We will replace your master cylinder with a new one from our stock.
