Default CCX3057 Brake Master Cylinder Question

Hi:

I'm looking to replace the brake master cylinder on CCX3057, as its leaking slightly at the actuator piston seal area :-(. In looking at my installation it differs significantly from my CCX manual (circa 1987).

I've attached a photo, does this look familiar to anyone out there? Other than some numbers cast into the body, there don't appear to be any other identifiers. I'm weighing my options on replacement in kind or a replacement of the entire pedal assembly, and I'd prefer the former first to just get things stopped safely before tackling something more complicated.

All that being said, I had some tuning work done on the motor (built 428, valve adjustment, carb, distributor) this week to get a baseline for a later dyno tuning run. This helped immeasurably, as before this my '02 Audi TT with 300+ hp was marginally faster than the Cobra. At the sugggestion of the tuners, I removed the air filter (way too small) for a brief test and WHOOOOOOOHOOOOO! did that ever wake things up, especially over 4000rpm. Very high on the smile-o-meter, and now I can see what all the excitement is over the perfromance of these cars. New air filter, here we come.

It also highlighted how important the brakes are. Any assistance on identifying my brake master cylinder wold be very much appreciated.

Thanks in advance.

Kirk

Does not look like my old Jaguar set up? Probably VW, toss them both. Easy to replace with new Wilwood and be done with it. That would be my suggestion.

Hi Mickmate/Jeff:
Thanks for both of your suggestions. My initial thoughts were to just replace in kind just to get back to functionality before upgrading but the wilwood suggestion sounds like a good move. Another opportunity.
