Overall Assessment

Customers highly rate our product for its quality and practicality, particularly in restoration projects and as a master cylinder for brakes. Its lightweight and non-rust features set it apart from typical cast iron cylinders, presenting both aesthetic appeal and durability. This makes install easy and maintenance-free. Many customers have replaced their former cylinders with ours, citing equivalent performance but superior quality. It notably added value to vintage cars like a 1955 Chevy. Consumers trust us as a reliable parts provider, choosing our products over competitors.

I had a cast iron master cylinder that worked well. What I did not like was the weight and the fact it started to rust a week after the installation. This puchase solves both concerns, and it well finished to boot. It performs as capably as the cast iron MC, and you won't have to apologize for the iron oxide.

Is this Master the deep or shallow bore type. In that, does it use the long or short pushrod. I see the part you suggest for a pushrod (91631946) so I'm assuming its the deep style? Is a shallow style available?
