Customers report high satisfaction with our product, due to its perfect fit, easy installation, and excellent replacement for older master cylinders particularly in historic automotive models such as the Ford Model A and the 1935 Ford Car. The product's quality and durability are consistently praised, with, for instance, its stainless insert impressions signaling extended lifespan. Despite some customers finding rust and grit within the cylinder that needed cleaning, they affirm the overall function and quality remain unaffected. The significant customer preference is notably shown in their willingness to repurchase from the brand, in contrast to issues experienced with competitors' products. Our master cylinder's practicality and superior manufactural quality set it apart.

Great product at a good price
Easy to install Looks like original The inside of cyl had grit some rust. Must take apart and clean. Other than taking a little extra to take apart and clean, great part. But the grit would cause premature failure and cost someone lots of grief!

Second master cyl in one year
I should of checked this brand new cyl . The cyl a small amount of core sand and a lot of rust under the fill reservoir . The first one failed at one year, fooled me once, ordered another from S-W motors . The second one showed the same thing ! Took it apart cleaned till spotless. Put in on my 40 coupe . Called speedway , the guy was ok but i never got any feed back on my concern about the other masters in stock of the same part number. They should all be checked for rust and sand, does not take long , this is a brake issue!

This m/c fit well and appears to be of good quality. I'm using it on a Model A with juice brakes and it replaced the original '48 Ford part I was using.

This is on a car that isn't driven very often. I had a standard master cylinder from another supplier that rusted and pitted in less than a year. This stainless lines cylinder should last the life of this car.
