Wilwood Master Cylinder Rebuild Kit 1-1/6-Inch Bore

When a tandem master cylinder needs attention, choosing a rebuild kit with the right bore is more relevant than buying a generic brake component. The Wilwood 260-4896 is identified as a tandem master cylinder rebuild kit with a 1-1/6-inch bore, which gives buyers a specific starting point for checking whether it matches the part they need. The listing provides little detail beyond that, though, so matching the bore alone should not be treated as confirmation of vehicle fitment.

Key specifications

This is an auto part, specifically a rebuild kit for a tandem master cylinder. Its listed bore is 1-1/6 inch. The package measures 8.0 inches long, 7.0 inches wide, and 2.0 inches high, and weighs 4.21 lbs. Those are package measurements and weight, not dimensions or weight for the master cylinder itself. The listed country of origin is the United States.

The key buying detail is the bore size and the stated tandem-cylinder application. The product information does not identify included components, supported vehicles, installation instructions, or a part-by-part contents list. From the way it is set up, this listing suits a buyer who already has a specific rebuild need in mind, rather than someone trying to identify a brake-system problem from scratch. For brake work, confirm the required part against the existing cylinder or reliable vehicle documentation before ordering.

Who it’s for

A solid pick if you have already identified a tandem master cylinder with a 1-1/6-inch bore and are looking for a rebuild kit rather than a complete replacement cylinder. For example, someone working through a planned brake-system repair can use the bore and application in the product name to narrow down the part search before comparing it with the cylinder’s markings or service information.

The alternative is replacing the complete master cylinder instead of rebuilding it. That approach may make more sense when the existing unit is damaged or its condition and serviceability are uncertain, but this listing does not provide enough detail to compare repair scope or included parts. You may want to skip it if you cannot verify the bore and application, or if you need a kit with a clearly documented contents list before starting the job. The listing also gives no vehicle-specific fitment information, so the product name alone is not a compatibility guarantee.

Everyday use

The kit is intended for a rebuild task, not for general maintenance or as a stand-alone upgrade. Before starting, make sure the job calls for a tandem master cylinder rebuild and that the stated bore matches the unit being serviced. The available details do not explain which components are supplied or how the repair is performed, plan around that information gap rather than assuming the package includes every part or instruction you need. If you are not equipped to assess or service brake components, having a qualified professional handle the work is the safer route.

Questions before you buy

Does this kit fit my vehicle? The listing does not name compatible vehicles. It identifies a tandem master cylinder application and a 1-1/6-inch bore, so vehicle fitment still needs to be confirmed separately.

Is this a complete master cylinder? The product is described as a rebuild kit, not a complete master cylinder. The specific pieces included are not listed in the supplied details.

Are the listed measurements for the part? No. The 8.0-by-7.0-by-2.0-inch measurements and 4.21-lb weight describe the package, not the cylinder.

Final verdict

This Wilwood kit is worth considering when the repair plan already calls for a tandem master cylinder rebuild and the 1-1/6-inch bore matches the unit being serviced. Its most useful detail is also its main boundary: the listing gives an application and bore but no vehicle fitment or contents breakdown. If either of those is still uncertain, identify the cylinder and confirm what the repair requires before choosing this kit over a complete replacement or another repair approach.
