Overview
A car builder or restorer fitting a new brake system gets this Wilwood tandem master cylinder, with a one inch bore and an integral reservoir in burnished aluminum. It is sold as a kit with the dimensions and weight listed.
Bore and stroke are stated, which is what matters when sizing a brake system. Port sizes, mounting pattern and kit contents are not listed.
Who it's for
Builders sizing a hydraulic brake system who know the cylinder bore they need. Someone replacing a factory master cylinder by vehicle has no application data here.
Pros and cons
- Bore and stroke listed
- Port sizes not listed
- Kit contents not itemized
- Vehicle fit not stated
Performance notes
Bore sets the pedal feel and pressure for a given caliper size, while stroke sets how much fluid moves per pedal push. A tandem design runs two circuits so a leak in one leaves the other working.
