Overview
A hot rod builder gets a machined, chrome plated master cylinder with a one inch bore, tested under vacuum for reliability. The family it belongs to works with disc and drum brake set ups and mounts to many stock brackets or Tuff Stuff universal brackets.
The reason to choose it is a ready to bolt show finish backed by a vacuum test on every unit. The limitation is that diaphragm style and mounting details are not given for this model number, so a builder must confirm them before ordering.
Who it's for
A hot rod, custom or muscle car project with a disc, drum or mixed brake set up that matches this bore. Buyers who need a different bore, or a bolt pattern they have not verified, should check the maker before ordering.
Pros and cons
- Chrome plated finish
- Vacuum tested every unit
- All new components
- Works with disc and drum set ups
- Reservoir style not listed
- Bolt spacing not given for this model
- Single bore size only
Performance notes
Pedal feel and line pressure are governed by bore diameter, because a given bore moves a set volume of fluid per stroke to the calipers or wheel cylinders. The listing says each unit is vacuum tested, which checks the seals before shipping.
