Something like these Wilwood pieces might work: https://pitstopusa.com/i-23931013-wilwood-compact-remote-master-cylinder-inlet-adapter.htmlThings are going forward. I've start the design of the integration of the Bolt booster brake and master cylinder in the Vanagon.
The Bolt cluster will sit just over the master cylinder.
The most challenging part will be to find another brake fluid reservoir or modified the original Bolt reservoir.
It need to fit under the cluster and don't touch it (in blue on the picture).
Do someone have advice to weld / fix a Chevy Bolt plastic reservoir to ''any other'' plastic reservoir?
If not, you may have to machine some hose adapters to mimic the fitting on the base of the stock reservoir(s) to connect to a remote reservoir like this https://www.amazon.com/17-2878-BRAKE-RESERVOIR-PLASTIC-67-up/dp/B004C3DV5C
A neat trick is to mount the reservoir somewhere in the line of sight, as your driving, behind a viewing slot in an access cover to keep an eye on the fluid level . Maybe include a small light to view it at night. Another option is to find an OEM remote reservoir that has a float switch that lights a warning light, when the fluid is too low.
Or, use something like this aftermarket unit: https://www.europaspares.com/2-chamber-brake-reservoir-with-fluid-level-switch.html
