The Beringer versus Grove cost discussion is a bit more complicated and in depth than is shown in this thread.
The Aircraft Spruce kits mentioned above do not include master cylinders/hardware or a PB and or anti skid valve. The 4 master cylinders alone are around $1700.
The kits with PB valves that are purchased through VANS/ASF include several hundred dollars of additional components such as the PB Cable, Bowden Clamps, B Nuts, and machined CNC brackets to hold the PB cables.
Kits from ASF/Vans include all prefabricated brake lines and fittings.
Kits from ASF/Vans also have a new upgraded integrated axle nut/extension.
Kits from ASF that include a PB valve, now also include an upgraded CNC braket with integrated microswitch for a "PB SET" indication on your EFIS
As Beringer's largest aftermarket wheel/brake distributor for RV specific components, ASF currently offers the Sensair TPMS system at no charge (a $750) value with the purchase of any complete Beringer system.
In short, the Vans complete Beringer system upgrade provides a good value for builders that are looking for a Beriger system with their initial kit order.
For builders that are currently "Free Agents" who have either deleted all brake systems or are looking to upgrade their stock brake system to the Beringer system, please reach out to us. We are happy to discuss the options available.
For builders that are wanting to install a Control approach rudder pedal system, or are wanting to include an ALIR anti skid valve with their setup, please reach out to us as there are some differences required from a brake line standpoint from the setup that Vans currently offers.
Hope this helps and Happy Building.
