Brake Adapters (Probe Style)
$58.50 – $585.00
“Probe” style brake adapters are designed to cover the majority of vehicles on the road today. Each adapter is color-coded for quick identification by vehicle type. To create a pressure-tight seal, simply rotate the serrated black nut—this expands the probe’s O-ring inside the reservoir neck.
BAK5 Kit includes BA01, BA02, BA03, BA04, and BA05.
BAK8 Kit includes BA01, BA02, BA03, BA04, BA05, BA10, BA13, and BAH1.
