Reservoir Required: When upgrading your master cylinder, you will need an external reservoir to house the excess brake / clutch fluid. The easiest way is to purchase a brake reservoir mounting kit, which has all hardware, hose, clamps, etc included. You can also purchase the reservoirs or tubing separately if you want to custom fit your own. Banjo Bolts Required: When upgrading your master cylinder, you will need new banjo bolts to connect the master cylinder to your brake lines. Choose a single banjo for OEM brake line configurations (one line to the right caliper with a crossover). Choose a double banjo for dual line configurations (one line to each caliper). For race applications, the banjo bolts do not have pressure switches. For street applications, we recommend banjo bolts with pressure switches that allow you to activate the brake lights. Brake Fluid Required: Don't forget to purchase some Brake Fluid at the same time, since you will need to re-bleed your brakes after installing your new brake master.
