A spherical braking system mounted on a drive shaft of a vehicle comprising a brake sphere pad positioned just above and below a brake sphere and resting on an at least one segment of a brake housing wherein, the brake housing includes a top segment and bottom segment coupled to mounting dogs by using screws. The instruments provide a low profile engagement with the implants and facilitate insertion while minimizing tissue retraction and exposure of the tissue and neural elements to the instrumentation in the approach to the disc space. The system may generally include a housing in which an object may be sprayed, a holder for holding the object, a discharging device for discharging coating material onto an object, a vessel for collecting andor treating overspray, and conduits and flow controllers for directing overspray to be reused. Since the camming action is horizontal only, practically no vertical forces are applied to the circuit board and a best-fit alignment between a circuit board and heatsink can be established and maintained.
