Not ready for the expense of a Vanco brake up-grade, I opted to start with new brake pads by installing the ones used by racers: EBC Brakes.
The EBC brake pads are ceramic/kevlar fiber material and a direct replacement for the stock brake pads. EBC provides brake pads that will fit a wide range of applications. For my Wrangler, I opted for the Series 4000 (Yellow Stuff) pads as they are advertised as being the “...most grippy pad formulation”. While designed for closed circuit racing, the pads can be used on highway.
After about 500 miles of use, I can say that stopping ability has been improved and the cost was reasonable.
