This front JK Big Brake kit includes:
-Calipers The oversize twin-piston brake caliper provides for more clamping force, with an increased surface area while decreasing brake fade. The oversize caliper will provide a more efficient method of heat dissipation for increased stopping power.
- High-performance 13.3" mill-balanced vented rotors keep the braking system cool for maximum stopping in all conditions. The dual wheel bolt pattern 5 on 5" and 5 on 5.5" allows for use on multiple wheel applications. A premium e-coat finish is durable and resists rust.
-Pads are high performance optimized to provide maximum surface area and reduce brake dust and noise during extreme braking. The composite-resin, semi-metallic pads increase the lifetime of the brake system.
****The Heavy Duty Master cylinder Part# 4303450 is highly recommended on all JKs and may be required for those Jeeps with overly soft pedal.**** 2007-2011 JKs have a greater need and we highly recommend this master cylinder for those applications. 2012+ JKs feature a larger factory master cylinder and may not need a larger master cylinder kit.
