AERO4 Big Brake Rear Brake Kit For OE Parking Brake Description

AERO4 Big Brake Rear Axle Kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades on late model high performance vehicles. High capacity braking from the W4AR calipers, BP-10 compound pads, and oversized 14.00" rotors are matched to the OE master cylinder output, ABS function, and individual vehicle bias requirements. Enhanced brake performance, increased durability, and high-tech style compliment big wheel, tire, and suspension upgrades on customized vehicles and all others with increased brake requirements.

Forged Narrow Superlite 4R Big Brake Rear Brake Kit (Race) Description

This kit is configured for dedicated road racing on all 2010-2015 model Camaros, and the 2016-2019 SS models. It is the engineered match for the AERO6R/ST front race kits on vehicles intended for unrestricted road race competition. All emphasis is on matched front to rear balance, high durability, and high efficiency heat management, without adding unnecessary rotating or unsprung weight to the driveline and rear suspension. FNSL4R/ST calipers use a forged aluminum body and feature a Type III Mil-Spec, medium gray color hard anodized finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. Thermlock® pistons are used to reduce heat transfer from the pads to increase fade resistance, and extend service life by decreasing temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish. Caliper piston volumes are matched for full compatibility with the OE master cylinder output and ABS controls. The calipers are also fully compatible with manual brake conversions to balance bar pedals using appropriately sized master cylinders. Spec37 alloy GT series directional vane 12.88” rotors are dynamically mounted to the OE hubs with weight saving forged aluminum hats. As is with the calipers, the hats are hard anodized for superior wear resistance and extended service life at the load bearing surfaces. Mounting brackets, including all premium grade fasteners, secure the calipers to the uprights in the stock location with no modifications required. This championship proven system is completed with high temperature, high friction, race compound pads selected specifically by application. Installation requires the separate purchase of the stainless steel braided flexline kit that must be ordered according to the model year.
Note 1. Road Race kits contain high temperature racing pads. Extended low temperature use will cause premature rotor and pad wear. Note 2. Kit may fit some 18" wheels. Check wheel clearance diagram in kit installation instructions before purchase.
