4-Piston Caliper: Caliper Body:
Made of forged 6061-T6. Light weight at only 4.5lbs, these new RB4000 calipers are re-designed and built for the toughest brake jobs with extended service life before any rebuild is required.
Low Profile:Together with RB Center-Mount design two-piece rotors, you hardly even need to require a spacer to install the kit. It fits under 16' wheel for 300mm rotors.
Piston Material:Made of stainless steel instead of aluminum commonly used by other caliper mfgrs which can substantially reduce the heat transfer (approx 1/10 of aluminum) from the pad to brake fluid. Pistons are vented to further reduce the heat contact area and improve air circulation thereby reducing more heat transfer.
Dust Seal:Our dust seal is of built-in type (instead of external boot type) uniquely designed to shield the dust and foreign material from contamination and will not rip - as commonly seen on boot type dust seals.
Hardware:Brake pad pins and banjo connections were re-designed for easier brake line connection and brake pad replacement.
Surface Coating:Powder coating with most durable finish for lasting appeal.
Hardware:Most hardware is made of stainless steel for durable performance and appearance.
Never Get Lost Bleeder Cap:Newly designed with a retaining loop so you will never have to find it again and/replace the lost ones. (made of durable EPDM)
Use standard FMSI brake pads (D647):A very common P/N (same as WRX 4-pot fix pistons calipers, plenty of choice for suppliers and compounds.
Adapter:7075-T6 Aluminum Alloy
Rotor Design Convergent vane designThe cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler.
Center-mount design The center-mount flanges for hat mounting to the rotor ring have several benefits - It allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).
- The stress load transferred from the ring to the hat is balanced.
- Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface.
- Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges.
- Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.
- True floating design Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.
