Toyota Alphard Big Brake Kit Upgrade / TTSPORT EPB 355mm Rotor
The Alphard is one of the most popular high-end MPVs on the road today, prized for its cabin comfort and its reputation as a safe, steady daily driver. But comfort-tuned suspension and brakes that were sized for a family hauler, not a performance build, mean the factory setup can feel soft and a little short on bite once the car is loaded up or driven with any urgency. For an owner looking to make an already well-built MPV safer and more capable at speed, upgrading the brakes is one of the more direct ways to get there.
This build is a full four-wheel brake upgrade: AP9660 six-piston calipers up front and AP9440 four-piston calipers at the rear, both paired with TTSPORT 355x32mm drilled rotors. The rear rotor gets a dacromet anti-rust coating, and the rear axle also carries a dedicated component to keep the factory electronic parking brake working with the new hardware.
Vehicle & Kit Specs
This is a mixed-brand setup by design — imported calipers matched with TTSPORT rotors — so the spec sheet below breaks out exactly what went on each axle.
| Item | Specification |
|---|---|
| Vehicle | Toyota Alphard (import MPV) |
| Front caliper | AP9660 six-piston caliper (imported, paired with TTSPORT rotor) |
| Front rotor | TTSPORT 355x32mm drilled two-piece rotor |
| Rear caliper | AP9440 four-piston caliper (imported, paired with TTSPORT rotor) |
| Rear rotor | TTSPORT 355x32mm dacromet-coated drilled rotor |
| EPB component | Electronic parking brake adapter for rear axle, keeps factory EPB functional |
As China's own brake-parts brands have matured, their rotors have closed the quality gap with established overseas names while staying tuned for domestic-market vehicles like the Alphard. Skipping the import duties and freight markup on the rotor side also means owners who still want an overseas caliper brand can build a setup like this one without paying import pricing on every component.
Why It Works
- Six-piston front and four-piston rear calipers clamp against more pad area than the factory calipers, giving a firmer, more progressive pedal instead of a soft, long-travel feel.
- The 355x32mm rotors add mass and swept-area over stock discs, which means more heat capacity for the rotor to absorb before the system starts to fade under repeated heavy braking.
- The rear axle keeps its electronic parking brake operational thanks to the dedicated EPB component, so daily-driver convenience isn't traded away for the upgrade.
- The dacromet coating on the rear rotor adds corrosion resistance beyond a bare cast-iron disc, and the drilled pattern was chosen to match the look of the imported calipers up front.
