| Wheels | 20-inch required for caliper and rotor clearance |
| Weight saving | About 28 kg off unsprung mass, front and rear combined |
Read this before you order
This is not a bolt-on stock replacement. The 410mm front rotor and large front caliper need 20-inch wheels to clear, so factory 18s won't work. The rear has to be built as a dual-caliper setup so the electronic parking brake keeps functioning — plan the rear at the same time as the front.
What you actually gain
| STOPFLEX feature | Why it matters on the AH30 | What you notice |
|---|---|---|
| 410mm front rotor + 10-piston caliper | A loaded Alphard carries a lot of weight, and the factory setup leans comfort over capacity. More rotor and more clamping area means more heat to absorb before the brakes start to fade. | The pedal stays firm and predictable on repeated stops and long downhill runs instead of going soft. |
| Carbon ceramic rotors, ~half the weight of steel | The van is already heavy, so every kilo you pull off the corners helps the suspension do its job. About 28 kg comes off unsprung mass here. | The ride settles quicker over bumps and expansion joints, which suits how an Alphard is meant to feel. |
| STOPFLEX ceramic pads, friction above 0.4μ cold | A people-mover gets driven from cold all the time — school runs, airport runs, short hops. You want bite from the first stop, not after a warm-up. | Strong, easy-to-modulate braking right away, with no cold-morning vagueness. |
| Low dust, rust-free rotor faces | Big wheels on a premium van show every bit of brake dust and every rust ring after rain. CCB keeps both in check. | Wheels stay clean longer and the rotor faces don't surface-rust after a wet week sitting still. |
What gets better
- More heat capacity for repeated hard stops and long grades
- Firmer, more consistent pedal under load
- Roughly 28 kg less unsprung weight for a cleaner ride
- Strong cold bite, normal even in deep cold on the first stop
- Very low brake dust with the matched STOPFLEX pads
- Rotor faces that don't rust after rain
What to confirm first
- Wheel size: this kit needs 20-inch wheels to clear
- Rear plan: dual-caliper setup to retain the electronic parking brake
- Your goal: this is a street comfort-and-confidence build, not a track package
- Pad pairing: run the matched STOPFLEX pads to get the low-dust and friction numbers

FAQ
Is a 10-piston front caliper overkill on an Alphard?
It isn't, given how the van is used. The Alphard is heavy and usually loaded with people and luggage, so it asks a lot of its brakes. The large fixed caliper and 410mm front rotor add heat capacity and keep the pedal consistent when you're braking hard repeatedly, like coming down a long grade.
Does this upgrade keep the electronic parking brake working?
Yes, as long as the rear is planned for it. On this build the rear runs a dual-caliper setup: a Brembo four-piston braking caliper plus a separate electronic parking brake caliper, so the EPB keeps working normally.
Why would carbon ceramic brakes improve ride quality on an Alphard?
A carbon ceramic rotor weighs about half what a same-size steel rotor does, so it cuts unsprung mass at each corner. That gives the suspension less weight to control, which helps the van settle more cleanly over bumps and broken pavement.
Will this kit fit behind factory 18-inch wheels?
No. The 410mm front rotor and large front caliper need the room, so this package requires 20-inch wheels for clearance.
How long do STOPFLEX carbon ceramic rotors last on the street?
A long time. In street-only use, away from the track, STOPFLEX carbon ceramic rotors can reach roughly 250,000 to 300,000 km depending on how you drive, your pad choice, and overall maintenance.
