2024-2026+ Toyota Alphard / Vellfire (AH40) CCB Big Brake Kit — Genuine Brembo GT BM6 6-Piston Caliper Front + Genuine Brembo GT BM4 4-Piston Caliper Rear Setup
The 2024-2026+ Toyota Alphard / Vellfire AH40 is a heavy luxury van, so repeated high-speed stops, mountain descents, and loaded family use can put more heat into the factory iron brakes than the OE system was designed to dissipate. This StopFlex kit replaces the factory brake package with 405mm front carbon-ceramic rotors, Genuine Brembo GT BM6 6-Piston Calipers, 380mm rear carbon-ceramic rotors, and Genuine Brembo GT BM4 4-Piston Calipers for greater heat capacity, lower brake dust, and reduced rotating mass. Each kit is built only after the exact AH40 trim and wheel package are confirmed, because bracket geometry, rotor-hat offset, and caliper clearance are not treated as universal across the Alphard / Vellfire family.
- 405mm front carbon-ceramic rotors require 21-inch or larger wheels on the AH40 Alphard / Vellfire; spoke clearance is checked separately from wheel diameter.
- Front braking is handled by the Genuine Brembo GT BM6 6-Piston Caliper with a 405mm rotor, a size chosen for the heat load of a large premium people mover rather than a compact performance car.
- The rear axle uses a Genuine Brembo GT BM4 4-Piston Caliper with a 380mm carbon-ceramic rotor, so rear brake torque and visual balance are engineered with the front system instead of being left stock.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 405 mm front rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine Brembo GT BM6 6-Piston Caliper, which spreads clamping load across a larger pad area than a single-piston sliding caliper and supports a firmer, more consistent pedal under repeated braking. Brembo GT hardware is a known performance-brake architecture, and the fixed multi-piston body gives the 405mm carbon-ceramic rotor the caliper stiffness and pad control needed for a heavy AH40 Alphard / Vellfire.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo GT BM4 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep rear brake contribution matched to the larger front system. Because the AH40 uses an electronic parking brake, rear fitment is engineered around EPB retention rather than treated as a generic rear caliper swap.
Front & rear, engineered together: The 405mm front and 380mm rear carbon-ceramic package is engineered as a complete brake system so front bite, rear stability, pedal travel, and ABS behavior remain predictable. A front-only conversion on a heavy AH40 can leave rear torque, heat capacity, and appearance out of step with the primary brake upgrade.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit every 2024-2026+ Alphard or Vellfire AH40?
No. The kit is built for your confirmed AH40 year, model, trim, drivetrain, and wheel setup. StopFlex does not assume platform-wide fitment; brackets, rotor-hat offsets, caliper mounting, lines, and hardware are specified for the exact vehicle submitted before production.
What wheel size is required for the 405mm front rotor?
The 405mm front rotor requires 21-inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke clearance, wheel offset, and caliper profile against the Genuine Brembo GT BM6 6-Piston Caliper before approving the order.
Will the electronic parking brake still work?
Yes, the AH40 rear package is engineered around EPB retention. The rear Genuine Brembo GT BM4 4-Piston Caliper and 380mm carbon-ceramic rotor configuration is not sold as a generic rear swap; parking-brake compatibility is part of the vehicle-specific design review.
Why use carbon-ceramic rotors on an Alphard or Vellfire instead of larger iron rotors?
Carbon-ceramic rotors reduce brake dust and rotating mass while giving the AH40 more heat capacity for repeated braking with passengers, cargo, or larger wheels. The payoff is cleaner open wheels, more stable pedal feel during repeated stops, and less weight at the hub than an equivalent large iron package.
