Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2025-2026+ Tesla Model Y (Juniper Refresh). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2025-2026+ | Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
Winter & Cold-Weather Braking
Winter question, straight answer: untuned ceramic discs bite less when cold. StopFlex optimized the pad compound and the rotor's ceramic coating for cold operation, so cold-start braking in winter feels very close to warm-weather braking. Extra following distance on freezing first stops is still smart; severe-winter daily cars should run Street Spec.
Caliper Overview
Front Caliper
The front uses the Brembo OEM Ford Shelby GT350 Mustang 6-piston caliper, a monoblock factory-homologated caliper built for repeatable clamping and consistent pedal feel over the 380mm front rotor.
Rear Caliper
The rear runs the TTSPORT EP4 4-piston forged caliper with an integrated EPB. It adds four 28mm hydraulic service pistons for real rear-axle thermal capacity while a dedicated 27mm actuator piston preserves your factory electronic parking brake, so the Model Y keeps OE park-hold on hills. The two-piece forged-aluminum body weighs about 4.50 kg per caliper without pads; the EP4 is matched to the 380mm rear rotor and your wheel/spoke clearance.
Choose Your Rotor: Street, Track-Day, or Motorsport

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.
Heat Management Note
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.

FAQ
How does this carbon ceramic kit behave in winter cold starts?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stop or two. That is physics, not a defect. StopFlex tunes both the pad compound and the disc's ceramic coating for cold starts, so cold-car feel on this Model Y now comes very close to summer feel. On the coldest first stops of the day, leave a little extra following distance until the front 380mm rotors have taken a few applications.
Will this fit my exact Model Y trim, or is it a platform-wide bolt-on?
It is not a platform-wide bolt-on. The Juniper Performance can differ from other Model Y trims in front upright and hub geometry, so brackets, rotor-hat offsets, and caliper mounting are engineered to your confirmed trim before anything ships. Send your VIN and trim and we build the kit to that specific car.
What wheel size do I need to clear these rotors?
The front and rear rotors are both 380mm, so 19-inch wheels are the minimum. Wheels under 19 inches will not clear the calipers, and spoke design also matters, so we check your specific wheel against the Brembo GT350 front caliper and TTSPORT EP4 rear caliper during fitment.
Does the kit keep my electronic parking brake?
Yes. The Juniper Model Y uses a factory electronic parking brake, and the TTSPORT EP4 rear caliper has a dedicated actuator piston built to retain that OE function. You keep automatic park-hold and hill assist while gaining rear-axle braking capacity.
