2025-2026+ Tesla Model Y / Performance (Juniper Refresh) CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The 2025-2026+ Tesla Model Y Juniper owner shopping this kit is usually trying to add real thermal capacity beyond the factory iron brake package while cutting brake dust and unsprung mass on a heavy dual-motor EV. This StopFlex kit pairs 380 mm carbon-ceramic rotors with a Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper up front and a TTSPORT EP4 4-Piston Caliper with EPB on the rear, so the front and rear axles are engineered together instead of mixing a front-only upgrade with stock rear hardware. Each kit is built for the confirmed Model Y or Model Y Performance Juniper trim, including bracket geometry, rotor-hat offset, line routing, and wheel-clearance review.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels; wheels under 19 inches will not clear the rotor package, and spoke clearance must still be checked.
- The front axle uses the exact Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, selected for a 380 mm rotor package on the 2025-2026+ Model Y Juniper chassis.
- The rear axle uses a TTSPORT EP4 4-Piston Caliper with EPB so the Juniper Model Y retains electronic parking-brake function while adding rear thermal capacity.

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 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" 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 upgrade uses the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, a six-piston fixed caliper that spreads clamping load across a larger pad area for more stable pedal response and heat management than a small factory sliding-caliper layout. Its credibility comes from being a genuine OEM-derived Brembo performance caliper rather than an unproven generic casting. StopFlex adapts this caliper to the confirmed Model Y Juniper trim with matching brackets, 380 mm carbon-ceramic rotor geometry, hats, lines, pads, and hardware.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB to add rear braking capacity without deleting the Model Y’s electronic parking brake. Its four hydraulic service pistons support rear-axle stability under hard braking while the dedicated EPB actuator preserves factory parking-brake convenience.
Front & rear, engineered together: A 380 mm front CCB conversion on a Model Y Juniper should not be treated as a cosmetic front-only caliper swap because EV weight, regen blending, and rear-axle stability all depend on the system working as a matched package. StopFlex pairs the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper with the TTSPORT EP4 rear EPB caliper so rotor mass, pad choice, caliper position, and hydraulic balance are engineered together for the confirmed trim.
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 my exact 2025-2026+ Model Y Juniper or Model Y Performance Juniper?
StopFlex does not assume a universal Model Y fit. Before production, your exact trim, wheel package, hub/knuckle configuration, rotor-hat offset, caliper bracket position, and line routing are confirmed so the kit is built for your vehicle rather than the platform name alone.
What wheel size is required for the 380 mm carbon-ceramic rotors?
The 380 mm rotor package requires 19 inch or larger wheels. Wheels under 19 inches will not clear the rotors, and spoke clearance still has to be verified against the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper and rear TTSPORT EP4 caliper.
Will the electronic parking brake still work?
Yes. The rear TTSPORT EP4 4-Piston Caliper with EPB uses four hydraulic service pistons for braking and a dedicated EPB actuator piston, so the Model Y Juniper keeps electronic parking-brake function while gaining a matched rear big-brake setup.
Why choose carbon-ceramic rotors on a Model Y Juniper instead of another iron rotor upgrade?
Carbon-ceramic rotors reduce brake dust, resist corrosion, and lower rotating and unsprung mass compared with iron rotors while adding high-temperature stability for repeated hard braking. On a heavy electric crossover, the payoff is cleaner wheels, more consistent heat behavior, and less mass at each corner when the kit is correctly matched to the vehicle.
