Mazda CX-3 Big Brake Kit Upgrade / TTSPORT Classic 5440
The Mazda CX-3 is the smallest SUV in Mazda's CX lineup, but the Singapore-spec car still packs the 2.0L SkyActiv engine and Mazda's G-Vectoring Control system — enough playful handling to make the factory brakes feel like the weak link. This case, sent in by our Singapore distributor, swaps the stock setup for a TT5440 four-piston caliper kit paired with a 330mm rotor.
The owner opted for the custom red version of the TT5440, a caliper built with a forged construction and racing-grade stainless pistons. It's one of the more popular Classic Series calipers both domestically and overseas.

Why It Works
A forged two-piece caliper body flexes less under pedal load than a stock cast unit, which is what firms up pedal feel once you're on the brakes hard. The 5440's four pistons — star-profile, without dust boots — spread clamping force more evenly across the pad than a single- or two-piston caliper, translating into more consistent bite.
More rotor, more heat capacity
Stepping up to a 330x28mm rotor adds mass and surface area over the factory disc, giving the system more thermal capacity before fade sets in — useful on a car that's meant to be driven with some enthusiasm through corners, per Mazda's own GVC pitch.
Fitment without spacers
The kit was matched to the CX-3 with a caliper bracket built specifically for this platform, so the rotor and caliper package lines up with the factory hub geometry. The source notes the parts "aligned perfectly" with the stock data during install.
- Forged four-piston caliper for a firmer, less flexy pedal
- 330x28mm Dacromet-coated rotor for added heat capacity and corrosion resistance
- Vehicle-specific bracket for a clean, spacer-free fit
- Stainless steel lines swapped in alongside the caliper kit
