Suzuki Jimny Big Brake Kit Upgrade / TTSPORT Slim Series
The Suzuki Jimny is famous for barely changing its formula for decades — body-on-frame construction, low-range four-wheel drive, solid axles, and a 1.3L naturally aspirated four-cylinder making 63 kW (about 84 hp) and 110 Nm of torque. That stubbornness is exactly why off-road owners love it, but the factory brakes were never really built with hard trail use or spirited street driving in mind. This Jimny picked up a TTSPORT vehicle-specific big brake kit built for its platform, aimed at fixing a soft pedal and rotor fade without giving up the stock 15-inch wheel fitment.
Low-range 4WD and solid axles make the Jimny a serious trail platform, but heavier off-road use and the added weight of aftermarket gear put real strain on a set of factory brakes designed decades ago.
Vehicle & Kit Specs
The upgrade swaps the factory single-piece rotor and caliper for a purpose-built TTSPORT setup, sized to clear the Jimny's stock 15-inch wheels with no spacers or wheel swap required.
| Item | Specification |
|---|---|
| Vehicle | Suzuki Jimny — fits stock 15-inch wheels |
| Front caliper | TTSPORT forged four-piston caliper, vehicle-specific for the Jimny |
| Front rotor | 290mm x 22mm vented, curved-slot rotor |
| Lines | TTSPORT stainless steel brake lines |
| Kit type | Direct-fit, vehicle-specific big brake kit |
Because the kit is engineered specifically for the Jimny, the caliper, rotor, and lines bolt in as a matched set rather than a generic universal fit.
Why It Works
The forged four-piston caliper uses a stiffer body than a cast unit, which means less flex under hard clamping and a more consistent, linear pedal feel through repeated stops on rough terrain.
- Forged four-piston caliper delivers stable clamping force and a more linear pedal feel than the stock single-piston setup.
- The 290x22mm vented, curved-slot rotor sheds heat faster than the factory solid disc, cutting down on fade during technical trail runs or long descents.
- Vehicle-specific fitment clears the stock 15-inch Jimny wheel — no spacers, no wheel change.
- TTSPORT stainless steel lines replace the rubber factory lines for a firmer, less spongy pedal.
