2020 Suzuki Swift SZ-T Dualjet Mhev CVT 1.2L Hybrid electric (clean) · AV70 SWO

A clear pattern of front brake wear has emerged on this Swift, with the most recent MOT on 10 June 2026 passing only after four advisories were recorded against the nearside and offside front brake discs and pads. Both front discs were noted as worn though not yet excessively, and both front pad sets were flagged as wearing thin. Prior tests in June 2025, June 2024, and October 2023 all returned clean passes with no advisories whatsoever, indicating that this brake wear is a recent development rather than a long-standing chronic issue. Mechanically, the simultaneous wear on both sides points to normal service-related pad and disc consumption rather than a seized caliper or sticking slider, but the fact that both axles have reached advisory threshold at the same time means a complete front brake overhaul including discs and pads is imminent. At roughly 2,356 miles per year over six years, this Swift has covered exceptionally low mileage for its age, and the MOT record reflects a consistent annual testing cadence with no significant lay-up gaps between 2023 and 2026. Such low annual accumulation typically means light use, predominantly short journeys, and prolonged standing periods between drives. The mechanical implications of this usage profile are specific and worth weighing carefully. Short trips prevent the engine, catalytic converter, and underbody from reaching full operating temperature, which can encourage condensation in the exhaust system and moisture retention in the engine oil. Long stationary periods meanwhile can accelerate corrosion on ferrous underbody components, harden suspension bushes, and degrade the 12V battery through repeated partial state-of-charge cycling, particularly relevant given the mild-hybrid system which relies on a healthy auxiliary battery for its stop-start and torque-assist functions. Brake discs on low-mileage vehicles are also prone to corrosion pitting on the friction surface even when pad wear is low, so the disc advisories here warrant particularly close inspection. Given that the front brakes have only just crossed into advisory territory, a prospective buyer should expect to budget for front discs and pads within the next few thousand miles and should physically inspect the wear on a viewing. Feel for any lipped or rusted edge on the disc outer circumference, check that pad material visible through the caliper window still has reasonable thickness, and look for any scoring or blueing on the disc surface which would indicate overheating. On a test drive, listen for any grinding or squealing from the front wheels under light braking, and watch for judder through the brake pedal or steering wheel which would suggest disc runout or uneven wear. Bind or sticking can also be detected by rolling the car at low speed with the handbrake released and feeling for any residual resistance from the front wheels. Beyond the brake items, attention during a viewing and test drive should focus on the symptoms associated with low-mileage use. With the ignition active listen for any warning lights related to the hybrid battery system and confirm the engine starts promptly without excessive cranking, as a sluggish start would point to a degraded 12V battery. Check the exhaust tailpipe for heavy black soot or unusual moisture drips after a cold start, and inspect the underbody edges, subframe, and brake pipe unions for any surface corrosion that may have developed during periods of standing. On the move, listen for any clonks or knocks from the front suspension over uneven roads, particularly from the anti-roll bar bushes and drop links, and pay attention to steering precision since stiff or cracked suspension components often manifest as vagueness or a knocking sensation through the wheel. The CVT transmission should also be evaluated for smooth, step-less acceleration with no slipping, juddering, or whine, all of which would warrant closer investigation given the hybrid-assisted drivetrain.
