Top Quality, widely known by its TQ abbreviation, is a trusted Canadian automotive parts brand with a legacy spanning over 40 years in the North American aftermarket industry. Manufactured and distributed by Transit Inc. — the largest auto parts warehouse in eastern Canada, operating since 1971 — Top Quality has earned its reputation as a go-to brand for reliable, cost-effective brake and related components. Their product lineup covers disc rotors, brake drums, drum brake hardware kits, brake shoes, and wheel cylinders, all engineered to OE-matched specifications to ensure consistent wear, long service life, and quiet operation. TQ rotors are cast from G3000 heat-flowed iron for the ideal balance of tensile strength and hardness, while their spring kits and brake shoes use OE-matched friction materials that have been independently tested for noise, vibration, and harshness (NVH) performance. Whether you're maintaining a passenger car, light truck, or trailer, Top Quality parts deliver dependable performance without breaking the budget.
