The SP 255 PR rear brake pads (Hi-Q series from Sangsin Brake) are designed for high-performance executive and business-class sedans. These pads were developed to withstand the heavy weight of Mercedes-Benz vehicles of that era, ensuring consistent deceleration without overheating.

Technical Description and Applicability
This model is an equivalent to the original spare parts for the rear axle of the following series:

Mercedes E-Class (W210): 1995–2003 (including the high-performance E420 and E430 models).

Mercedes S-Class (W140): 1991–1998 (the legendary "wild boar," all models from S280 to S600).

Mercedes SL (R129): 1992–2001

Wear Sensors: This brake pad model supports the installation of electronic wear sensors (usually purchased separately). The housing is equipped with corresponding grooves.

Recommendation: When replacing the rear brake pads on S-Class (W140) models, be sure to check the condition of the parking brake pads, as they are located inside the drum portion of the disc and are replaced separately.

Important Note: The PR series is positioned as the optimal price-quality ratio for servicing older premium vehicles, providing factory-standard safety at a lower cost.
