💡 Purchasing & Installation Tips

Since S850 primarily corresponds to parking brake shoes, please note the following:

Verify Physical Dimensions: The most critical step – always compare inner diameter (206.5 mm or 190 mm), width (45 mm), and thickness with the old part.

Check Included Hardware: Kits vary by brand.

Replace in Pairs: To ensure balanced parking brake force on the rear axle, always replace all 4 shoes on both sides together. One standard set meets this requirement.

Inspect Brake Discs: When replacing shoes, inspect the drum surface (inside the rear disc) for excessive wear or grooves. Damage requires replacement of the entire brake disc assembly.

Verify with VIN: Vehicle configurations may vary by model year and trim. The most reliable method is to provide the vehicle VIN (chassis number) to a professional parts supplier.
