Chevy Optra Brake Disc

• Manufactured to OE specifications using high tensile strength G3000 gray cast iron
• Coated with black zinc finish
• Maintains a flat and parallel pad wear and avoids the record grooves or galling common with non-slotted rotors

• 4 x 114.3 mm bolt pattern
• 256 mm disc diameter
• 12.6 mm bolt size
• 22 mm minimum thickness

• Manufactured to meet QS and ISO quality system standards
• Utilizes an electrocoating finish that provides long lasting corrosion protection
• Designed to withstand 400 hours of salt water exposure without rusting
• Double disc grinding ensures parallelism, eliminates run out, and provides near perfect disc thickness
• The double disc grinding also leaves a non-directional finish on the friction surface area for more effective pad-disc break in while providing quieter and smoother stops
• Center-split core casting offers proper heat transfer and thermal efficiency for superior braking and safety
• 100 percent fully machined hat delivers better disc balance
• Mill-corrected to a tolerance of less than 2 oz. per inch
