Detailed Description

Centric designed the C-TEK Standard Brake Drums line to deliver many of the features associated with premium replacement parts while keeping the fitment straightforward for routine brake service.

What It Helps Address

• Brake pulsation caused by an out-of-round or worn drum
• Reduced rear braking performance from excessive drum wear
• Noise from uneven brake shoe contact on the friction surface
• Service issues when the drum exceeds maximum discard diameter
• Fitment problems from incorrect bolt circle or hub register dimensions

Installation Notes and Tips

Confirm the existing drum’s maximum brake diameter before reuse or replacement. Measure the hub register, bolt circle, and mounting hole diameter to verify alignment with the vehicle’s rear brake assembly. Inspect brake shoes, hardware, and wheel cylinders during service, and clean the friction surface before final assembly. For Honda Civic and Toyota Corolla applications, compare the original drum dimensions to part number 123.63001 to ensure proper fit.
