Installation Notes and Tips

Verify caliper type and axle position before ordering, especially on Volvo 740 and 760 models with ATE rear calipers and Mercedes-Benz applications with Bendix or ATE rear calipers. Porsche 911 fitment varies by year and brake package, including front cast iron M calipers on select front applications and an exception for the Turbo Look Package on 1978-1983 rear fitment. Confirm the vehicle year, make, model, and brake configuration against the fitment list before installation.
