Produced by Nissan, Z32 is a chassis designation for the 300ZX model. 300ZX was first introduced in North America in 1990. It was powered with a powerful 3.0L engine that could get the car to rather high speed. Respectively the car required a good braking system.
One of the key components of your car is the brake system, where the brake caliper operates like a small hydraulic clamp designed to grab and grip the brake rotor and bring the car to a full stop. The brake caliper is a U-shaped device that has either one or more pistons on both sides of the U.
Brake Caliper Service
To get to your brake caliper you need to perform some steps. Raise and support either rear or back of vehicle and remove the wheels. Then disconnect the brake tube and hand brake cable from the caliper assembly. Remove the caliper mounting bolts and the caliper. To install, reverse the procedure. Nissan Z32 was equipped with two different models of brake calipers, AD7HA assembly and OPZ11V assembly.
