What makes the D154-R caliper different from other cast models?

The D154-R caliper has a forged aluminum body and stainless steel pistons, which contribute to a lower deflection rate and higher volumetric efficiency. This means it's built to be more responsive and efficient than many heavier cast iron calipers.

What size rotors can this caliper accommodate?

This caliper is designed to work with rotors that are up to 12.19 inches in diameter and have a thickness ranging from 0.81 inches to 1.04 inches.

Does this caliper come with brake pads?

The manufacturer description states that this caliper uses standard metric D154 brake pads. These pads are not listed as included with the caliper itself, so you may need to purchase them separately.

Product Details

Wilwood is known for making serious braking components for performance and racing applications. This D154-R caliper is a prime example, built with a forged aluminum body that's Type III hard anodized for durability. It features stainless steel pistons and is designed to work with rotors up to 12.19 inches in diameter and 1.04 inches thick. The fluid inlet port is positioned directly behind the piston, which helps prevent any interference with the slide pins during installation or use.

Compared to heavier cast calipers, this D154-R offers a lower deflection rate and better volumetric efficiency, meaning it moves more fluid for a given input. This translates to a more responsive and consistent pedal feel. Even with a 2.50-inch piston option, this caliper weighs in at just 3.3 pounds, making it a lightweight choice for performance builds. It also uses standard metric D154 brake pads, which are widely available. The mounting setup is designed to work with stock height and offset, simplifying installation on many GM applications.
