What size rotors can this Wilwood caliper accommodate?

This PS-1 caliper is designed to fit rotors with diameters ranging from 6.00 inches up to 9.00 inches. It also accommodates rotor thicknesses between .15 inches and .20 inches.

What makes the pistons in this caliper unique?

The caliper uses two stainless steel deep cup pistons. These are specifically designed to help reduce heat transfer from the brake pad to the brake fluid, which can help maintain consistent braking performance.

Product Details

When you're building a custom braking system or upgrading a smaller vehicle, finding a compact and strong caliper is key. The Wilwood PS-1 caliper is designed for just that, offering a lightweight, low-profile solution that doesn't sacrifice stopping power. It's built with a cast aluminum body, keeping the overall weight down to just over half a pound, which is great for reducing unsprung mass.

Inside, you'll find two stainless steel pistons. These aren't just any pistons; they're deep cup pistons designed to help keep heat from transferring from the brake pad to your brake fluid. This helps maintain consistent braking performance, especially during repeated stops. The caliper also uses high-temperature square seals to manage how the piston retracts, ensuring smooth operation. Plus, Wilwood routed the brake fluid passages internally, so there are no external tubes to worry about, keeping the design clean and protected.

This PS-1 caliper is versatile, fitting rotors with diameters from 6 to 9 inches and thicknesses from .15 to .20 inches. It's a solid option for many custom applications where space and weight are considerations.
