What size rotors does this Wilwood PS-1 caliper fit?

This caliper is designed to work with rotors that have a diameter between 6.00 inches and 9.00 inches. It also accommodates rotor thicknesses ranging from 0.15 inches to 0.20 inches.

What are the pistons made of and why is that important?

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

Does this caliper require external brake line connections?

No, this PS-1 caliper features internal crossover brake fluid passages. This means there are no external crossover tubes needed, contributing to a cleaner installation.

Product Details

What you get with this Wilwood PS-1 caliper is a compact, lightweight (weighing just .93 pounds) brake caliper designed for performance. It's built with a strong cast aluminum body and features a sleek, low-profile design that tucks away nicely. This caliper is set up to work with rotors that are between 6.00 inches and 9.00 inches in diameter, and it handles rotor thicknesses from .15 inches up to .20 inches. The caliper itself has a .190 inch disc thickness specification.

Inside, you'll find two stainless steel pistons. These deep-cup pistons are a smart touch because they help reduce how much heat transfers from the brake pad to your brake fluid. This is important for keeping your brakes working consistently, especially during harder use. It also uses high-temperature square piston seals, which help manage how the piston retracts after you release the brake pedal. Wilwood also routed the brake fluid passages internally, so there are no external crossover tubes to worry about, keeping the overall package neat and tidy.
