Product Details

The Wilwood 200-4309 is a billet stainless steel caliper piston designed for use in Wilwood PS-1 series disc brake calipers. Measuring 1.00" in diameter x 0.52" in length, this precision-machined replacement piston is a direct-fit service component for PS-1 caliper assemblies including Wilwood part numbers 120-5453 and 120-5456.

Key Features:

  • Billet stainless steel construction — machined from a high-strength proprietary stainless alloy for superior durability and corrosion resistance
  • Low thermal conductivity — stainless material minimizes heat transfer from brake pads to caliper seals and brake fluid, helping to maintain consistent pedal feel
  • Heavy-wall design — added wall thickness resists backside deflection under high hydraulic pressure for a firm, responsive pedal
  • Bright machine finish — precision CNC-machined to close tolerances for a proper fit within the caliper bore
  • Piston diameter: 1.00" (25.4 mm)
  • Piston length: 0.52" (13.2 mm)
  • Compatible calipers: Wilwood PS-1 series (120-5453, 120-5456)

The Wilwood 200-4309 is an OEM-quality replacement piston ideal for caliper rebuilds and maintenance. Sold individually — verify quantity needed before ordering.

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

Easy shopping

Everything went good, order shipped out the next day. The prices were good but the shipping cost was way to high $25 dollars for 2 head gaskets and some bolts oil pan bolts.
