Features, Description, Q&A, Specs & Installation
OEM Fitment for Brake System Integrity. The OPR Master Cylinder Cap Diaphragm restores lost functionality in aging braking systems by sealing off the fluid reservoir from moisture and debris. This critical component helps maintain consistent brake fluid pressure, contributing to reliable pedal feel and braking response under all driving conditions. Engineered to match factory specifications, it offers a precise fit with factory caps.
Resilient and Fluid-Resistant Construction. Constructed from high-quality rubber compounds, this diaphragm is designed to withstand exposure to hydraulic brake fluid without degrading or cracking. It holds up under high-heat scenarios and keeps contaminants from compromising braking efficiency. Its molded design ensures tight tolerance for a reliable, leak-free seal.
Installation. This product installs by simply lifting the reservoir cap and placing the diaphragm inside. No tools or modifications are needed.
Application. This OPR Master Cylinder Cap Diaphragm fits 1984-1991 Corvette models.
