MCP I. 3879.1 Billet Aluminum Cap with O-Ring

An optional, durable aluminum cap designed specifically for MCP brake master cylinders. It provides a reliable seal and protection.

Using this cap is easy. Just take off the old cap on your MCP brake master cylinder and put this new one on. Make sure it's properly seated. When it comes to maintenance, check the O - ring regularly for any signs of wear or damage. If the O - ring is worn out, replace it to keep the cap working well. Also, clean the cap with a mild cleaner to prevent dirt build - up. Avoid using harsh chemicals as they might damage the aluminum.
