Lightweight, reliable, and built specifically for the demands of youth racing, this black anodized billet aluminum dual piston caliper delivers consistent, confidence-inspiring stopping power race after race.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThe 650QB is the black anodized version of the popular MCP 650Q — same proven internals and performance, with a sleek black finish. It fits the majority of quarter midget chassis on the market today, making it a go-to choice for builders, crew chiefs, and parents setting up new cars or replacing worn components.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eDual pistons provide even, balanced clamping force across the rotor, which translates to straight, predictable braking without pull or fade. The included AN-3 straight fitting makes for a secure, leak-resistant brake line connection, and the 5\/16\" mounting holes align with standard QM brake mount configurations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eImportant:\u003c\/strong\u003e This caliper is designed for use with DOT 5 silicone brake fluid only.
