Euclid Wedge Brake Piggyback Chamber

The Euclid Wedge Brake Piggyback Chamber handles the parking brake side of a tandem wedge brake setup, using a Type 9/12 piggyback design with a threaded clevis connection. This is not a standard S-cam chamber because the brake type and apply hardware are built around wedge brake operation. Its 5.55-inch outside diameter, 5.25-inch length, and 1.75-inch stroke place it in a very specific chamber category for Haldex-style wedge brake service. The piggyback section matters during parking brake repair because spring force, stroke, and thread fit all have to match before the brake returns to normal holding action. The Euclid E-PB0912 fits the wedge brake position where parking force and chamber fit must line up together.
