How does the dual-piston design affect braking performance?

Dual pistons provide a wider, more uniform force distribution across the brake pad, helping improve pad wear and brake modulation under typical driving loads. This design helps the pad maintain consistent contact with the rotor for steady deceleration.

• Two pistons apply force across a broader pad surface for balanced wear.
• Reduces localized pad glazing and uneven rotor scoring.
• Improves pedal feel and modulation compared with single-piston rear calipers in similar applications.

What are the key specifications and installation notes?

Confirm measurements and your vehicle’s brake configuration before purchase. This caliper uses metric thread fittings and specific bracket dimensions that must match your hub assembly and brake pads.

• Piston outer diameter: 1.772 inches
• Inlet port size: M10 x 1.0; Bleeder port size: M10 x 1.0
• Center distance between bracket holes: 102 mm; pad guide slot width: 395 mm
• Check whether your original caliper is single- or dual-piston; GM brake codes are on the Service Parts Identification sticker
