Wagner Brake Drum Brake Shoe Z637 is a rear drum brake shoe that presses outward against the brake drum to generate the friction that slows the wheel. It installs as a direct-fit replacement for the listed Saturn applications, covering the 1991-2002 Saturn SL, SL1 and SL2, the 1993-2002 SC1 and SC2, the 1991-1992 SC, plus the 1993-1999 SW1 and 1993-2001 SW2 (engine: All).
Features:
- OE-matched friction: uses OE-matched friction material for consistent braking performance.
- Precision-ground: the friction surface is precision-ground to maximize friction-to-drum contact.
- Organic, bonded lining: organic friction material bonded to the shoe, with a 0.190 in primary lining thickness.
- Built to spec: designed for a 7.090 in brake drum diameter with a 1.188 in shoe width; FMSI 1437-S637.
Mounting hardware and parking brake levers are not included with this shoe — consult the vehicle service information for the correct hardware and whether any existing pieces may be reused. Signs the shoes may need replacing include reduced braking, noise, or a low or soft pedal; if worn drum brake shoes are the cause, this replaces them. For even, balanced braking, it is best practice to replace the shoes on both wheels of the axle together as a matched set. Country of origin: China.
