Brake Floater Left Rear Single Shear

The Brake Floater Left Rear Single Shear caliper bracket (WM200-16LSS) is a heavy-duty OEM-specification replacement designed for GM metric brake systems. Built from steel with black powder coat finish, this rear driver-side mount uses a floater design with dual bearing support to distribute caliper load evenly across the mounting surface. Single shear construction provides direct load path to the vehicle frame, critical for maintaining brake responsiveness under sustained high-temperature conditions.

The dual-bearing floater configuration allows the caliper to self-center on the rotor, reducing uneven pad wear and extending brake pad and rotor service life. Black powder coat protects against corrosion from road salt, moisture, and brake fluid spray—essential for vehicles operating in coastal or harsh winter environments. Weighing 9.34 lbs, this bracket kit is engineered to OEM tolerances for direct bolt-on installation without modification to existing frame attachment points. Single shear design is preferred over dual shear in rear brake applications where space is constrained and maximum component stiffness is required.

This component is ideal for fleet maintenance, professional brake service shops, and enthusiasts rebuilding or restoring GM vehicles with metric brake calipers. Proper rear caliper bracket selection is critical for safety—incorrect brackets or worn mounts can cause rotor runout, uneven braking force distribution, and potential brake fade. The WM200-16LSS meets GM specifications for fitment and load capacity, making it a reliable choice for vehicles requiring OEM-level brake system integrity.

GM metric caliper systems are common across mid-range and full-size GM truck and SUV platforms. Rear brake mounting brackets wear and crack due to thermal cycling, road impacts, and the high stress generated during towing or loaded hauling. Replacement with OEM-specification hardware ensures brake system balance and safety performance. The floater design is particularly valuable for vehicles experiencing heavy trailer braking, off-road use, or extended mountain driving where sustained thermal loads degrade inferior brackets.
