Product Details

The Wilwood 120-11028 is an HM5 Hydra-Mechanical floating mount disc brake caliper designed for demanding rear brake applications on utility vehicles, ATVs, snowmobiles, and other powersports equipment. Engineered with a combined hydraulic and mechanical (parking brake) actuation system, this single-piston caliper delivers reliable stopping power in a compact, lightweight package.

Key Features:

  • HM5 Hydra-Mechanical Design: Dual-function caliper supporting both hydraulic service braking and mechanical parking brake actuation in a single unit
  • Left-Hand Floating Mount: Designed for left-side installation with a 3.00" mount center spacing
  • 1.19" Stainless Steel Piston: Single piston with 1.06 in² area; stainless construction provides low heat transfer and excellent corrosion resistance
  • Die-Cast Aluminum Body: Cost-effective yet rigid die-cast construction results in a lightweight and durable caliper at just 2.4 lbs
  • Clear Anodized Finish: Protective clear anodize coating for long-lasting durability and corrosion resistance
  • Dust Boot Included: Factory-fitted dust boot protects the piston seal from contamination
  • Compatible with 0.19" Rotor Width: Supports rotors from 6.00" to 11.20" in diameter (0.15" minimum to 0.19" maximum rotor width)
  • Pad Area: 1.7 in² pad area with 0.26 in³ pad volume for consistent friction performance

The HM5 caliper utilizes advanced design and manufacturing techniques to produce a unit that is both rigid and lightweight — making it well-suited for rear brake setups where both service and parking brake functionality are required. Compatible with Wilwood's HM-series brake pads and rotors.

A+ Experience. Made a mistake and almost canceled my order thinking that I've found better price. They were very nice to proceed with cancellation, but when I figured out my mistake, they did reverse cancellation without any problems. Prompt and polite response every time. I will use them again for sure.

Autoplicity is the best. Always easy, always good prices.
