Brake Pad Set Overview

The Dynamic Friction 4000-0639-00 is a DFC HybriDynamic disc brake pad set built for consistent pedal feel, strong brake response, and low-noise daily driving. It is a fitment-based replacement for select BMW and Ferrari applications, including BMW 840Ci brake pads and BMW 850Ci brake pads.

Key Features

  • Hybrid friction material for balanced stopping performance.
  • Integrally molded pad attachment for stable construction.
  • Low dust and low noise characteristics for everyday use.
  • Prepared for electronic pad wear sensor applications.
  • Outer and inner pads share the same 119.9 mm width and 17 mm thickness.

Detailed Description

DFC 4000 HybriDynamic brake pads are formulated to deliver predictable brake response without sacrificing comfort in normal street use. The hybrid friction compound is paired with an integrally molded design to support consistent contact and controlled wear, while the low-dust, low-noise characteristics help keep maintenance and brake noise concerns in check. Part number 4000-0639-00 is listed for rear Ferrari 550 Maranello applications and front BMW 840Ci and BMW 850Ci applications, with a sensor note for the BMW 840Ci fitment.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Brake noise during daily driving.
  • Excess brake dust buildup on wheels.
  • Inconsistent pedal feel under normal use.
  • Wear sensor-equipped brake service needs.
  • Replacement needs for BMW 840Ci, BMW 850Ci, and Ferrari 550 Maranello brake service.

Installation Notes

Fits 1997-2002 Ferrari 550 Maranello, rear. Fits 1994-1997 BMW 840Ci, front; the fitment note specifies required sensor 341-31020. Fits 1994-1997 BMW 850Ci, front, and also fits 1993 BMW 850Ci, front, from 8/93. Verify rotor condition, caliper operation, and sensor requirements before installation. Part number 4000-0639-00 should be matched to the listed fitment and notes before service.
