Keep your rear brakes seated, quiet, and moving freely with the Dynamic Friction Company Disc Brake Hardware Kit (P/N 340-31020, also written 34031020). This rear-position kit supplies the fresh mounting and retention hardware that helps your rear disc brakes install correctly and operate the way they should. It fits a wide range of BMW models, including the 2004-2010 525I, 2006-2007 525XI, 2008-2010 528I, 2009-2010 528I XDRIVE, 2008 528XI, 2004-2007 530I, 2006-2007 530XI, 2009-2010 535I XDRIVE, 2008 535XI, 2007-2018 X5, and 2008-2019 X6 — see the Buyer's Guide tab for the full application and engine list.
DFC engineers this disc brake hardware kit for demanding brake-corner conditions:
- Corrosion & chemical resistance: holds up against road salt, moisture, and brake-service chemicals.
- High heat resistance: designed to withstand the elevated temperatures generated at the brake corner.
- Low coefficient of friction: helps components slide freely so pads move as intended.
- Easy assembly & removal: intended to simplify the install and future service.
Refreshing worn or corroded hardware during a rear brake job helps promote even pad movement and consistent operation. If rattling, dragging, or uneven wear traces back to tired brake hardware, this kit replaces it.
