This flexible hose is a direct-fit replacement built to the measurements of the original rear brake hose for many 2006-2013 BMW models — including the 128i, 135i, 135is, 325i, 328i, 328i xDrive, 328xi, 330i, 335d, 335i, 335i xDrive, 335is, 335xi, M3 and X1 — in the rear left, rear right and rear inner positions (engine: All). See the Buyer's Guide tab for the full application list.

  • Durable design: made with EPDM rubber and specially coated, corrosion-resistant treated-steel fittings.
  • Position-specific: manufactured to precise measurements (8.12 in overall length) for an exact fit and easy installation.
  • Female fittings both ends: End 1 has a 10 mm thread; End 2 measures M10 x 1.0.
  • Quality assured: DOT approved and materials tested to government-regulated safety and durability standards.

The hose carries hydraulic pressure from the rigid brake line to the caliper; if a cracked, bulging or leaking original hose is your problem, this replaces it.
