Dorman - First Stop Brake Hydraulic Hose P/N:H621102
$27.99
Keep firm, responsive braking reaching the front wheels with the Dorman - First Stop Brake Hydraulic Hose H621102. This flexible hose drops in as a front left or front right replacement across a broad range of BMW models, including the 2008-2013 128i, 2008-2013 135i, 2007-2013 328i, 2007-2013 335i and 2009-2016 Z4 — see the Buyer's Guide tab for the full list.
It carries pressurized brake fluid from the chassis hard line to the caliper while flexing with steering and suspension movement. If a cracked, bulging or leaking original hose is behind a spongy pedal, this replaces it as part of a complete brake job.
- EPDM rubber build: flexible EPDM rubber hose with a rubber outer jacket.
- Treated-steel fittings: coated, corrosion-resistant fittings — Male End 1, Female End 2.
- Measured to spec: 21.63 in overall length, a 10 mm End 1 thread and an M10 x 1.0 End 2 fitting for a position-specific fit.
- DOT approved: materials tested to government-regulated safety and durability standards.
No mounting hardware, bracket, gasket or seal is included. Sold individually; replacing both front hoses as a matched pair is good practice for balanced braking. Country of origin: China.
