Dorman - First Stop Brake Hydraulic Hose P/N:H621407
$26.99
Keep hydraulic pressure flowing to your Audi's front brake caliper with the Dorman - First Stop Brake Hydraulic Hose H621407. It installs as a direct-fit replacement for the 2007-2008 Audi RS4 [All] and 2003-2004 Audi RS6 [All], in the front left or front right position, and is precision-engineered to the original hose's fit, function and performance for that specific application. A brake hydraulic hose carries brake fluid from the vehicle's rigid brake line to the caliper while flexing with suspension and steering movement, so pressure reaches the brake when you press the pedal.
- Durable design: EPDM rubber hose with a protective jacket and specially coated, corrosion-resistant treated-steel fittings.
- Position-specific: manufactured to precise measurements for an exact fit and easy installation; 18.75 in overall length.
- Fittings: End 1 is male with a 10 mm thread; End 2 is female at M10 x 1.0.
- Quality assured: materials tested to government-regulated safety and durability standards; DOT approved.
Ships as the hose only — no bracket, gasket/seal, or mounting hardware; consult the vehicle service information for the correct sealing washers and fasteners and whether they may be reused. Cracking, bulging, chafing, or fluid leaks are signs the hose may need replacing. Country of origin: China.

It carries brake fluid from the vehicle's rigid brake line to the caliper while flexing with suspension and steering movement, delivering pressure to the brake when you press the pedal.
How do I know if my brake hose needs replacing?
Cracking, bulging, chafing, or fluid leaks at the hose are signs it may need replacement. If a failing hose is the cause of a soft or spongy pedal, this replaces it. Diagnose the cause first.
