Womala Front Brake Hose 30681723 Flexible Brake Line for Volvo C30 C70 Brake Auto Parts
The Front Brake Hose (Flexible Brake Line, OE Number: 30681723) is a critical hydraulic component for Volvo C30 (including C30 ELECTRIC), C70 (06–), S40 (04–), and V50 models. Installed between the front brake calipers and the rigid brake lines of the vehicle’s hydraulic system, it serves as a flexible connection that accommodates the front wheel’s movement (e.g., steering and suspension travel) while transmitting high-pressure brake fluid. As an OE-grade part, it meets Volvo’s strict safety and performance standards, ensuring precise fit, leak-free fluid transmission, and compatibility with the vehicle’s brake system, which is essential for reliable braking.
Constructed from durable, pressure-resistant materials: the inner layer is made of nitrile rubber or thermoplastic to handle brake fluid (resisting corrosion and degradation), while the middle layer features high-strength synthetic fibers (e.g., aramid) for reinforcement—capable of withstanding brake fluid pressure up to 1,000–1,500 psi. The outer layer is a weather-resistant polymer that protects against road debris, UV rays, and moisture, preventing premature wear. Both ends are equipped with precision-machined metal fittings (e.g., banjo bolts) to ensure tight, leak-proof connections with the calipers and rigid lines.
Core Functions
Hydraulic Fluid Transmission: Delivers pressurized brake fluid from the master cylinder (via rigid lines) to the front brake calipers, converting hydraulic pressure into mechanical force that clamps the brake pads against the rotors—enabling the vehicle to slow down or stop safely.
Flexibility for Wheel Movement: Unlike rigid brake lines, its flexible structure allows for the front wheel’s steering and suspension movement (e.g., when turning or driving over bumps) without breaking or restricting fluid flow, ensuring consistent brake performance in all driving conditions.
Safety Protection: The reinforced design prevents hose expansion under pressure (which would cause a soft brake pedal) and resists damage from road hazards, maintaining reliable brake response and avoiding potential brake failure.
Compatible Vehicles
This Front Brake Hose (OE: 30681723) is tailored for the following Volvo models and year ranges:
Model
Applicable Year Range
Volvo C30 / C30 ELECTRIC
2007–2013
Volvo C70 (06–)
2006–2013
Volvo S40 (04–)
2004–2012
Volvo V50
2004–2012
Notes: Front brake hoses are position-specific (left vs. right front) and may differ in length or fitting angle even for the same model—confirm the exact position (left/right) via your vehicle’s VIN (Vehicle Identification Number) or Volvo’s official parts catalog to avoid fitment issues. During installation, replace old copper washers (on banjo fittings) with new ones to ensure a leak-proof seal, and thoroughly bleed the front brake system to remove air bubbles (air in the system causes a soft brake pedal and reduced braking efficiency). Inspect the hose regularly for signs of damage (e.g., cracking, bulging, or fluid leaks)—replace it immediately if damage is found, as a faulty brake hose poses severe safety risks. Avoid bending or twisting the hose during installation, as this can restrict fluid flow or weaken the reinforcement layer.
Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
