3. Instal·lació (Configuració)
Installation of brake components requires specialized knowledge and tools. If you are not experienced in automotive brake system repair, it is highly recommended to seek professional assistance. Improper installation can lead to brake failure and serious injury.
Precaucions de seguretat:
- Utilitzeu l'equip de protecció individual (EPI) adequat, incloent-hi ulleres i guants de seguretat.
- Assegureu-vos que el vehicle estigui ben recolzat sobre els gats elevadors sobre una superfície plana.
- No treballeu mai sota un vehicle suportat només per un gat.
- El líquid de frens és corrosiu; eviteu el contacte amb la pell i les superfícies pintades.
- Do not allow air into the brake system during the process.
Passos generals d'instal·lació (consulteu el Manual de servei per obtenir més informació):
- Preparació: Gather necessary tools, new brake fluid, and a brake bleeding kit. Position a drain pan to catch old brake fluid.
- Treure la mànega vella: Carefully loosen and remove the banjo bolt or flare nut connections securing the old brake hose to the caliper/wheel cylinder and the brake line. Be prepared for brake fluid to leak.
- Instal·leu una mànega nova: Position the new Dorman H38432 brake hose, ensuring it is not twisted or kinked. Securely attach the fittings to the caliper/wheel cylinder and the brake line. Torque fasteners to manufacturer specifications.
- Sistema de frens de purga: After installation, it is critical to bleed the brake system to remove any air that may have entered. Follow the vehicle manufacturer's recommended bleeding procedure. This typically involves starting with the wheel furthest from the master cylinder and working closer.
- Inspeccionar si hi ha fuites: After bleeding, pump the brake pedal several times and hold pressure. Visually inspect all connections for any signs of brake fluid leaks.
- Prova de conducció: Perform a low-speed test drive in a safe area to confirm proper brake function before normal operation.

4. Funcionament
The Dorman H38432 Brake Hydraulic Hose is a passive component within the vehicle's braking system. Its primary function is to transmit hydraulic pressure from the brake lines to the brake caliper or wheel cylinder, allowing the brake pads or shoes to engage and slow down or stop the vehicle.
There is no direct "operation" by the user for this component. Its proper function is integral to the overall braking system's performance. A properly installed and functioning brake hose ensures consistent and reliable brake pedal feel and stopping power.

5. Manteniment
Regular inspection of brake hoses is crucial for vehicle safety. Brake hoses are subject to wear and tear from heat, road debris, and constant flexing. Over time, they can degrade, crack, or swell, leading to brake system issues.
Pautes d'inspecció:
- Inspecció visual: During routine vehicle maintenance (e.g., tire rotations, oil changes), visually inspect the entire length of the brake hoses for:
- Cracks, cuts, or abrasions on the outer rubber layer.
- Bulges or swelling, especially when the brake pedal is depressed.
- Signs of fluid leaks around the fittings or along the hose.
- Kinks or twists that could restrict fluid flow.
- Corrosion on the metal fittings.
- Comprovació del nivell de líquid: Regularly check your brake fluid reservoir level. A consistently low level without obvious leaks elsewhere might indicate a slow leak from a hose.
- Sensació del pedal de fre: A spongy or soft brake pedal can be a symptom of air in the system, often caused by a leaking hose, or a hose that is expanding under pressure.
If any signs of damage or degradation are observed, the brake hose should be replaced immediately by a qualified technician. Do not attempt to repair a damaged brake hose.
