TRW PHA490 Brake Hydraulic Hose - Front, Front Left or Front Right

TRW Brake Hydraulic Hose PHA490

The TRW PHA490 brake hydraulic hose is a direct-fit replacement for select Audi A4, A4 Quattro, and S4 applications. Built for consistent brake-fluid transfer and stable pedal response, it is engineered to meet OE-level requirements for everyday road use.

Key Features

• DOT approved brake hose for road use
• EPDM rubber outer sleeve and hose construction
• Black finish with metal end fittings
• Low volumetric expansion for firmer pedal feel and shorter stopping response
• 100% zinc-coated end fittings to support brake-fluid flow and corrosion resistance
• Four-layer fabric reinforcement for flexibility and resistance to weather, fuels, and grease
• Built to meet or exceed OE standards and SAE J1401 / FMVSS 106 requirements

Detailed Description

TRW PHA490 is a brake hydraulic hose designed for front brake applications on select 2006-2009 Audi models. The hose uses EPDM rubber construction with metal fittings and a standard replacement design to support reliable hydraulic performance under normal braking loads. Its low expansion characteristics help maintain a more direct pedal response, while the reinforced multi-layer build adds flexibility and durability in demanding underbody conditions. This part cross-references Audi OE number 8E0611707G for the same application.

Compatible With 2006 Audi A4, front right; 2007 Audi A4, front right; 2007 Audi A4 Quattro, front left; 2007 Audi S4, front left; 2008-2009 Audi A4, front; 2008-2009 Audi A4 Quattro, front; 2008-2009 Audi S4, front. The TRW PHA490 is a practical OE-style choice for Audi A4 brake hose replacement and front brake hydraulic service.

What It Helps Fix

• Soft or inconsistent brake pedal feel caused by hose expansion
• Brake-fluid flow issues related to aging or corroded hose fittings
• Cracking, wear, or deterioration in the original front brake hose
• Brake service needs on Audi A4, A4 Quattro, or S4 front brake lines
• Corrosion concerns at the hose ends in exposed undercarriage locations

Installation Notes

Verify the vehicle position, year, and chassis/VIN notes before installation. This hose uses M10 x 1.0 thread size at end 1 and does not include grommets, brackets, or a shield. Inspect adjacent brake lines, banjo points, and mounting locations for wear before completing the brake bleed procedure.

Quality Assurance

TRW manufactures this brake hose to meet or exceed OE standards and international specifications including SAE J1401 and FMVSS 106. The design also reflects AMECA test results focused on low volumetric expansion, supporting consistent braking performance on compatible Audi applications.
