Detailed Description

TRW PML440 is a brake master cylinder for Dodge Sprinter 2500 and Dodge Sprinter 3500 models from 2003 through 2006. The aluminum housing, 25.4 mm bore, and two-piston layout are specified for hydraulic brake system replacement where the original master cylinder has worn internal seals, reduced pedal response, or fluid leakage. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Brake fluid leaking from the master cylinder body or outlet area
• Sinking or inconsistent brake pedal feel caused by internal seal wear
• Reduced hydraulic pressure in the brake system
• Contaminated or bypassing master cylinder internals
• Brake warning symptoms tied to master cylinder failure

Installation Notes and Tips

• Verify the vehicle is a 2003-2006 Dodge Sprinter 2500 or 3500 before ordering.
• Inspect the brake booster, lines, and fittings during replacement.
• Bench bleed the master cylinder before final installation to reduce trapped air.
• Confirm the M12 x 1.0 outlet connection matches the vehicle brake line setup.
• Use new seals and proper brake fluid handling practices during service.

Quality Assurance

TRW brake hydraulics are built to meet the dimensional and functional requirements of the listed Sprinter applications. PML440 is specified with the bore, port, and material details needed for direct brake system replacement on the confirmed fitment vehicles.
