Detailed Description

Cardone 11-3045 is a remanufactured brake master cylinder engineered to match original equipment performance on select Volkswagen and Audi vehicles. It is a direct-fit hydraulic replacement for applications such as a 2001-2009 Volkswagen Jetta with Electronic Stability Program, a 2002-2010 Volkswagen Beetle with Electronic Stability Program, a 2002-2006 Volkswagen Golf with Electronic Stability Program, and a 2000-2003 Audi A3 with Vehicle Stability Control. This part number 11-3045 is also listed for the 2003-2004 Volkswagen R32, 2007-2010 Golf City, 2007-2009 Jetta City, 2010 Beetle Cabrio, and 2011-2013 Volkswagen Clasico.

The Cardone Brake Master Cylinder product line is remanufactured from OE cores and re-engineered to meet critical micro-finish requirements in the bores, helping reduce pitting and corrosion-related wear. Plastic reservoirs are vacuum-tested where applicable, and the remanufacturing process uses new rubber components that meet SAE specifications.

Common Brake Issues This Part Can Address

• Low or spongy brake pedal feel caused by internal master cylinder bypass
• Brake fluid leakage from the master cylinder body or rear seal area
• Uneven hydraulic pressure affecting braking response
• Hard pedal condition after a failed or contaminated master cylinder
• Brake warning symptoms tied to worn internal seals or bore wear

Installation Notes and Tips

Use the brake fluid specified by the original equipment manufacturer and always start with fresh fluid from a sealed container. Bench bleed the master cylinder before installation, and for step-bore designs, depress the piston slowly, release slowly, and wait 20 seconds between strokes rather than pumping the piston. Verify the booster push rod seal and inspect the rest of the hydraulic system for contamination, frozen calipers, or hose issues before final bleeding.

Compatible with 2001-2009 Volkswagen Jetta, 2002-2010 Volkswagen Beetle, 2002-2006 Volkswagen Golf, and 2000-2003 Audi A3 applications listed above. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Each Cardone remanufactured master cylinder is computer tested to confirm fit and function before release. The unit is re-engineered to OE performance standards, uses new O.E.-quality seals and cups, and includes corrosion-resistant treatment on cast-iron versions within the line to help extend service life.
