Which vehicles does it fit?
It's a direct-fit replacement for listed Volkswagen models: Corrado, Passat, Eurovan, Jetta, Cabrio, Golf, Derby, and Van. Check the Buyer's Guide tab for exact years.
What are the key specifications?
An aluminum housing with a 0.875 in bore diameter, 4 outlets, and M10 x 1.0 outlet threads at a 1 mm thread pitch.
What are signs my master cylinder may need replacing?
A sinking or spongy brake pedal or brake-fluid leakage at the cylinder may signal a failing unit. Diagnose the cause first; if the master cylinder is at fault, this part replaces it.
