Product Details

- Vehicle application: compatible 1988–1998 GM 1/2-ton trucks and SUVs

Brake System & Fitment
For A0463, the supplied gold fitting remains in the port closest to the power booster. The factory brake lines are installed in the opposite ports from their original master-cylinder positions, which can require careful re-forming of the lines. Confirm vehicle, ports and complete brake-system configuration before ordering.
Bench Bleeding Required
Bench bleed A0463 in a vise before installation. Install a bench-bleed kit, fill with DOT 3 or DOT 4 brake fluid, and slowly stroke the piston until no air bubbles remain. Continue for approximately 10 additional strokes after the bubbles disappear. Do not let the master cylinder run dry, and bleed the complete brake system after installation.
