Buyer's checklist
What to check before buying a used brake master cylinder
- Verify reservoir port style, fluid level sensor connector pin count, and brake line flare port sizes and locations (metric vs imperial threads).
- Check bore size specifications, as vehicles equipped with heavy-duty tow packages or larger brake calipers use larger diameter master cylinder bores.
- Inspect primary and secondary piston bore seals for internal bypass leaks, fluid weeping at the brake booster mounting flange, or dark sludge build-up.
- Confirm whether the unit is designed for vacuum-assisted, hydro-boost, or electro-hydraulic brake systems.
