Frequently Asked Questions

What does a brake master cylinder do?

It converts the force you apply at the brake pedal into hydraulic pressure that is sent to the brake circuits. If a failed master cylinder is the cause of a sinking or spongy pedal, this replaces it.

It's a direct-fit replacement for the 1987-1991 and 1994-1996 Ford E-250 Econoline, the 1987-1991/1993-1996 E-350 Econoline and Club Wagon, and the 1987-1995 Ford F-250 and F-350. See the Buyer's Guide tab for the full list.

Does it include a reservoir and sensor?

Yes. The reservoir and the fluid-level sensor are included per the catalog. Mounting hardware is not included.

Is this a remanufactured unit?

No. It is 100% new, built entirely from new materials and made to meet SAE International standards.

What is the housing made of?

The housing is aluminum, constructed to match the casting material of the original part for similar performance. All rubber components use an EPDM compound rated for glycol-based brake fluid.
