Models

1991-89 E250, E350, F250, F350.

Problem

Excessive brake pedal travel or brake pedal fade may occur during application, when heavily loaded or on steep downhill grades. This may be caused by the original brake caliper piston material.

Cause

According to Ford TSB 91-20-8, changing to phenolic piston equipped calipers may correct problem. Applies to 1991-89 E-250, E-350, F-250, F-350 trucks built prior to 5/1/91.

Solution

Before replacing calipers be sure to perform brake system tests that eliminate other possible vehicle problems that might cause the fade or excessive pedal travel. If adjustment does not correct concern, replace both calipers with phenolic piston equipped remanufactured units. Refer to CARDONE catalog for correct part numbers.
