BRAKES - HIGH BRAKE PEDAL TRAVEL OR LOW BRAKE PEDAL FEELISSUE

The brake pedal may feel low or there may be long brake pedal travel on some vehicles. This may be due to the master cylinder bore size.

SERVICE PROCEDURE

If adjustment is unnecessary or does not correct the concern, replace the master cylinder. Refer to the 1995 F-Series Service Manual, Section 06-06 for removal and installation procedures.
