Rear Disc Brakes (F-Super Duty and F-Series Stripped Chassis Only) The rear disc brakes are self-adjusting. They do not require service other than periodic lubrication of the caliper slide rails and inspection for pad wear. Hydraulic Power Brakes The hydraulic brake system is made up of two independent hydraulic circuits. One hydraulic circuit supplies fluid to the front disc brakes and the other hydraulic circuit supplies fluid to the rear drum brakes. These two circuits are supplied by a common hydraulic brake fluid reservoir, with a fluid level sensor. The brake light in the instrument cluster will light for low brake fluid in the common brake fluid reservoir. RWARNING An increase in pedal travel will result in reduced braking capability. The brake system should be checked immediately. Rear Anti-lock Brakes Except for F-Super Duty and F-Series Commercial and Motorhome Stripped Chassis, F-Series Light Trucks are equipped with a Rear Antilock Brake System. This system prevents at least one and often both rear wheels from locking up when the brakes are applied in a panic stop, for example. Even with the Anti-lock Brake System, you should be careful when braking. Front brake lock up on any surface, even on smooth pavement causes loss of steering control. Heavy braking on roads with loose surfaces such as 146
