Assumptions: This assumes you're working with drum brakes, which were more common on 1969 F250s. Disc brake installation is significantly different.
Tools You'll Likely Need:
* Jack and jack stands: Absolutely essential for safety.
* Wheel chocks: To prevent the truck from rolling.
* Lug wrench: To remove and install the wheels.
* Brake drum wrench: To remove the brake drums.
* Socket set and wrenches: Various sizes will be needed.
* C-clamp or brake spring compressor: For compressing the brake springs.
* Hammer and punch: May be needed to loosen stubborn parts.
* Wire brush: To clean parts.
* Brake cleaner: To clean brake components thoroughly.
* New brake shoes, wheel cylinders, hardware (springs, clips, etc.): Replace these parts as needed; don't reuse old parts. Get the correct parts for your specific axle.
* Torque wrench: Crucial for proper tightening of bolts and nuts.
* Grease: For lubrication of certain parts.
General Steps (Drum Brakes):
1. Safety First: Engage the parking brake, chock the front wheels, jack up the rear axle, and securely support it with jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Brake Drum: Use the drum wrench to remove the brake drum. It might be stuck due to rust; gently tap around the edges with a hammer to break it free. Be careful not to damage the drum.
4. Inspect the Components: Carefully examine the brake shoes, wheel cylinders, springs, and other parts for wear, damage, or leaks. Replace anything that's worn or damaged.
5. Remove the Old Brake Shoes: Using the C-clamp or spring compressor, carefully compress the brake springs to release the brake shoes. Remove the shoes and any old hardware.
6. Install New Brake Shoes: Carefully install the new brake shoes, ensuring they're properly seated and aligned.
7. Install Wheel Cylinders (if replacing): If you're replacing the wheel cylinders, carefully install the new ones, making sure to lubricate the seals and follow the manufacturer's instructions. Bleed the brakes afterwards (see below).
8. Reassemble the Brake Mechanism: Reinstall the springs, clips, and other hardware, following the correct order and ensuring everything is properly seated. Refer to a repair manual for the correct configuration.
9. Install the Brake Drum: Push the brake drum back onto the axle.
10. Install the Wheel: Replace the wheel and tighten the lug nuts to the proper torque specification.
11. Bleed the Brakes: This is crucial to remove air from the brake lines. This usually involves loosening the bleeder valve on each caliper or wheel cylinder while an assistant pumps the brake pedal. Refer to your repair manual for the correct bleeding procedure. A vacuum bleeder can make this easier.
12. Lower the Vehicle: Carefully lower the vehicle.
13. Test the Brakes: Test the brakes thoroughly before driving. Be cautious and gradually increase speed.
Important Notes:
* Repair Manual: A repair manual specific to your 1969 Ford F250 is indispensable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Parts: Ensure you get the correct parts for your truck. The rear axle configuration can vary.
* Safety: Brake work is crucial for safety. If you're unsure about any step, seek professional help.
This is a simplified overview. The actual process is more complex and requires attention to detail. Consult a reliable repair manual for your specific truck model before attempting this repair.
