To upgrade a classic Ford to a dual circuit brake system, first assess the current system by inspecting the master cylinder design for compatibility and examining brake lines for damage. Gather tools such as wrenches, a brake line bending tool, and acquire a dual master cylinder, proportioning valves, and stainless steel brake lines. Elevate the vehicle, remove wheels, and detach old brake components carefully. Install the new dual master cylinder, ensuring secure attachment and proper brake line routing. Integrate a proportioning valve for optimal balance. Test brakes vigorously to confirm sound installation and performance. More technical insights can follow this robust overview.
Assess Your Current Brake System
Check your classic Ford's current brake system before switching to a dual circuit system. Start by looking at the master cylinder. Its design will show if you can directly replace it. Most classic Fords have a single circuit system. You will need to change the whole system for a dual circuit one. Measure the bore size of the master cylinder to ensure it matches or improves hydraulic pressure.
Look over the brake lines. Check for rust or damage. Dual circuit systems might need extra lines to separate the front and rear brakes. See if the wheel cylinders and calipers work with a dual circuit setup. Older models may have drum brakes. You might need to switch to disc brakes for better performance.
If your car has a brake booster, check if it has enough vacuum pressure and if it fits with dual circuit master cylinders. Do some research on your specific car model. Some classic Fords might have unique parts needing special solutions.
Write down any changes that have already been made to your car. This check will help keep your car safe and running well after the upgrade.
Gather Required Tools and Parts
Next, gather the tools and parts you'll need to upgrade your brake system to a dual circuit setup.
You'll need a set of wrenches, a tool to bend brake lines, a tool to flare them, and a kit to bleed the brakes. These tools help you install and adjust everything just right. A torque wrench is also needed to make sure everything is tightened properly.
For parts, start with a dual master cylinder that fits your classic Ford.
You'll also need brake proportioning valves to balance the brake pressure between the front and rear. Get new brake lines, preferably stainless steel ones because they last longer and don't rust quickly. Choose brake fluid that works well for high performance.
Consider buying a conversion kit from a well-known brand.
These kits usually include everything you need and are easier to install. Check out different options by looking at quality and customer reviews to find the best one for your needs. Proper preparation will help you switch to a safer brake system.
Remove Old Brake Components
Start by lifting the car with jack stands to keep it steady.
Take off the wheels for a clear view of the brakes. Check the brake lines, wheel cylinders, and master cylinder to see what shape they're in. Use a wrench to loosen the brake lines and watch out for leftover brake fluid. Make sure to get rid of the old fluid safely and in a way that's good for the environment.
Next, take out the master cylinder. Unbolt it from the firewall, being careful not to mess up any nearby parts.
Handle the wheel cylinders and calipers gently. Unfasten them and keep track of all the bolts and screws. Taking pictures can help you remember how things go back together.
Once the old parts are out, look at the brake drums or rotors to see if they're worn out. This is a good time to change or fix them so everything works well with the new brake system.
Install New Dual Circuit System
Start installing the new brake system by preparing all parts and keeping them organized.
Begin with the master cylinder. Pick one that fits the classic Ford model, paying attention to bore size and how it mounts. Compare tandem and split master cylinders. Tandem cylinders are safer because they separate the front and rear brakes, reducing the risk of total brake failure.
Attach the master cylinder to the firewall using a bracket made for the classic Ford. Make sure it aligns well.
Connect the brake lines to the master cylinder ports. Follow the manufacturer's guide for routing to avoid kinks and damage. Use good-quality fittings and tools to ensure no leaks.
Add a proportioning valve to balance the brake pressure between front and rear brakes. An adjustable valve can help you get the best braking performance.
Test and Adjust the Brakes
Before driving the classic Ford with its new brake system, check the brakes carefully.
First, make sure the brake pedal feels firm. If it feels soft, there might be air in the system, and it needs more bleeding. The pedal should move between 1 to 1.5 inches when pressed. If it moves more, adjust the brake linkage or the push rod.
Check the brake fluid level in the reservoir. It should match what the manufacturer recommends. If it's low, the brakes might not work well.
When the car is parked, press the brake pedal. It should stay firm and not sink, indicating no leaks.
Test the brakes while driving in a safe area. Go at a slow speed and press the brakes. The car should stop smoothly and not veer to one side.
If it does, check the brake balance. Make sure all wheels lock up at the same time during hard braking. This check ensures the brakes are evenly balanced.
People Also Ask
Can I Upgrade My Brake System Without Professional Assistance?
Yes, you can upgrade your brake system by yourself if you know a lot about fixing cars and have the right tools. But it's safer and often better to have a professional do it to make sure everything works correctly and safely.
What Are the Benefits of a Dual Circuit Brake System?
A dual circuit brake system makes cars safer by splitting the brakes into two separate parts. If one part stops working, the other part can still help the car stop. This means there's less chance of the brakes completely failing, keeping everyone safer.
How Long Does the Upgrade Process Typically Take?
Upgrading to a dual circuit brake system usually takes anywhere from a few hours to a whole day. How long it takes depends on how complicated the vehicle is, if all the parts are ready, and how skilled the person doing the upgrade is.
Are There Any Specific Brands Recommended for the New Brake Components?
For new brake parts, try brands like Wilwood, Brembo, and EBC. They are well-known for making good, strong brakes that work well and keep you safe. These brands are great for improving old cars with new, better brakes.
Is It Necessary to Modify the Brake Pedal Assembly for the Upgrade?
Sometimes, you might need to change the brake pedal parts to fit a new brake system in an old Ford car. It depends on the car's model and year. It's a good idea to ask a mechanic for help to be sure.
