To upgrade from drum to disc brakes on a classic Nissan, start by assessing your current system, checking for compatibility with disc brakes. Choose a disc brake kit tailored to your model and driving habits. Consider rotor materials like cast iron or cross-drilled steel and caliper types for enhanced performance. Gather essential tools: socket set, brake fluid, and safety gear. Disconnect the battery and elevate the car on jack stands. Carefully remove the old brakes, install new components, and check for correctness. After installation, test the new brakes thoroughly for alignment and firmness. Further insights await as you progress through each step.
Assessing Your Current Braking System
Before you switch your classic Nissan's drum brakes to disc brakes, check your current braking system. Look at parts like brake lines, the master cylinder, and wheel hubs. See if these parts can work with disc brakes or if you need new ones. Think about the car's age and how worn these parts might be.
Check how your current brakes work. Drum brakes and disc brakes stop differently. This can change how your car feels when you brake. Feel the brake pedal and note the stopping distance to know how your brakes perform now. This helps you know what changes to expect with the new brakes.
Also, look at how weight is spread in the car and how the suspension is set up. These can change how well brakes work. Classic Nissans with rear drum brakes might need changes in the rear axle and suspension for the new brakes to fit. Understanding these can make the upgrade process smoother.
Selecting the Right Disc Brake Kit
When upgrading your classic Nissan's brakes, picking the right disc brake kit is key for top performance and fit. A good kit boosts stopping power and safety, making your drive smoother. Think about your Nissan's model and year, as design changes can affect fit. Also, consider how you'll drive—daily trips or racing. Different kits suit different needs.
Here's a quick look at important features:
| Feature | Option A: Standard Kit | Option B: Performance Kit |
|---|---|---|
| Rotor Material | Cast Iron | Cross-Drilled Steel |
| Caliper Type | Single Piston | Multi-Piston |
| Brake Pad Type | Organic | Semi-Metallic |
| Best For | Street Use | Track and Street Use |
When choosing, look at rotor material and caliper type. These affect how long parts last and how well they cool. Brake pad type changes noise and dust levels. Match these features to what you need so your Nissan's brakes work just right.
Gathering Necessary Tools and Materials
Before you start changing your classic Nissan's drum brakes to disc brakes, gather all the tools and materials you'll need. This will help make the job easier and prevent problems later.
Here's what you'll need:
- Tools: Get a good socket set, wrenches, and pliers to handle different bolts and fittings. A sturdy jack and jack stands will keep your car stable and safe while you're working underneath.
- Brake Fluid: Choose the right brake fluid for your Nissan to ensure it works well after the upgrade.
- Additional Materials: You'll need brake cleaner to remove grease and grime from new parts. Thread lock keeps bolts secure. Check your brake calipers and rotors for any damage from shipping. Anti-seize lubricant can stop rust and make future maintenance easier.
- Safety Gear: Wear gloves and eye protection to stay safe from harmful substances and debris.
- Torque Wrench: Use this to make sure bolts are tightened correctly, which prevents them from wearing out or failing too soon.
Preparing Your Nissan for Installation
Gather your tools and materials, then get your classic Nissan ready for the installation. Start by setting up a tidy and open workspace. Park the car on a flat surface and lift it with jack stands. This keeps the car stable and gives you room to work underneath. Unplug the battery to avoid any electrical issues. Take off the wheels for easy access to the brake system.
Before moving on, check the current brake setup for any wear or damage. This helps you spot any problems and see the differences between drum and disc brakes. Clean the wheel hubs and nearby parts to make the installation go smoothly.
Look at the car's manual for any special steps. The manual also tells you the right torque settings and safety tips.
| Task | What to Do |
|---|---|
| Set Up the Car | Elevate it with jack stands |
| Unplug the Battery | Stops electrical problems |
| Check Brakes | Look for damage and clean parts |
Having all parts and tools ready makes moving from prep to installation easy. This sets you up for a successful brake upgrade.
Installing Front Disc Brakes
Start by gathering all your tools and brake parts.
First, take off the wheel and the old drum brake. Remove the backing plate too. This will make room for the new disc brakes.
Next, put the disc brake bracket on the spindle. Make sure it fits tightly.
Then, place the rotor on the hub, and line it up with the wheel studs. Use a lug nut to hold it in place for now.
Now, attach the caliper bracket and caliper. Slide the brake pads into their spots. Make sure everything lines up right to prevent uneven wear.
Here's what you need to do:
- Take off the wheel and drum.
- Remove the backing plate.
- Put on the disc brake bracket.
- Place and hold the rotor.
- Attach the caliper and add the brake pads.
Testing and Adjusting the New Brakes
Once the new disc brakes are on, it's time to check and tweak them for top-notch performance and safety. Start by looking over all the parts closely. Make sure the calipers, rotors, and pads are lined up right and tightly fastened. Press the brake pedal while the car is still to check its firmness. If it feels soft, there might be air in the system, and you'll need to bleed the brakes.
Take the car for a test drive in a safe spot. Slowly speed up and then use the brakes to see how they work. Pay attention to any strange noises and how long it takes to stop. If the car pulls to one side when braking, you may need to adjust the calipers or check the brake lines.
Here's a simple guide for common brake problems and fixes:
| Problem | Cause | Fix |
|---|---|---|
| Soft pedal | Air in lines | Bleed the brakes |
| Squeaky brakes | Dirty pads | Clean or change the pads |
| Pulling to side | Uneven pressure | Adjust the calipers |
| Vibrations | Bent rotors | Resurface or change the rotors |
