Choosing the Best Aftermarket Disc Brake Pads for Your 1970 Buick Wildcat
Modernize the stopping power of your classic 1970 Wildcat with the right set of new aftermarket brake pads.
- Modern ceramic or semi-metallic aftermarket pads are a significant safety and performance upgrade over the Wildcat's original 1970s organic pads.
- Choose a pad material based on your driving style: ceramic for quiet cruising or semi-metallic for more aggressive stopping power.
- When replacing pads, always inspect the calipers, rubber brake hoses, and rotors for age-related wear or failure.
- For best results, always install new pads with new or freshly resurfaced brake rotors.
Symptoms of Worn-Out Brake Pads
Worn brake pads can't create the friction needed to stop your heavy Wildcat safely. Listen and feel for these warning signs:
- Squealing or Screeching: A high-pitched noise when you apply the brakes, often caused by a built-in wear indicator.
- Grinding Noises: A loud, harsh grinding or growling means the pads are completely worn away, and metal is grinding against metal. This is a critical safety issue that damages brake rotors.
- Increased Stopping Distance: If you notice the car takes longer to stop than it used to, your pads are likely worn and have lost their effectiveness.
- Vibration or Pulsing: A pulsing sensation in the brake pedal can indicate worn pads or warped rotors.
Choosing the Right Aftermarket Brake Pads
Original brake pads from 1970 were made of organic materials. Modern aftermarket pads offer a significant upgrade in safety and performance. The choice comes down to your driving style and priorities.
Pad Material Types
- Ceramic: The best choice for most daily driven classic cars. Ceramic pads are very quiet, produce minimal, light-colored dust, and are gentle on your brake rotors. They provide consistent, reliable stopping power for normal driving. Brands like Centric, Bosch, and Wagner are well-regarded for their ceramic pads.
- Semi-Metallic: A great all-around performance option. These pads contain metal fibers that help dissipate heat and provide a stronger "bite" than ceramic pads. They offer improved stopping power, which is great for a heavy car like the Wildcat, but they tend to create more dust and may be slightly noisier than ceramics.
- Organic (Non-Asbestos): While this is what your car came with, modern organic pads are generally only used for concours restorations where originality is the top priority. They wear faster and are more susceptible to brake fade (losing stopping power when hot) than modern materials.
Pro Tip: A Pad for Every Purpose
For a 1970 Wildcat, you can't go wrong with a quality set of ceramic or semi-metallic pads. They will perform better and last longer than the original 1970s technology. Consider how you use your car: for quiet cruising, choose ceramic. For more spirited driving, a semi-metallic pad might give you the extra confidence you want.
Recommended Aftermarket Brands
Several reputable brands offer disc brake pads for your Wildcat. They can be grouped into tiers based on their intended use.
- Daily Driver (Good): These brands offer excellent quality and value for normal street use. They are often quieter and produce less dust.
- Centric (Posi-Quiet Ceramic): Highly recommended in forums for being quiet, reliable, and a great value.
- Wagner (ThermoQuiet): A top choice for technicians, known for quiet operation and quality construction.
- Bosch (QuietCast): A well-respected brand offering quality ceramic pads with good performance for daily driving.
- Performance Street (Better): For owners who want a bit more stopping power and have a more spirited driving style. These may be semi-metallic or hybrid formulas.
- PowerStop (Z23 Evolution): A popular upgrade kit that often includes drilled/slotted rotors. Known for increased stopping power but can sometimes be noisy.
- Raybestos (Element3 EHT): A hybrid pad that gets good reviews for offering strong bite with low dust, providing a good balance of performance and comfort.
- High Performance (Best): For those who prioritize braking performance above all else, and don't mind some potential for noise or dust.
- EBC Brakes (Greenstuff/Yellowstuff): Often mentioned as a top-tier performance pad for classic cars and spirited driving.
Inspect the Whole System
When replacing pads on a classic car, it's a perfect time to inspect the entire brake system. Common issues on older cars include seized caliper pistons, collapsed rubber brake hoses, and worn or rusted rotors. A new set of pads won't work correctly if other parts of the system are failing.

Frequently Asked Questions (FAQ)
What's the difference between ceramic and semi-metallic pads?
Ceramic pads are quieter, produce less dust, and are gentler on rotors, making them ideal for daily driving. Semi-metallic pads offer better high-heat performance and a stronger initial bite, which is good for heavy vehicles and spirited driving, but they can be dustier and noisier.
Do I need to replace my brake rotors at the same time?
It is highly recommended. Installing new pads on old, worn, or grooved rotors will reduce the effectiveness of the new pads and cause them to wear out unevenly and prematurely. For best performance and safety, always install new pads and rotors together.
What is "bedding-in" new brake pads?
Bedding-in is a process of several controlled stops to properly transfer a thin, even layer of friction material from the new pads onto the rotors. This process ensures smooth, quiet, and powerful braking. Most manufacturers provide specific instructions, but it typically involves a series of moderate stops from around 40-50 mph without coming to a complete stop.
Are expensive performance pads worth it for my Wildcat?
It depends on your driving style. For regular cruising and street driving, a quality daily-driver ceramic or semi-metallic pad from a brand like Centric or Wagner is more than sufficient and will be a huge upgrade over the original pads. High-performance pads from a brand like EBC are only necessary if you engage in very aggressive street driving or autocross events.
