Street Warrior Z26 Performance Brake Upgrade for the 1971-1973 Buick Centurion Front Axle
The PSBK4539-26 is the PowerStop Z26 Street Warrior Brake Upgrade Kit for the front axle of the 1971, 1972, and 1973 Buick Centurion. PowerStop designed the Z26 specifically for muscle cars and high-performance vehicles, combining drilled-and-slotted zinc-plated rotors with carbon-fiber ceramic brake pads in a single kit that delivers everything needed for a front brake system upgrade.
The PSBK4539-26 is engineered for street-driven Centurions and those used at high-performance and car show events where stopping power and brake appearance matter. The drilled holes promote cooling airflow and reduce moisture fade, while the slots continuously clean the pad face for consistent bite. The carbon-fiber ceramic compound is engineered for high-horsepower and high-torque applications. The PSBK4539-26 includes stainless-steel shims, new pin bushing kit where applicable, and premium lubricant, making it a complete front brake service for the Centurion platform.

Frequently Asked Questions
What is the PSBK4539-26?
The PSBK4539-26 is the PowerStop Z26 Street Warrior Front Brake Kit for the 1971-1973 Buick Centurion. It includes drilled, slotted, and zinc-plated front rotors and Z26 Carbon-Fiber Ceramic brake pads, plus all hardware and lubricant needed for a complete front brake upgrade on the Centurion platform.
What years does PSBK4539-26 fit?
The PSBK4539-26 is specifically engineered to fit the 1971, 1972, and 1973 Buick Centurion front brake application. Verify fitment with PowerStop's application guide if you are using a modified or aftermarket spindle or front end conversion.
Is the Z26 kit on PSBK4539-26 suitable for street driving?
Yes. The PSBK4539-26 is designed for high-performance street use. The Z26 carbon-fiber ceramic compound does not require warm-up for normal street stops and produces significantly less dust than competing performance compounds, making it suitable for daily-driven and show muscle car applications.
Do the rotors on PSBK4539-26 rust?
The rotors are zinc-plated to resist corrosion on non-contact surfaces. The swept face of the rotor will show slight surface rust between drives, which is normal and clears after the first brake application. The zinc coating on the hat, vane, and outer edge protects those areas and maintains a clean appearance.
Do I need to do a break-in procedure with PSBK4539-26?
Yes. PowerStop recommends a bedding procedure: perform 5 moderate to aggressive stops from 40 mph to 10 mph, then 5 moderate stops from 35 mph to 5 mph, then allow the brakes to cool. This transfers an even layer of pad material to the rotor and helps prevent judder. Detailed instructions are included in the kit.
Can PSBK4539-26 be used on a track?
The Z26 is engineered for street and occasional performance driving. For dedicated track or autocross use, PowerStop offers the Z32 Carbon-Ceramic and Z36 Truck and Tow series. PSBK4539-26 will perform well on the street but may fade under repeated sustained track-speed braking.
Does PSBK4539-26 fit the 1971-1973 Buick Centurion convertible?
Yes. All body styles of the 1971-1973 Buick Centurion share the same front brake platform, so the PSBK4539-26 applies to coupe and convertible variants.
What is the warranty on PSBK4539-26?
PowerStop provides a limited warranty on the PSBK4539-26. Contact PowerStop customer service with your order information and a description of the issue to initiate a warranty claim.
