Frequently Asked Questions
What is the Power Stop BKC4539-26?
The Power Stop BKC4539-26 is a complete Z26 Street Warrior front brake kit with calipers for the 1993-1996 Cadillac Fleetwood, 1994-1996 Buick Roadmaster, 1994-1996 Chevrolet Caprice, and 1994-1996 Chevrolet Impala. The PSBKC4539-26 includes drilled and slotted front rotors, Z26 carbon-fiber ceramic pads, and powder-coated replacement calipers in one box.
What vehicles does the Power Stop BKC4539-26 fit?
The PSBKC4539-26 fits the 1993-1996 Cadillac Fleetwood, 1994-1996 Buick Roadmaster, 1994-1996 Chevrolet Caprice Classic, and 1994-1996 Chevrolet Impala SS. These vehicles share the same front brake rotor diameter and caliper dimensions on their rear-wheel-drive B-body and D-body platform, allowing one kit to cover multiple makes and models. Always verify your vehicle's specific brake rotor diameter and caliper bore against Power Stop's fitment guide.
Does the Power Stop BKC4539-26 include calipers?
Yes. The BKC4539-26 includes powder-coated replacement front calipers along with the drilled and slotted rotors and Z26 ceramic pads. This makes it a complete front brake kit requiring no additional caliper sourcing.
What is the Z26 Street Warrior compound?
The Power Stop Z26 Street Warrior is a carbon-fiber ceramic brake pad compound designed for street performance use. It offers better initial bite and higher fade resistance than standard OEM pads while maintaining low dust output and quiet operation under normal street driving conditions. The Z26 formula is appropriate for performance street driving, spirited driving, or heavy vehicles like the full-size sedans and wagons this kit fits.
Do the BKC4539-26 rotors need to be bedded in after installation?
Yes. Power Stop recommends performing a bedding procedure after installing the BKC4539-26. Make approximately 8 to 10 moderate deceleration stops from 30 to 40 mph with adequate cooling time between stops. Avoid hard stops during the first 200 miles to allow the pads to fully seat against the rotor friction surface and deposit an even transfer layer.
Will the BKC4539-26 improve stopping distance on the Cadillac Fleetwood?
The Power Stop BKC4539-26 is designed to provide improved heat management and more consistent brake pedal feel compared to worn OEM equipment. The drilled and slotted rotors reduce gas and debris buildup between pad and rotor during normal braking. Stopping distance improvements depend on the condition of the original brakes being replaced, but upgrading from worn OEM pads and rotors to new Z26 ceramic equipment typically restores or improves stopping performance.
Is brake fluid bleeding required after installing the BKC4539-26?
Yes. Replacing the front calipers requires bleeding the front brake circuit to remove any air introduced during the caliper swap. Use DOT 3 or DOT 4 brake fluid as specified in the Cadillac, Buick, or Chevrolet owner's manual for your specific vehicle. A complete brake bleed is recommended even if the new calipers are pre-filled.
Does the BKC4539-26 kit fit both sedan and wagon body styles of the Cadillac Fleetwood?
The Power Stop fitment for BKC4539-26 covers the 1993-1996 Cadillac Fleetwood, which includes both the front-wheel-drive Fleetwood Brougham and the rear-wheel-drive Fleetwood. The kit is designed for the rear-wheel-drive B-body Fleetwood platform. Confirm your specific Fleetwood configuration before ordering, as drivetrain and front brake dimensions differ between FWD and RWD Fleetwood variants.
