Power Stop Z36 Truck & Tow Rear Brake Kit – 2019–2021 Freightliner Sprinter 3500 | CPK8649-36

Power Stop’s Z36 Truck & Tow rear brake kit for the 2019–2021 Freightliner Sprinter 3500 — a complete rear brake package including coated rotors and Z36 carbon-fibre reinforced ceramic brake pads. Engineered for trucks, vans, and commercial vehicles that regularly tow, haul heavy loads, or carry significant cargo weight — applications where the additional vehicle mass generates more brake heat and demands more from the brake system than standard brake components are designed to handle. Covers the rear axle only — front kit sold separately.

Why the Z36 on a Sprinter 3500

The Freightliner Sprinter 3500 is the heavy-duty dual-rear-wheel variant of the Sprinter platform — widely used as a high-roof cargo van, camper van conversion base, and commercial work vehicle where regular operation at or near maximum payload capacity is the norm. At gross vehicle weight, the Sprinter 3500 places significantly more demand on the brake system than the standard 2500 variant — more mass requires more braking force and generates more heat, particularly during repeated stops in urban delivery or mountain driving with a loaded van. Standard OEM brake components are adequate for average driving conditions but are not optimised for sustained heavy-load use. The Z36 compound is specifically formulated for this operating environment: higher temperature tolerance, more aggressive bite under load, and better fade resistance than standard ceramic pads — maintaining consistent brake performance when the OEM pads would begin to overheat and fade.

Key Features

• Z36 Carbon-Fibre Reinforced Ceramic Pads: Power Stop’s Z36 compound uses carbon-fibre reinforcement in a ceramic matrix — providing higher temperature tolerance and fade resistance than standard ceramic pads. Engineered for towing, hauling, and heavy-load applications where sustained braking heat is the primary performance challenge. Low dust, low noise for daily commercial use
• Coated Rotors: Zinc-dichromate coating applied to the non-contact surfaces of the rotor (hat, vanes, and outer edge) — prevents the surface rust that typically appears on bare cast iron rotors within days of installation. The coating does not affect the braking surface, which beds in normally with the pads. Cleaner appearance and corrosion resistance for the life of the rotor
• Complete Rear Kit: Includes both rear rotors and rear pads — everything needed for a complete rear brake service in one part number. No need to source rotors and pads separately or verify compatibility between components
• Direct Fit: Engineered as a direct replacement for the 2019–2021 Sprinter 3500 rear brake components — uses the factory caliper, bracket, and hardware. No modification required
• Power Stop Engineering: Power Stop is a dedicated performance and heavy-duty brake specialist — the Z36 line is developed specifically for truck, van, and tow vehicle applications with real-world towing and hauling performance as the design target

What’s Included

• Rear coated rotors (pair)
• Z36 carbon-fibre ceramic rear brake pads (set)

Fitment

• Freightliner Sprinter 3500 (2019–2021)
• Mercedes-Benz Sprinter 3500 (2019–2021) — verify fitment for your specific market variant

Rear axle kit only — front brake kit sold separately. Verify your specific production date and trim level before ordering. A brake bed-in procedure is required after installation to properly seat the pads to the new rotors — follow Power Stop’s bed-in instructions to achieve full braking performance. Professional installation recommended.

Installation Note: A brake bed-in procedure is required after installing new rotors and pads. Do not skip the bed-in — properly bedded pads transfer an even layer of pad material onto the rotor surface, which is essential for achieving rated stopping performance and preventing brake judder. Follow Power Stop’s published bed-in procedure. Inspect brake callipers, caliper brackets, brake lines, and hardware at the time of installation and replace worn components as needed.
