PowerStop Z36 Front Brake Kit – Toyota 4Runner, FJ Cruiser & Tacoma | K137-36

Upgrade your Toyota truck or SUV's braking performance with the PowerStop Z36 Truck & Tow Front Brake Upgrade Kit, part #K137-36.

Designed specifically for trucks, SUVs, 4x4s, towing applications, and modified vehicles, the Z36 kit combines drilled and slotted performance rotors with PowerStop Z36 carbon-fiber ceramic brake pads to provide a complete, matched front brake upgrade.

This is an excellent choice for an FJ Cruiser, 4Runner, or Tacoma equipped with larger tires, suspension modifications, bumpers, winches, armor, overland equipment, or other accessories that increase vehicle weight and braking demands.

Complete Front Brake Upgrade

The PowerStop K137-36 provides the major components needed to upgrade the front brakes in one matched package.

Kit Includes:

• (2) Front drilled and slotted brake rotors

• (1) Complete set of Z36 carbon-fiber ceramic front brake pads

• Stainless-steel brake pad hardware

• High-temperature ceramic brake lubricant

One kit services the complete front axle.

Z36 Carbon-Fiber Ceramic Brake Pads

At the heart of the K137-36 kit are PowerStop's Z36 Truck & Tow carbon-fiber ceramic brake pads.

The Z36 compound is designed specifically for heavier trucks and SUVs and for vehicles subjected to increased braking demands from:

• Larger wheels and tires

• Towing

• Hauling

• Off-road driving

• Mountain driving

• Added vehicle weight

• Aftermarket bumpers and winches

• Skid plates and armor

• Overland and camping equipment

The carbon-fiber reinforced ceramic compound provides severe-duty braking capability while retaining the drivability needed for everyday street use.

Drilled & Slotted Performance Rotors

The K137-36 includes two drilled and slotted front brake rotors.

The drilled and slotted design helps manage the heat generated during repeated or demanding braking.

The rotor design also helps move water, gases, and debris away from the pad contact surface to promote more consistent braking performance.

Zinc-Plated Rotors

PowerStop applies a zinc-plated finish to the rotors to provide additional protection against rust and corrosion.

This is particularly beneficial on trucks and SUVs exposed to:

• Rain and moisture

• Mud

• Snow

• Road salt

• Off-road environments

• Changing weather conditions

The coating helps protect areas of the rotor that are not continually swept by the brake pads.

Built for Modified Trucks & SUVs

Adding larger tires and off-road accessories can substantially increase the amount of work required from your factory braking system.

Steel bumpers, winches, skid plates, rock sliders, roof racks, recovery equipment, larger wheels and tires, and camping equipment all add weight.

Larger-diameter tires can also increase the leverage the braking system must overcome when slowing the vehicle.

PowerStop specifically recommends the Z36 Truck & Tow compound when additional vehicle weight or larger wheel and tire combinations increase braking demands.

Excellent for Towing & Hauling

K137-36 is also an excellent choice for Toyota owners who tow or haul.

PowerStop engineered the Z36 system to handle the increased heat and braking demands associated with:

• Trailer towing

• Hauling cargo

• Mountain descents

• Repeated braking

• Heavier vehicle loads

This makes the kit especially useful for Tacomas, FJ Cruisers, and 4Runners that serve double duty as daily drivers and adventure, work, or tow vehicles.

Low-Dust Brake Compound

Despite its heavy-duty performance focus, the Z36 carbon-fiber ceramic compound is designed to minimize brake dust compared with many conventional friction materials.

PowerStop reports that its testing showed approximately 30% less brake dust on average compared with OE.

This helps provide a good balance between increased braking capability and everyday street manners.

Stainless-Steel Shims & Hardware

The Z36 brake pads use stainless-steel shims designed to withstand the elevated temperatures encountered in demanding truck and SUV applications.

The kit also includes stainless-steel installation hardware and high-temperature ceramic brake lubricant, helping provide the components needed for a proper installation.

Direct Bolt-On Upgrade

The PowerStop K137-36 is designed as a bolt-on replacement for the factory front brake components on compatible applications.

No brake-system modifications are required when installed on the correct vehicle application.

The kit retains the factory-style brake system while upgrading the friction material and rotor design.

319mm Front Rotors

K137-36 uses approximately 319mm (12.56-inch) diameter vented front brake rotors.

Because Toyota used multiple brake packages on some truck and SUV applications, rotor size and brake configuration should be verified before ordering.
