2003-2009 Toyota 4Runner Z36 Front Brake Kit Overview

Important fitment note: This kit only fits 2003-2009 (4th Gen) Toyota 4Runner trucks with 319 mm front rotors. Many Sport, Limited, and V8 trucks use 338 mm front rotors, and this kit will not fit those. Measure your front rotors, or call or text a Toyota brake expert at 850-324-6726 to confirm before you order.

This Power Stop Z36 Truck & Tow front brake kit is a bolt-on upgrade that stays at the stock 319 mm rotor size. It is not a big-brake kit. It replaces the front pads, rotors, and calipers with remanufactured red powder-coated 4-piston calipers, drilled and slotted zinc-plated rotors, and Z36 carbon-fiber ceramic pads.

Power Stop builds the Z36 Truck & Tow line for trucks that tow, haul extra weight, or see mountainous driving. This kit does not include brake hoses or brackets.

What's Included

• 2 remanufactured red powder-coated 4-piston front calipers
• 2 drilled, slotted, and zinc-plated front rotors (319 mm / stock size for this application)
• Z36 carbon-fiber ceramic front brake pads with stainless-steel shims
• Stainless-steel hardware and high-temp brake lubricant

Specs

• Calipers: remanufactured, red powder-coated, 4-piston (front)

• Pads: Power Stop Z36 carbon-fiber ceramic, with stainless-steel shims

• Not included: brake hoses and brackets
• Power Stop part number: KC137-36

Fitment

• Fits: 2003-2009 Toyota 4Runner (4th Gen) with 319 mm front rotors only
• Many Sport, Limited, and V8 trucks use 338 mm front rotors. This kit is not for those trucks.
• This is a stock-size kit for the 319 mm application, so wheels that clear the factory 319 mm rotors should still clear these rotors.

Complete Your Brake Upgrade

While the calipers are off, this is a good time to replace the factory rubber hoses with Brakeline Pros braided stainless brake lines for the 2003-2009 4Runner. Choose an extended length if your truck is lifted.

FAQ

How do I know if I have 319 mm or 338 mm front rotors?

Measure the diameter of your front rotors, or check your trim. Many Sport, Limited, and V8 4th Gen 4Runners use the larger 338 mm rotors. If you are not sure, call or text 850-324-6726 and we will help you confirm.

Is this a big-brake kit?

No. This is a stock-size bolt-on upgrade for trucks that already have 319 mm front rotors. If you want larger rotors and multi-piston calipers built as a big-brake kit, see our Performance Brake Kits.

Are brake lines included?

No. Hoses and brackets are not included. We recommend replacing the lines with our braided stainless lines while the calipers are off, and choosing an extended length if the truck is lifted.
