Power Stop K5577-36 Z36 Truck & Tow Brake Kit: Superior Stopping Power for Your Ford Expedition or Lincoln Navigator

Your Ford Expedition or Lincoln Navigator is a capable vehicle, built for more than just grocery runs. Whether you’re towing a boat, hauling a camper, navigating challenging off-road terrain, or simply loading up for a family road trip, you’re placing significant demands on your braking system. Standard brakes are designed for average use, but when you push your vehicle to its limits, you need a brake system that can keep up. It’s not just about stopping; it’s about controlled, consistent, and reliable stopping power, even under pressure.

A Day at the Lake (Scenario):

Imagine this: You’re heading to the lake for a weekend getaway. Your Ford Expedition is fully loaded with gear, and you’re towing your boat. As you descend a long, winding mountain road, you notice your brakes starting to feel a bit…spongy. The pedal travels further, and you have to press harder to get the same stopping power. This is brake fade, a potentially dangerous situation caused by excessive heat buildup in your braking system. It’s a clear sign that your stock brakes are struggling to cope with the increased load and demands.

Beyond “Stopping”: The Science of Braking

At its core, braking is about converting kinetic energy (the energy of motion) into thermal energy (heat). When you press the brake pedal, you’re initiating a chain reaction:

1. Hydraulic Pressure: Your foot’s pressure is amplified by the brake booster and transmitted through brake fluid, a specialized hydraulic fluid.
2. Caliper Squeeze: This pressure forces calipers to squeeze brake pads against the brake rotors (also known as discs).
3. Friction: The friction between the pads and rotors generates the force that slows your vehicle.
4. Heat Dissipation: This friction also generates a significant amount of heat. This heat needs to be dissipated efficiently to maintain braking performance.

Friction and Heat: The Dynamic Duo

Friction is the key to stopping, but it’s also the source of heat. The amount of heat generated depends on several factors, including the vehicle’s weight, speed, and the braking force applied. The higher these factors, the more heat is generated. The materials used in your brake pads and rotors play a critical role in how well they handle this heat.

Enter the Power Stop K5577-36: Designed for Performance

The Power Stop K5577-36 Z36 Truck & Tow Brake Kit is specifically engineered to address the challenges of heavy loads, towing, and demanding driving conditions. It’s a complete upgrade, designed as a direct bolt-on replacement for the stock brakes on 2010-2017 Ford Expedition and Lincoln Navigator models (with 6-lug wheels). But it’s not just a replacement; it’s a significant enhancement.

Rotors: More Than Meets the Eye: Drilled, Slotted, and Zinc-Plated

The rotors in the K5577-36 kit are far from ordinary. They feature a combination of design elements that work together to improve braking performance:

• Drilled Holes: These precisely engineered holes aren’t just for show. They significantly increase the surface area of the rotor, allowing for more efficient heat dissipation. Think of it like adding extra fins to a radiator – more surface area means more heat can escape into the surrounding air.
• Slots: The curved slots machined into the rotor surface serve multiple purposes. First, they help to “wipe away” brake dust, water, and gases that can build up between the pad and rotor. This ensures consistent contact and prevents a “glazing” effect that can reduce braking power. Second, the slots provide additional pathways for hot air to escape.
• Zinc Plating: The silver zinc dichromate plating isn’t just for aesthetics (although it does look great behind your wheels!). It provides a crucial layer of protection against rust and corrosion. This is especially important in harsh environments where road salt and moisture can accelerate corrosion.

The Z36 Pads: Carbon-Fiber Ceramic Magic

The brake pads are the other half of the braking equation, and the Z36 pads in the Power Stop K5577-36 kit are a significant upgrade over standard brake pads. They’re formulated with a unique carbon-fiber ceramic compound. Here’s why that matters:

• Carbon Fiber Reinforcement: The addition of carbon fibers to the ceramic matrix significantly enhances the strength and thermal stability of the pads. Carbon fibers are incredibly strong and lightweight, and they can withstand extremely high temperatures. This means the pads are less likely to deform or break down under heavy braking.
• Ceramic Compound: Ceramic materials are excellent at dissipating heat and resisting fade. They also tend to produce less dust and noise than traditional metallic or semi-metallic brake pads.
• The Combination: The combination of carbon fiber and ceramic creates a brake pad that offers superior stopping power, excellent fade resistance, low dust, and quiet operation. It’s a winning formula for demanding applications.

Beyond the Components: Brake Fluid and the Hydraulic System

While the rotors and pads are the stars of the show, the brake fluid is the unsung hero of your braking system. It’s the hydraulic fluid that transmits the force from your foot on the pedal to the calipers.

Brake Fluid’s Critical Role

Brake fluid needs to have a high boiling point. Why? Because as your brakes heat up, the fluid heats up too. If the fluid boils, it creates vapor bubbles, which are compressible. This leads to a spongy brake pedal and reduced braking power – a dangerous situation.

Choosing the Right Fluid
There are mainly 2 types of brake fluids that will apply to this specific break kit, DOT 3,DOT4 and DOT 5.1.
DOT 3 and 4 are glycol-ether based. However, Dot 5.1 is a borate ester fluid with a higher boiling point and lower viscosity, making it suitable for high-performance vehicles and ABS systems.
It’s recommended to replace the brake fluid every two year.

Keeping Your Brakes in Top Shape: A Little Maintenance Goes a Long Way

Even the best brakes need occasional maintenance. Here are a few tips:

• Regular Inspections: Check your brake pads and rotors for wear and tear.
• Fluid Flushes: Replace your brake fluid according to the manufacturer’s recommendations.
• Proper Break-In: After installing new brakes, follow the recommended break-in procedure to ensure optimal performance.
