47731-0k060 Piston, brake caliper Fits Toyota Hilux

Product Function Description

The front disc brake piston is a critical hydraulic component within your Toyota vehicle‘s brake caliper assembly. This piston is the moving part that transfers hydraulic pressure from the brake fluid into mechanical force, pushing the brake pads against the brake rotor when you press the brake pedal. When brake fluid is pressurized, it acts against the back of the piston, forcing it outward to apply the brakes. For Toyota vehicles, a properly functioning brake piston ensures consistent brake pad pressure, even pad wear, and reliable stopping power. This piston is manufactured to exact dimensional specifications, ensuring proper fit within the caliper bore and reliable sealing performance.

When Should You Replace It?

Consider replacing your brake piston if you experience any of the following symptoms: Brake fluid leaks visible from the caliper area. Sticking or seized brake caliper causing the vehicle to pull to one side. Brake pads wearing unevenly or excessively on one side of the vehicle. Spongy or soft brake pedal feel that does not improve after bleeding. Visible corrosion, pitting, or scoring on the piston surface. The piston is damaged, bent, or cracked. Excessive brake dust or heat marks on one wheel. You are rebuilding the brake caliper – pistons should be replaced as part of a complete caliper rebuild. The rubber piston seal is damaged or leaking. Reduced braking performance on one wheel compared to the others. Note: Brake pistons should be inspected during brake service and replaced if signs of damage, corrosion, or wear are present.

Why Choose This Brake Piston?

Factory Specification Quality – This brake piston is manufactured to the exact dimensional and material standards of the original caliper component, ensuring proper fit within the caliper bore and reliable hydraulic performance.

Restores Caliper Function – Corroded or damaged pistons can cause caliper sticking, uneven pad wear, and reduced braking performance. This new piston restores proper caliper operation and braking efficiency.

Corrosion-Resistant Design – Manufactured with high-quality steel and corrosion-resistant surface treatment, this piston is designed to withstand exposure to brake fluid, moisture, and road salt without seizing or pitting.

Essential for Caliper Rebuilding – When rebuilding brake calipers, replacing the piston ensures that the caliper operates like new, with smooth piston movement and proper seal compression.

Prevents Uneven Pad Wear – A smooth, undamaged piston surface ensures even pressure distribution across the brake pad, preventing premature or uneven pad wear.

Restores Brake Feel – A new piston with a smooth surface and proper sealing helps restore firm, consistent brake pedal feel and reliable stopping power.

Proper Fit – Precision-engineered to match the original piston dimensions, ensuring correct clearance and seal compression within the caliper.

Package Contents

1 x Front Disc Brake Piston (47731-0K060). Note: Piston seals, dust boots, and brake caliper are NOT included. Please order seals and boots separately if rebuilding calipers. Brake pads and rotors are NOT included. Please confirm compatibility with your Toyota model before purchasing.

Common Issues with Brake Pistons

Toyota vehicle owners sometimes encounter brake piston issues: Corrosion – Exposure to moisture and road salt can cause corrosion on the piston surface, leading to seal damage, sticking, and fluid leaks. Pitting – Surface pitting damages the seal surface and allows fluid to bypass, reducing braking effectiveness. Seal damage – Worn or damaged seals allow fluid leaks and allow contaminants to enter the caliper bore. Heat damage – Repeated hard braking can cause heat-related damage to the piston and seals. Age-related wear – Over time, piston surfaces wear and seals degrade, reducing braking performance. This replacement piston is designed to address these issues with quality materials and corrosion-resistant surface treatment, restoring proper caliper function and reliable braking performance.
