This is an ABS (Automotive Brake Solutions) aftermarket replacement piston engineered to meet OEM-quality standards for the lower piston position in the front Akebono Sport Brake Calipers found on select Nissan and Infiniti performance models. Designed for precise fitment and smooth hydraulic performance, this piston restores proper sealing and reliable braking operation in the lower front caliper chamber.

Product Details

The Akebono Sport brake package uses two different piston sizes in the front calipers:

• Upper Front / Rear Pistons (larger – sold separately)
• Lower Front Pistons (smaller – this part)

Over time, pistons can develop pitting, corrosion, or wear that weakens the fluid seal and causes sticking pistons, uneven pad wear, and reduced braking performance. This ABS-brand piston is manufactured to OEM-equivalent specifications and provides a cost-effective, high-quality solution for rebuilding the lower front chamber of your Akebono caliper.

Features

• ABS aftermarket component built to OEM standards
• Direct-fit replacement for the lower front piston location
• Precisely machined for proper diameter, length, and sealing surface
• Ensures smooth piston movement and dependable hydraulic sealing
• Helps resolve sticking pistons, uneven pad wear, and brake drag
• Ideal for Akebono Sport caliper rebuilds or maintenance
• Sold individually

Fitment Notes

• Fits the lower piston position in the front Akebono Sport Brake Caliper
• Does NOT fit upper front or rear piston positions (different size)
• Compatible with vehicles equipped with the factory Akebono Sport Brake Package
• Not for use with standard (non-Akebono) calipers

Installation / Recommended Parts

• Inspect caliper bores, seals, and dust boots during disassembly
• Recommended to pair with a new seal and dust boot kit for optimal results
• After reassembly, bleed the brake system and verify proper piston movement
• Ensure even pad contact and smooth piston retraction
• Rebuilding both front calipers at the same time is advised

ABS provides an OEM-standard solution for restoring full braking performance at a more cost-effective price point. This lower front piston helps ensure your Akebono Sport brake system delivers smooth, consistent stopping power.
