Stoptech 127.44109R Disc Brake Rotor - Front Right

StopTech Front Right Brake Rotor for Tacoma and 4Runner

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor, part number 127.44109R, is a direct replacement front right rotor for select Toyota Tacoma and Toyota 4Runner applications. It combines a vented rotor design with cross-drilled and slotted surfaces to improve heat management, pad bite, and braking consistency in wet and dry conditions.

Key Features

• Direct replacement disc brake rotor for factory brake systems and stock calipers
• Slotted X drilled surface helps disperse heat and brake dust
• Cross-drilling helps reduce pad glazing and improve initial bite
• Black e-coating helps protect exposed surfaces from corrosion
• High carbon metallurgy in most applications supports quieter operation and improved crack resistance
• Vented rotor construction with straight vanes
• Coated hat finish for added durability

Product Details

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are built as 1-piece replacement brake discs for vehicles using factory brake hardware. This rotor measures 296.8 mm outside diameter, 21.7 mm nominal thickness, 20.0 mm discard thickness, and 70.5 mm overall height, with a 108.0 mm center hole diameter and 139.7 mm bolt circle diameter. The floating disc mounting and 6-lug pattern match the listed Toyota fitments, including 2004 Toyota Tacoma front right, 1998-2003 Toyota Tacoma front right, 1995-1998 Toyota Tacoma front right, 1997-2002 Toyota 4Runner front right, and 1995-1996 Toyota 4Runner front right. This part number 127.44109R is a practical choice for drivers searching for a Toyota Tacoma front right brake rotor or a Toyota 4Runner front right drilled and slotted rotor.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake fade from repeated stops and elevated rotor temperatures
• Uneven pad transfer that can lead to glazing
• Reduced wet-weather braking response
• Brake dust buildup on the rotor surface
• Corrosion on exposed rotor surfaces

Installation Notes

Install on the front right position only where the vehicle listing matches exactly. Verify rotor dimensions, 6-lug bolt pattern, and caliper casting notes before installation, especially on 1997-2002 Toyota 4Runner and 2004 Toyota Tacoma applications with listed exceptions. Use new pads and inspect caliper condition, hub surface cleanliness, and brake fluid condition during service. Follow factory torque specifications and bedding procedures after installation.

Quality Assurance

StopTech uses black e-coating for corrosion protection and high carbon metallurgy in most applications to support quieter operation and improved crack resistance. The rotor is engineered as a direct replacement for factory brake systems and stock calipers, with construction focused on consistent braking performance and long-term durability.
