Bosch QuietCast front disc brake rotor for Toyota 4Runner/FJ Cruiser/Tacoma — Front, Al/Zn coated, precision balanced

Bosch QuietCast Premium front disc brake rotor engineered to deliver balanced braking, reduced vibration, and corrosion resistance for Toyota 4Runner (2003–2009), FJ Cruiser (2007–2014), and Tacoma (2005–2016).

These Bosch QuietCast rotors combine OE-inspired engineering with aftermarket durability. Built with precision balancing, OEM-style vane design, and an aluminum/zinc anti-corrosion finish, they’re intended to replace worn factory rotors while maintaining original handling and braking feel. Each rotor includes Bosch’s engraved minimum thickness marking and, where applicable, an OEM-style ABS tone ring to preserve vehicle system compatibility.

How does this rotor improve brake feel and reduce pedal pulsation?

The rotor is factory mill precision balanced so weight is distributed evenly across the disc, which minimizes runout and reduces pedal pulsation during braking. A balanced rotor supports smoother stops, less vibration transmitted through the pedal, and a more consistent braking response under repeated use.

• Factory mill precision balancing for even mass distribution
• OEM-style vane configuration for stable thermal behavior
• Reduced vibration for a firmer, consistent pedal feel

Will these rotors resist rust and keep a clean appearance?

Bosch QuietCast rotors feature an aluminum/zinc clear-look coating that helps delay surface corrosion while preserving the rotor’s finished appearance—especially important for vehicles with exposed wheels. The finish is cosmetic and protective, helping the rotor look better for longer while standard brake wear still occurs.

• Aluminum/zinc coating to slow rust formation
• Clear-look finish suited to open-wheel designs
• Maintenance-friendly surface that complements alloy wheels

Are these rotors compatible with ABS and traction control systems?

On applications that require it, Bosch supplies an OEM-style ABS tone ring integrated with the rotor to ensure reliable wheel speed signals for ABS and traction control systems. That means the rotor maintains electronic system functionality without needing additional adapters or sensors.

• OEM-style ABS tone ring included where required
• Plug-and-play fitment for original electronic systems
• Preserves factory braking system operation and diagnostics

What inspection and end-of-life information is provided on the rotor?

Each Bosch QuietCast rotor has an engraved discard thickness marked on the part so installers and owners can tell when it’s time for replacement. The rotor is also engraved with the Bosch name and code to verify authenticity and facilitate correct identification during maintenance.

• Engraved minimum thickness (discard) marking for safety checks
• On-the-part Bosch branding and code for easy identification
• Supports straightforward service intervals and inspections

Who is this rotor for: Drivers and professional technicians seeking a reliable, OEM-style front rotor replacement for Toyota 4Runner (2003–2009), Toyota FJ Cruiser (2007–2014), or Toyota Tacoma (2005–2016). It’s suited to owners who want a rotor that matches factory performance, resists surface corrosion, and keeps ABS/traction systems working as intended. Recommended for routine replacement when restoring braking performance, reducing vibration, or refreshing the vehicle’s braking hardware during servicing.
