Brembo UV Coated OE Front Brake Rotor 4WD (1986-95 4Runner)

Brembo UV Coated OE Front Brake Rotors 4WD For 1986–1995 Toyota 4Runner 4WD Overview The Brembo Prime UV Coated Front Brake Rotor is an OE-equivalent replacement for 1986–1995 Toyota 4Runner 4WD front brake applications. This listing covers two production-specific rotor configurations: a 289 × 20 mm vented rotor through 05/1991 and a 291 × 25 mm vented rotor from 06/1991 through 1995. Both configurations use a 100 mm centering diameter and six-hole mounting design. Because the change occurs during the 1991 model year, owners of 1991 4Runners should verify the vehicle's production date before ordering. When the production date is uncertain, the existing rotor diameter and thickness can also help identify the correct configuration.
