Four-piston dust-sealed AERO4 calipers use BP-20 pads and 14.25 × 1.10-inch one-piece iron rotors with integral parking hats. Retain the original parking-brake mechanism. Rear hose kit 220-15680 is included; minor adjustment to the original hard line may be necessary for a safe connection. Check the six-on-5.50-inch interface, caliper alignment and original parking equipment. Use the wheel drawing with the nominal 18-inch minimum guidance rather than assuming every wheel of that diameter clears. The current vehicle listing specifies Japan, Near East and Africa-market Patrol Y61 applications; verify the actual regional hub and brake configuration.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-15597\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1326.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eContact PMB Performance with the brake-kit identification and measurements for help selecting the part.
