On the XA40 RAV4 this is one of the friendlier brake jobs out there. The front caliper comes off with two 14 mm guide-pin bolts, the bracket with two 17 mm bolts, and the rotor just slides off the hub - there are no retaining screws and no electronic parking brake to put in service mode. Budget most of your time for rust: the bracket bolts are torqued to about 79 ft-lb and the rotor often needs bolts threaded into its jack holes to break free of the hub.
The mistake people make is skipping the hub face. Any rust ridge left under the new rotor shows up as a pulsating pedal a few thousand miles later, and it gets blamed on cheap rotors. Wire-brush the hub down to bare metal, clean it, and check that the new rotor sits flat. Second most common mistake is greasing the guide pins with regular chassis grease - use silicone brake grease so it does not swell the rubber bushings, which is a classic cause of uneven pad wear on these.

North American XA40 RAV4s all use the 2.5L 2AR-FE, so front brake fastener sizes are identical across trims and years: 14 mm guide-pin bolts, 17 mm bracket bolts, 21 mm lug nuts. The 2016-2018 RAV4 Hybrid uses the same front caliper hardware and sizes, but has regenerative braking, so top off fluid and expect a different pedal feel during bedding. Non-US diesel and 2.0L versions of this generation share the 14 mm/17 mm arrangement but can use a smaller rotor diameter - measure before ordering.
| Caliper guide pin (slide) bolts, 14 mm head | 25 ft-lb (34 Nm) |
| Caliper bracket to steering knuckle bolts, 17 mm head | 79 ft-lb (107 Nm) |
| Wheel lug nuts | 76 ft-lb (103 Nm) |
| Brake hose bracket / union bolt (if disturbed) | verify in the service manual |
The 14 mm guide-pin bolts, 17 mm bracket bolts and 21 mm lug nuts are standard across the 2013-2018 XA40 with the 2AR-FE, and the torque figures match Toyota's front disc spec; confirm rotor size (most are 305 x 28 mm) and minimum thickness stamped on your own rotors before ordering.
The two caliper guide-pin (slide) bolts take a 14 mm socket, and the two caliper bracket bolts that hold the bracket to the steering knuckle take a 17 mm socket. Lug nuts are 21 mm.
The rotors are not bolted on - they float on the hub and are held by the wheel. Torque the bracket bolts to 79 ft-lb (107 Nm), guide-pin bolts to 25 ft-lb (34 Nm), and lug nuts to 76 ft-lb (103 Nm) in a star pattern.
The XA40 rotor has two M8 x 1.25 threaded jack holes in its face. Thread in two 50 mm bolts and tighten them alternately a half turn at a time and the rotor will press itself off. Penetrating oil around the hub center and a dead blow on the friction face also help.
No. The XA40 uses a conventional cable or foot parking brake on the rear, and nothing about the front calipers is electronically actuated. Just pump the pedal firm before driving and no reset is required.
