Parts for your 2016 Toyota Rav4-Brake wheel cylinders

2016 Toyota RAV4 brake wheel cylinders — are they used?

For the 2016 Toyota RAV4 (XA40 series — common AU/NZ variants include ZSA42R, ASA42R, ASA44R), brake wheel cylinders aren’t fitted. Wheel cylinders are a hydraulic component used in drum brake systems. The 2016 RAV4 runs four-wheel disc brakes — ventilated discs up front and solid discs at the rear — which use caliper pistons instead of wheel cylinders.

On this model, the service brakes are hydraulic disc brakes at all four corners, each with a floating caliper and a piston in the caliper to clamp the pads onto the rotor. That’s why a “brake wheel cylinder” part simply doesn’t exist on this vehicle’s service brake setup. The parking brake is a mechanical drum-in-disc (drum-in-hat) arrangement inside the rear rotors, operated by a cable, it uses small brake shoes and hardware, but no hydraulics and therefore no wheel cylinder either.

So if someone’s hunting a “wheel cylinder” for a 2016 RAV4, what they actually need will be one of the following, depending on the job:

• Rear brake caliper assembly or caliper service parts (piston, seals, slide pins, boots)
• Rear brake pads and rotors
• Parking brake shoes and fitting kit (springs/clips) for the drum-in-disc handbrake
• Brake hoses/lines or ABS actuator parts if chasing hydraulic issues

Technical sources that support this:

• Toyota Australia RAV4 2016 Specification/Data sheets — list ventilated front discs and solid rear discs across grades.
• Toyota New Car Features (NCF) for XA40 RAV4 — describes four-wheel disc brakes with 1-piston floating calipers and a cable-operated drum-in-disc parking brake.
• Toyota Repair Manual (Brake section, “Front Disc Brake”, “Rear Disc Brake”, and “Parking Brake [Drum-in-Disc]”) — procedures and parts shown are calipers, pads, rotors, and mechanical parking brake shoes, no wheel cylinders.
• Toyota Electronic Parts Catalogue (EPC) for 2016 RAV4 — rear brake listings show caliper assemblies, there are no wheel cylinder part numbers for this model year.

Bottom line: the 2016 RAV4 doesn’t use brake wheel cylinders. If the rear brakes are binding, pulsing or leaking, the fix will involve the rear calipers, pads, rotors, or the parking brake shoe hardware — not a wheel cylinder.

Popular questions

Do any 2016 RAV4 models in Australia or New Zealand have rear drum brakes?

No. For AU/NZ-delivered 2016 RAV4, all grades are equipped with rear disc brakes. The handbrake uses a small drum-in-disc mechanism, but that’s purely mechanical and has no hydraulic wheel cylinder.

What should be ordered instead of a wheel cylinder for a 2016 RAV4 rear brake repair?

Order the rear brake caliper (or a caliper seal kit and slide pin kit if rebuilding), plus pads and rotors as needed. If the issue is with the handbrake holding poorly or dragging, look at the parking brake shoes and fitting kit inside the rear rotor hat.

How can someone tell what the RAV4 has at the back — disc or drum?

Look through the rear wheel: a visible rotor (flat shiny disc) with a caliper confirms disc brakes. The small parking brake “drum” is hidden inside the hat of that rotor, so you won’t see a conventional drum backing plate like you would on a drum-brake axle.
