Parts for your 2020 Toyota Rav4-Brake wheel cylinders

2020 Toyota RAV4 brake wheel cylinders — are they used?

Brake wheel cylinders aren’t fitted to the 2020 Toyota RAV4. Technical sources including Toyota’s 2020 RAV4 Repair Manual (XA50 platform) sections for Rear Disc Brake and Electronic Parking Brake, the Toyota Electronic Parts Catalogue (AXAA52/AXAH52/AXAL52 model codes), and Toyota Australia/New Zealand 2020 RAV4 specification guides all list four-wheel disc brakes with an electric parking brake across the range. Because wheel cylinders are specific to drum brake setups, they’re simply not present on this model.

Wheel cylinders live inside drum brakes and push the shoes outwards to create friction. The 2020 RAV4 instead uses floating disc brake calipers that squeeze brake pads against rotors. The move to discs brings better heat management, more consistent pedal feel, and straightforward integration with ABS, stability control and the electric parking brake (EPB). With no rear drum assemblies on Australian and New Zealand-delivered 2020 RAV4 variants, there’s no need—and no provision—for wheel cylinders.

What should be serviced instead? For routine brake work on a 2020 RAV4, the focus is on discs, calipers and the EPB system:

• Inspect and replace brake pads and rotors as required, check for taper wear, scoring and rotor thickness.
• Clean and lubricate caliper slider pins and pad abutments with high-temp brake grease.
• Manage the EPB correctly when doing rear pads: place the system in service/maintenance mode using a scan tool or the procedure in the Toyota repair manual before retracting pistons.
• Replace brake fluid at the interval in the owner’s manual (many workshops recommend every 24 months), using the fluid grade specified on the reservoir cap/manual.
• On hybrids, remember regenerative braking reduces pad wear in everyday driving, but the friction brakes still need periodic exercise and cleaning to avoid glazing and corrosion.

If a workshop is quoting wheel cylinders for a 2020 RAV4, that’s a red flag. The correct rear hydraulic component is a disc brake caliper with an integrated or attached EPB actuator, not a drum-type cylinder. Referencing Toyota’s repair and parts documentation will show no wheel cylinder part numbers for this model year and market.

Popular questions

Does a 2020 Toyota RAV4 have brake wheel cylinders?
No. The 2020 RAV4 runs disc brakes front and rear with an electric parking brake. Wheel cylinders are only used in drum brakes, which aren’t fitted to this model according to Toyota’s repair manuals, parts catalogue and AU/NZ spec sheets.

What should be serviced if there are no wheel cylinders?
Focus on pads, rotors and calipers. Clean and lube slider pins, check pad thickness and rotor condition, and manage the EPB in service mode before retracting rear pistons. Replace brake fluid at the recommended interval and inspect hoses, lines and ABS wiring during each service.

Why do some cars still use wheel cylinders while the RAV4 doesn’t?
Smaller or budget models may use rear drum brakes with wheel cylinders for cost and packaging reasons. The 2020 RAV4 benefits from four-wheel discs for stronger, more consistent braking and seamless integration with modern driver assists and the EPB, which suits SUV duty and towing better.
