Toyota RAV4 Brake Fluid Guide

Brake fluid is a liquid chemical solution that helps support your car’s braking system. It amplifies your foot’s force on the pedal, so your car stops without the need for additional force.

However, brake fluid loses effectiveness over time and becomes dirty. To maintain a properly working vehicle, you must change the fluid according to the manufacturer’s recommendations.

This guide will explain all the basics that you’ll need to know about changing your RAV4’s brake fluid so you can be prepared and informed.

Fluid Type

All Toyota RAV4s, regardless of the model year, are compatible with the following brake fluid:

  • SAE J1703
  • FMVSS No. 116 DOT 3

Toyota RAV4s manufactured from 2019 to 2024 are also compatible with

  • SAE J1704
  • FMVSS No. 116 DOT 4.

The primary difference between DOT 3 and DOT 4 brake fluid is water absorption. DOT 3 brake fluid absorbs less water from the air than DOT 4.

This means that you must change DOT 3 brake fluid less often. However, DOT 4 has its own benefits. It has a higher dry and wet boiling point, which makes it safer for higher temperatures (

You shouldn’t mix different types of Toyota RAV4 brake fluid as this can cause brake malfunction. Stick to the types listed above and reach out to a professional if you’re unsure about what to select for your car.

Change Frequency

As noted above, changing your brake fluid at the right time is critical to maintaining a properly functioning vehicle. Here’s how to know when you should change your brake fluid.

Toyota recommends inspecting the brake fluid every 6 months years or 5,000 miles. If the fluid is low, it should be topped off. If the fluid is severely discolored, it should be flushed and fully replaced.

Similar to your motor or engine oil, the brake fluid will change color as it’s used. Fresh brake fluid is almost clear or transparent with a hint of yellow. Over time, it becomes dark brown or black, and this is how you know it’s time for a brake fluid flush and replacement.

Remember, failing to change your brake fluid can result in “soft” brakes as well as other issues. Soft brakes are when a brake pedal no longer offers the same reassuring pressure it typically does. This can be alarming to drivers, and it’s not something you want to encounter if you can avoid it.

How to Check the Fluid Level

  1. Pop your hood and head over to the driver’s side
  2. Find the Toyota RAV4 brake fluid reservoir
  3. Look at where the level falls on the outside of the container (this is easier to see if the fluid is dirty)

If you don’t see the fluid level while looking at the reservoir, this could be that the fluid is very low or the reservoir is dirty on the outside.

Take a damp cloth and wipe down the exterior of the reservoir thoroughly. This should make it easier to view the fluid level.
