Bleeding Toyota Brakes with ABS
Bleeding the brakes on a Toyota vehicle with ABS (Anti-lock Braking System) may require some additional steps compared to bleeding brakes on a non-ABS vehicle. Here are some steps you can follow to bleed Toyota brakes with ABS:
1. Prepare the necessary tools: You will need a brake bleeder tool, such as a Motive or Mityvac pressure bleeder, and a vacuum bleeder, like the Mityvac. These tools can help ensure a thorough brake fluid flush and remove any air bubbles from the system.
2. Start with a manual bleed: Begin by manually bleeding the rear right (RR), rear left (LR), front right (RF), and front left (LF) brakes. This is the initial step in the bleeding process.
3. Use a pressure bleeder: If there is still air in the ABS module, you can use a pressure bleeder system to force the air out. Connect the pressure bleeder to the brake fluid reservoir and push fluid over to the ABS block. Bleed about 16 ounces from each bleeder.
4. Try a vacuum bleeder: If the pressure bleeder doesn’t completely remove the air from the system, you can try using a vacuum bleeder. This tool can help draw out any remaining air bubbles from the brake lines.
5. Repeat the bleeding process: After using the pressure bleeder and vacuum bleeder, it is recommended to manually bleed the RR, LR, RF, and LF brakes again. This ensures that fresh fluid is drawn into the ABS unit and any remaining air is removed.
6. Verify pedal feel: After bleeding the brakes, it is important to confirm the pedal height and feel. If necessary, rebleed the brakes until the pedal feels firm and responsive.
It’s worth noting that bleeding ABS brakes can be a complex process, and it may be helpful to consult the vehicle’s specific service manual or seek assistance from a professional mechanic if you are unsure or uncomfortable performing the procedure yourself.
Remember to always follow proper safety precautions when working on your vehicle’s braking system, such as wearing protective eyewear and gloves, and ensuring the vehicle is securely supported.

How do you get air out of brake lines without bleeding?
To get air out of your brakes, you have to bleed them. There’s no two ways around it—to remove the air it has to be replaced with new fluid. That may seem easy enough (and it is, for an experienced mechanic) but doing any DIY on your brakes is dangerous.
How do you activate your ABS brakes stomp on your brake pedal and don t let up until you stop?
Keep your foot on the brake. Maintain firm and continuous pressure on the brake while steering to enable four-wheel ABS to work properly. Avoid pumping the brake, even if the brake pedal is pulsating. In light trucks that are equipped only with rear-wheel anti-lock brakes, however, the front wheels can still lock up.
How do you activate ABS to bleed brakes?
In general, whenever you are bleeding an ABS-equipped vehicle you can do so exactly as you would any other vehicle – stroke the pedal to pressurize the system, open a bleeder, close the same bleeder, and repeat. This does not change whether you are pressure-bleeding, vacuum-bleeding, or manual-bleeding.
How do you bleed ABS without scanner?
To properly bleed all the air from the system, there needs to be NO boost. Just pump the brake pedal until a solid pedal is felt, then bleed each caliper (if equipped) until the air is evacuated. Bleed brakes (at the calipers) with the engine off. The only pump that runs would be for the ABS system.
Do you need to bleed brakes when changing ABS module?
Yes, if you pass enough fluid during a normal flush, you will refresh the fluid in the ABS unit as long as it hasn’t been replaced. If you replace it and introduce air into the unit, THEN you need to bleed it. Same goes for master cylinder etc. Just bleed normally.
Does car need to be running to bleed ABS brakes?
You don’t want the mess or the potential fluid injection. If you have to you can turn the key on to activate ABS to help bleed but again engine always off.
Can air be trapped in ABS module?
Because the ABS unit has lots of small passages for all the valves, the air will get trapped (think about air rising up a tube that is closed at the top end). Since air is compressible, it will cause spongy brakes if it’s anywhere in the hydraulic system, even if it’s branched off in an ABS passage.
How do you bleed air from ABS module without scan tool?
The general procedure is find some sand, gravel, ice, or snow, and drive around locking all the wheels up to activate ABS to purge air out, then bleed the brakes, then repeat till normal ABS function is observed and no sponginess.
Is there a bleeder on the ABS module?
Most ABS modules do have bleeding valves but usually, these are not enough to take all the air out. While it is time-consuming work for a DIY-er, the process is not too complicated.
Do you bleed brakes with reservoir cap on or off?
Locate your brake master cylinder reservoir’s brake fluid level, usually located under-the-hood. Ensure that your car has the appropriate amount of fluid. While you’re bleeding the brakes, you’ll want to be sure that you leave the master cylinder cap unscrewed but rest it on top of the reservoir.
