What kind of brake fluid to fill in Toyota cars

Hello everyone again, today I’ll tell you how to change Toyota brake fluid, and which one is better to choose as a replacement. The brake fluid of any car has to be changed, and the Toyota Corolla is no exception. This happens due to its hygroscopicity, the ability to absorb water vapor and gradually become saturated with water. In this case, the properties are greatly reduced, and the brakes can fail, and this is life-threatening. Therefore, replacement in the Camry v40 and other TJ models is inevitable.

How do brakes work?

All modern cars are equipped with hydraulic braking, and Toyota Rav 4 too. I’ll tell you in a simplified way the mechanism of its operation:

• When the brake pedal is pressed, pressure is applied to the piston (through the rod) inside the main brake cylinder.
• The movement of the piston pumps fluid through the brake system, through pipes to the working cylinders.
• The working cylinders cause the pads to be pressed against the brake discs (or drums, if the brakes are drum).
• Friction occurs, reducing the speed of rotation of the wheels, and the car stops.

The operation of hydraulic systems is based on the property of a fluid to maintain volume and not compress under pressure.

Theoretically, any liquid is suitable for braking the Camry Grace - water, oil and others. In reality, the brake fluid must have a number of properties, otherwise the brakes will malfunction. And this, you see, is unacceptable.

Because of the friction that slows down the car, the braking elements (pads, drums, discs) become very hot, which causes heating of the fluid in the hydraulic system. The liquid boils, bubbles appear, which are easily compressed. When you press the pedal, the force is not transferred fully, it is lost to compress the bubbles, and braking occurs more slowly or does not occur at all.

Therefore, as a brake for the Camry V40, you need a fluid with a high boiling point. In addition, the pistons of the system need lubrication, which means it must have lubricating properties. Using simple oil for Prado 150 is impossible because it thickens in cold weather. The fluid in the brake system should not freeze or thicken during the cold season. Otherwise, you will find yourself without brakes in the winter, a season when working brakes are needed more than ever.

It turns out that modern fuel oils are a mixture of several substances of different properties with the addition of additives. This allows it to serve in any conditions (at different temperatures), while maintaining the desired properties.

Timely replacement of brake fluid in Avensis is the key to uninterrupted operation of the brakes.

Bleeding the car brake system

Now we need to bleed the brakes to remove the air remaining in the pipeline, and at the same time I completely replaced the brake fluid. We pull the tube onto the bleeder fitting, and lower the other end of the hose into a bottle to collect the old brake fluid. Later I removed the bottle and the hose, since constantly running around and changing the bottle is inconvenient. And in general it is better, of course, to perform this operation together.

Bleeding the brakes

Since I was alone, I took a wooden block, made a couple of presses on the brake pedal and pressed the block with the seat, the task is of course tedious, so it’s better to take an assistant with you, the process of pumping the brakes and clutch will go much faster.

Which one to choose

I will not tell the story of the creation of TJ, and list all the existing and once existing varieties. Because you won't need it. For Toyota Corolla, and other cars of the famous family, you need to choose from the options that exist today.

You should not bother with a specific manufacturer; this is not the main indicator when choosing. The main thing is that they comply with international standards. However, it is worth remembering about counterfeits, so purchase goods in specialized and branded outlets, with original branded labels, logos on packaging and protective holograms.

On the market today there are liquids of such standards as DOT-3, 4 and 5. Each of them has its own chemical composition and slightly different properties. Take a closer look at each:

• DOT-3. It has a boiling point of 205 degrees Celsius. Contains glycol as a base. Aggressive to rubber gaskets and products, capable of corroding paintwork. Therefore, do not allow drops of Dot 3 to get on the car body, and if it does, wash it off immediately. It is hygroscopic (absorbs moisture from the air);
• DOT-4. Its boiling point is 230 degrees. The base is again glycol, so the risk of damage to paint surfaces remains. Although, Dot 4 rubber does not corrode, unlike the previous standard, and is less hygroscopic;
• DOT-5.1. Boils at 275 degrees. Hygroscopicity is high. Does not harm rubber products, but is dangerous for paintwork;
• DOT-5. The most modern liquid, silicone based. Boils at 250 degrees, safe for rubber and paint. Practically does not absorb water;

In addition, there are categories within the standards that have improved characteristics, but are not provided for by the classification:

• DOT-4 can be found as DOT-4.5 or DOT-4 Super;
• There are also DOT-4/ABS and DOT-5/ABS, for cars with ABS systems;

In terms of color, the standards differ as follows:

• DOT-3 and 4 – yellow in color (ranges from light to almost brown);
• DOT-5 – has a pink or red color;

For Camry v50 and other branded Toyota cars, the Dot-4 standard, branded, is recommended.

For any other car, you need to use the fluid that is recommended by the manufacturer and written in the car manual. The volume of the rav4 (Toyota rav4) brake system is about a liter. For cars with a smaller volume, you still need to purchase a liter, which will be useful for refilling.

Replacing brake fluid

Bleed the brake system to remove air from it, see. Close the brake master cylinder reservoir with a plug. Remove the hoses from the air release valves and put protective caps on them. The fluid in the clutch hydraulic drive is replaced in the same way. It is advisable to do this before the MAX mark.

You don’t have to close the tank, but you just need to cover it so that various dirt doesn’t get in there. After the liquid has been filled in and you have covered the expansion tank, we begin to unscrew the fitting; as a rule, there are enough revolutions. You must first prepare the drain hose and jar.

Mixing liquids

Mixing glycol-based brake fluid is allowed, provided that the brake fluid added to the system is of the same class or higher class than that already filled in the system. That is, adding DOT-4 to the Auris 2007 if it is possible in the DOT-3 system, but on the contrary, it is not advisable. Remember that this will reduce its properties, which means there is a risk of brake failure. It is better to mix liquids from the same manufacturer; different manufacturers use different additives. Glycol and silicone compounds cannot be mixed. They are completely incompatible, so the braking system will work poorly or not work at all.

Note: DOT-5 fluid is recommended for use only in new cars with fully functioning brake systems. It has an extremely low viscosity; leakage occurs in old, worn cylinders, for example a 2005 Avensis.

Toyota Corolla and Auris with diesel engines

When selecting oil for a Toyota Corolla with a diesel engine, you need to pay attention to the presence or absence of a particulate filter (DPF) in the car. Particulate filters are very sensitive to the content of solid particles in the exhaust, and therefore require the use of motor oils of the Low SAPS category with a low sulfate ash content, and a reduced content of phosphorus and sulfur. In the TOTAL line, TOTAL QUARTZ INEO FIRST 0W-30 and TOTAL QUARTZ INEO ECS 5W-30 have the required composition. These oils meet the ACEA C2 standard and provide high wear protection and also help reduce fuel consumption.

For diesel cars without a particulate filter, TOTAL QUARTZ 9000 FUTURE NFC 5W-30 oil, produced using synthetic technology and meeting international standards API SL/CF and ACEA A5/B5, is suitable. During tests, this oil showed fuel consumption 3.3% lower than the reference value, and wear of engine parts 30% lower than ACEA requirements. The oil's high resistance to oxidation allows it to be used for a long time under any operating conditions.

How is TZ filled?

Replacing brake fluid is not a complicated procedure, but you will need an assistant. Among the tools, a key “8” is useful, and there are also specialized ones for bleeding brakes. A flexible tube that can easily be pulled over the drain fitting, and a container for draining the liquid. Replacing a TJ in a Toyota Corolla E150 is done as follows:

• It is more convenient to work from an overpass. An inspection hole is also suitable, and for those who like to lie on the floor, a jack and a wooden block will be enough for insurance;
• Install shoes and other stops to prevent the car from accidentally rolling;
• Finding the master cylinder is easy; in the Toyota Corolla 150 it is located on the right side of the hood, closer to the windshield;
• The easiest way to pump out old fluid is with a large syringe with a needle or a dropper tube instead of a needle;
• Having emptied the Corolla 120 tank, you need to go downstairs and unscrew the fittings on the brake cylinders one by one, and drain the used fuel oil through the tube into a substitute container.

Important: If the waste liquid is thick and has sediment, it is better to flush the system with a special compound or alcohol.

• To flush, pour a special substance (or alcohol) into the master cylinder reservoir. The assistant presses the brake pedal in the cabin, and from below you drain the fluid from each cylinder in turn until a clean flush occurs;
• Having finished lowering and flushing the system, if necessary, fill the master cylinder tank with a new TJ, by pouring liquid into the tank with one pour, the replacement in the Corolla TJ does not end.
• Pump the liquid in the same way as when flushing, starting from the farthest wheel (to which the longest tubes go);
• The procedure for bleeding the Land Cruiser 200 is like any car, first the rear circuit, then the front. With mixed contours, the rear wheel, then the corresponding front wheel, the second rear and the second front;
• In the cabin, the assistant presses the pedal 3-5 times and keeps it pressed;
• At the bottom, unscrew the fitting and release the fuel fluid; if there are bubbles in it, tighten the fitting, after which the cycle is repeated, pressing the pedal in the cabin;
• This is how the cylinders of all wheels are pumped; do not forget to check the presence of fuel fluid in the master cylinder reservoir after pumping each working cylinder. If all the liquid leaves, air will enter the system, and then replacing the Corolla 120 TJ begins anew;

This completes the replacement of the TJ Hilux. All that remains is to fill the main cylinder reservoir to the level and close its lid.

Tuning price

The cost of tuning a Toyota Corolla hatchback or sedan in the 120 body and the E150 model depends on the type of work performed:

1. External tuning, which includes repainting, installing body kits, applying airbrushing, installing underbody lighting, replacing rims and installing additional air ducts, deflectors and spoilers, will cost the driver 25-45 thousand rubles.
2. Chip tuning of the engine, replacement of parts with more advanced ones, modernization of the suspension (installation of stiffer or softer springs), replacement of brakes - 30-50 thousand rubles. Installation of hydraulics or electrohydraulics will cost drivers 10-15 thousand rubles.
3. Arranging the interior, reupholstering the upholstery of the seats, dashboard and body, replacing the audio system and acoustics, and improving sound insulation will cost 25-30 thousand rubles. When using seat covers, the cost of work can be reduced by 5-10 thousand rubles.

To improve driving performance, design and increase comfort of use, Corolla 110, Toyota Corolla 100, Toyota Corolla 130 and 150 cars are tuned. These cars are distinguished by their unpretentiousness, reliability and high maintainability. You can buy Japanese cars of these models at a low price. And by investing a little in car tuning, you can get a beautiful, comfortable and powerful vehicle.

How often is this done

Replacing the fuel fluid in a car is required periodically, even if everything works well. This is due to the hygroscopicity of liquids of this type. In a Corolla '14, it is necessary to change the TZ, even if you have not driven it. Gradually taking water from the air, it loses its properties and the boiling point decreases. Having lost half its properties, it is no longer suitable for use, because the brakes will not work at full strength.

Changing the fluid in Toyota Venza and other cars of this family is recommended every 40-50 thousand kilometers traveled. Or every 2-3 years, if during this time you have not driven that many kilometers.

That’s all, friends, now you know what kind of brake fluid to fill in a Toyota Corolla, and how to replace it, if necessary. All that remains is to subscribe to my blog and send the link to your friends so that they can subscribe too. Until next time.

Oil for Toyota Corolla E120

The Corolla E120 was produced from 2001 to 2007. The manufacturer recommends using synthetic oils with a viscosity of 5W-30 in the internal combustion engine of the Toyota Corolla E120. Semi-synthetic 10W-30 is also suitable, but in the climatic conditions of Russia, owners more often choose 5W30 synthetics.

Preference is mainly given to the following oils:

• Toyota SN - original,
• Shell 5W-30,
• Castrol GTX 5w-30,
• Mobil Super 3000 5w-

The lubricant filling volume depends on the engine type and its size. Thus, the Toyota Corolla 1.6 engine (3ZZ-FE) will require 3.7 liters of oil, as well as the most popular 1.5 engine (1NZ-FE) in this body. But diesel Corollas need almost 6 liters.
