Attention! Jacking up the vehicle or placing it on jackstands carries the risk of injury. Therefore, it is recommended that you familiarize yourself with the safety precautions outlined in chapter «car jacking».
1. Jack up the car and jack it up.
2. Clean the brake lines.
Attention! The pipelines of the brake system are made of metal and coated with a layer of polymer material to prevent corrosion. If the protective polymer layer is damaged, the pipeline may rust. Therefore, cleaning the brake lines with a wire brush or sandpaper is not permitted.
3. Check up, lighting by a lantern, tightness of the pipelines of the brake mechanism going from the main brake cylinder to ABS, and also to all four wheel brake mechanisms.
The master brake cylinder is located in the engine compartment under the brake fluid expansion tank.
No kinks or dents are allowed on the pipelines of the brake system. They should not have corrosion pits or worn areas.
Otherwise, the pipeline to the next joint should be replaced with a new one.
Brake hoses connect pipelines to the wheel brake cylinders and are routed near the moving parts of the vehicle.
They are made of high pressure material, but over time they can become porous, swell, or be cut by sharp objects.
In the presence of at least one of these defects, the brake hose must be replaced.
4. Locate damage by bending the brake hoses (see illustration). The hoses must not be twisted.
Refer to color markings on hoses, if available.
Joints of pipelines and hoses must not be wet.
The presence of moisture is evidence of a brake fluid leak.
5. Turn the steering wheel all the way to the left and then to the right. Brake hoses must not touch other parts of the vehicle in any position of the wheels.
6. Lower the car on wheels.
7. Turn the steering wheel again all the way to the left and then to the right. Brake hoses must not touch other parts of the vehicle in any position of the wheels.
