Checking the tightness of the hydraulic brake system Audi A4

Tools:

• screw jack

Notes:

The brake system mainly uses steel brake pipes, with the exception of flexible reinforced hoses at the front wheels and as connections at the rear axle. Regular inspection of all these lines is very important.

1 . Jack up the vehicle and place it securely on jack stands.

Screw jack.

2 . Remove the wheels (refer to Checking the condition of the tires and the pressure in them. Marking the tires and wheel rims. Rotating and changing wheels ).

3 . Check all brake lines and hoses for cracks or chafing in their outer coating, leaks, swelling or deformation. Check the brake hoses at the front and rear of the vehicle for signs of softening, cracking, deformation, or wear due to rubbing against other components. Check all fittings for signs of leaks and make sure all bolts and brake hose clamps are secure.

4 . Bend the brake hose back and forth with your hands to check for damage. Hoses should not be twisted. Pay attention to the direction of the colored line marked on the hose!

5 . Turn the steering wheel right and left as far as it will go. The hoses must not touch the structural elements of the vehicle. If fluid leaks or damage is found, they must be repaired immediately.
