2. Each time during maintenance, check all elements of the brake system for cracks, signs of damage to the containment, signs of fluid leaks, swelling and other damage. The hoses are the critical and most vulnerable part of the brake system, so they must be inspected with the utmost care. If any, even minor, damage or signs of damage is detected, the suspected hose must be replaced.
Attention: Do not allow brake hoses to come into contact with oil and gasoline, do not expose them to painting, as well as to special compounds for anti-corrosion protection of the bottom.
3. Over time, during the operation of the car, old brake hoses can swell, while their flow area decreases - this makes it difficult for the brake fluid to return to the GTZ and the brake pads to be completely removed from the disc. As a result, the brake mechanisms heat up, which can lead to failure of both the mechanisms themselves and the wheel bearings.
4. Replacement steel and flexible brake lines can always be purchased at branded service stations, as well as in branded auto accessories stores.
Attention: In no case should you use any tubes as replacements, except for branded ones, specially designed for installation in the brake circuit of your car.
5. If it is necessary to replace the metal brake lines, you must contact the Opel service station, because. their laying requires a certain skill and qualification - careless handling can lead to bending of the tubes and affect the size of the flow area of the channel. Brake lines must be at least 20 mm away from moving or vibrating body, suspension or steering components. During installation, all standard clamps and line holders must be used.
6. Before replacing the hose, check the brake fluid level in the reservoir and top up if necessary. Remove the corresponding wheel. Have plugs ready to plug the brake lines after disconnecting them, and a rag to clean up spilled brake fluid. Drain the reservoir if necessary.
Replacing the brake hose of the front wheel
7. To loosen the flexible hose fittings with the steel tubing of the hydraulic lines, use a special box wrench with a split head. After releasing the union nut, remove the retaining clip and release the brake hose from the support bracket (see resist. illustration) in the wheel arch, - the retaining clip must be reinstalled after the hose has been disconnected. Immediately close the brake pipe with the prepared plug.

8. Remove the hollow bolt (see resist. illustration) and disconnect the brake hose from the caliper fitting and remove the hose. Remove the old sealing washers - during assembly, the washers must be replaced without fail.

9. Make sure that the new brake hoses exactly match the dimensions and specifications removed from the car.
10. Fix a brake hose with new sealing rings on a support, tighten a hollow bolt with the demanded effort. Then remove the plug and connect the hose to the metal brake line, tighten the union nut. After that, fix the hose in the intermediate holder on the shock absorber - make sure that the hose is not twisted during installation.
11. With the front wheels suspended, turn the steering wheel to the right and to the left - the hose should not interfere with the moving parts of the steering mechanism and come into contact with other structural elements.
12. After replacing the hose, be sure to bleed the air from the brake system using a special device (see Section 3). Check the fluid level in the GTZ reservoir, correct if necessary.
13. Before starting the operation of the car, make sure that the brakes are working properly.
Replacing the rear wheel brake hose
15. On Corsa-Eco models, remove the crankcase protection (see chapter 2).
16. Disconnect the ABS sensor wiring harness from the brake hose.
17. Disconnect the brake hose from the supply metal brake line (see paragraph 7). Similarly, on models equipped with drum-type rear brakes, the other end of the brake hose is also disconnected.
18. On models equipped with rear wheel disc brakes, the hose end (union) screwed directly into the caliper (see resist. illustration). Unscrew the fitting and remove the hose - be careful not to twist or damage the hose.

19. Installation is made in an order, the return to an order of removal. Bleed the brake system (see Section 3), correct the brake fluid level in the reservoir. Before starting the operation of the vehicle, make sure that the brakes are working properly.
