Sequence of works
1. First loosen the union nut of the corresponding brake pipe. Make sure that the pipe does not turn, holding it on the hose flanges.
2. If the brake hose is additionally secured to the body with a metal bracket that prevents the hose from chafing, then do not forget to put it back in place during assembly.
3. To disconnect the brake hose from the caliper, first clamp it with a small clamp or a special clip. Do not clamp the hose too tightly, so as not to damage it.
4. Loosen the nipple that secures the hose to the brake caliper. Remove the brake caliper and disconnect the hose from it. To prevent brake fluid from leaking out of the brake system, plug the hose with a plug.
5. First, connect the hose to the brake caliper with a torque of 18 Nm.

6. Then attach the new hose (branded or equivalent) to the brake pipe and tighten the threaded fastening to the brake pipe to a torque of 15 N·m.
7. When installing, make sure that the brake hose is not twisted. Correct installation can be checked by the colored strip or rubber comb along the hose along its entire length.
8. On the front brake mechanism, secure the hose to the steering knuckle with a special clamp. It also holds the brake pad wear sensor wire.
9. Bleed the brake system.
10. After finishing, be sure to check whether the brake hose rubs against anything when the suspension is compressed or the steering is operated. Repeat the check after some mileage.
