2. Inspect all fittings for leaks and go to the brake hoses. Recent models have reinforced hoses, so check that the wire braid does not have defects that could damage the hose itself. Inspect hoses for chafing, cracks, cuts, and signs of leaks.
3. Inspect the brake pipes. They should be cleaned with a tube and inspected for dents, abrasion and corrosion. Slight corrosion is normal, but in advanced cases it can lead to leaks. Heavily corroded pipes must be replaced. Tube damage is especially likely under the underbody and along the rear suspension arms where the tubes are most exposed to the weather.
4. If necessary, disconnect the fitting (e.g. to replace a hose), seal the opening of the brake reservoir as indicated in section 6, paragraph 1). This will minimize brake fluid loss.
5. On older machines, you may find it difficult to replace the brake lines. An open end wrench or adjustable wrench is best for loosening fittings. In order to prevent the tubes from turning when connecting or disconnecting, use two keys: one for operation and the second for holding the tube.
6. Brake hoses are usually connected to the brake pipes on rigid support brackets. When disconnecting the hose from the tube, two keys are also required. If you run into a problem because the joint has rusted, it should be covered with penetrating oils and left there for a while.
7. After removing the brake hose, it can be checked from the inside. Blow out the hose with compressed air and look through it at the light. Any foreign matter in the hose indicates damage to the inner coating and the hose needs to be replaced.
8. Replacement brake pipes can be bought ready-made or ordered from a workshop. In this case, you will need an old tube as a sample.
9. Tubes are installed in the reverse order. Try not to bend the tubes yourself - this work should be done by a specialist with special equipment. Before installing new pipes, they should be blown out with compressed air.
10. After installing the tubes and tightening the fittings, remove the plastic film or plug with a sealed vent hole from the tank opening and bleed the brake system (see section 3).
