Replacement
Flexible brake hoses
1. Loosen the wheel nuts, jack up the vehicle and place it on jack stands. Remove wheels.
2. On the frame bracket, release the nipple connector for connecting the flexible hose to the rigid brake line.
Note. Loosening the nuts of the nipple connectors in order to avoid rounding of their slots should be done using a special ring wrench with a split head.
3. Using pliers, remove the U-lock and release the hose from the bracket on the vehicle frame.
4. To disconnect the hose from the brake caliper, unscrew the hollow bolt of the union connector. Please note that there is a copper sealing washer on both sides of the connector, which must be replaced during assembly without fail.
5. Remove the U-clamp and release the hose from the bracket on the suspension strut.
6. To install the hose, thread the corresponding fitting into the bracket on the suspension strut, then screw in the hollow bolt of the fitting connector on the caliper (don't forget to replace the sealing washers). After making sure that the locking tab of the union connector is in the mating hole on the caliper body, tighten the hollow bolt with the required force.
7. Push the metal holder into the bracket on the stand and snap the U-lock into place. Make sure the hose is not kinked between the caliper and strut bracket.
8. Insert the hose into the bracket on the vehicle frame (again try not to twist) and connect it to the metal line fitting. Install retainer and E-ring (with appropriate equipment), then firmly tighten the connector.
9. Bleed the brake caliper (see Section Bleeding the brake system).
10. Replace the wheels, lower the vehicle to the ground and tighten the wheel nuts to the required torque (see chapter Settings and ongoing maintenance).
Metal brake lines
1. When replacing rigid brake lines, special attention should be paid to the selection of replacement components. In no case should copper pipes be installed in the hydraulic path of the brake system that are not able to withstand the forces developed in the circuits. Try to purchase branded steel lines in the representative offices of the car manufacturer - it is preferable to buy sections already cut to length and equipped with fitting nozzles.
2. Rigid hydraulic lines are usually fixed along their entire length in special clamps. When removing the line, make sure that it is released from all clamps. Do not forget to replace the failed clamps.
3. When installing new steel lines, make sure that they are securely fixed in all provided brackets, clamps and clamps. Do not run pipes too close to moving suspension and steering components.
4. After installing the new sections of hydraulic lines, check the fluid level in the GTZ reservoir. Make appropriate adjustments if necessary. Bleed the brake system (see Section Bleeding the brake system). Before starting the operation of the vehicle, make sure that the brakes are working properly.
