Attention: It is better to replace rigid brake pipes made of metal in a workshop, because. experience is required for a quality installation.
Tight, pressure-resistant brake hoses are used as flexible connections between fixed and moving vehicle parts, such as brake calipers. If visible damage is found, the hoses must be replaced.
Attention: Brake hoses must not be exposed to oil or gasoline, hoses must not be painted or coated with protective compounds.
Removing
Attention: Observe the rules for handling brake fluid.
Raise and support the vehicle.
Remove brake caliper.
Loosen the cap nut (1), while holding the brake hose by the hexagon (2). Pull out the clamp (3) and remove the brake hose (4) from the holder (5).
Attention: Collect leaking brake fluid with a cloth. If necessary, seal the open connection of the brake pipe.
Installation
Use only original brake hoses. Install new brake hose (arrow) in the same position as before removal and tighten its fasteners to 15 Nm.
Install the brake caliper.
Remove air from the brake system.
After installing the hose with the front wheels suspended, turn the wheels left and right as far as they will go and make sure that the hose follows all the movements of the wheels and does not rub anywhere on other parts and wheels.
Lower the car.
With the vehicle on the ground, check that the brake hose follows the wheels and that it does not rub against other parts.
Conduct a security check.
Security check
Are the brake lines tight?
Is the brake hose in the mount?
Are the bleed valves tight?
Is there enough brake fluid?
Carry out a density test with the engine running. To do this, press the brake pedal with a force of 200-300 N (20-30 kg) for about 10 seconds. The brake pedal must not go down. Check all connections for tightness.
In conclusion, brake the car several times on a road with little traffic.
