Before unscrewing the brake pipe fittings, it is necessary to clean the connection points from dirt and apply penetrating lubricant. To unscrew the brake pipe fittings, special keys are used that cover five edges of the fitting and prevent them from being crushed.
The operation is shown using the example of a brake pipe connecting the pressure regulator to the rear brake hose.
To complete the work you will need an assistant and a special key by 10 mm for brake pipes, transparent vinyl tube of suitable diameter, container for draining brake fluid, fresh brake fluid (see "Operating fluids").
Removal
1. Prepare the vehicle for operations (see "Preparing a car for maintenance and repair").
2. With a socket wrench by 8 mm we unscrew the screws of the two brackets that secure the brake pipe to the bottom of the body.
3. With a special key by 10 mm we unscrew the connecting fittings for attaching the tube to the pressure regulator (see below "Brake Pressure Regulator - Checking and Replacing") and the hose tip (see above "Rear Brake Hose - Replacement").
4. Remove the brake pipe.
Installation
1. Install the new brake pipe in reverse order.
2. Fill the reservoir with brake fluid and bleed the hydraulic drive (see "Hydraulic brake drive - bleeding and replacing brake fluid").
