Brake pipes — replacement

Before unscrewing the fittings of the brake pipes, it is necessary to clean the joints from dirt and apply a penetrating lubricant. To unscrew the fittings of the brake pipes, special wrenches are used, covering the five faces of the fitting and preventing them from collapsing.

The operation is shown on the example of a brake pipe connecting the pressure regulator to the rear brake hose.

To carry out the work, you will need an assistant, as well as a special wrench for 10 mm for brake pipes, a transparent vinyl pipe of a suitable diameter, a container for draining brake fluid, fresh brake fluid (see "Operating fluids").

Removing

1. We prepare the car for operations (see "Vehicle preparation for maintenance and repair").

2. Using an 8 mm socket wrench, unscrew the screws of the two brackets for attaching the brake tube to the bottom of the body.



3. Using a special 10 mm wrench, unscrew the connecting fittings securing the tube to the pressure regulator (see below "Brake pressure regulator - check and replace") and hose end (see above "Rear brake hose - replacement").

4. Remove the brake pipe.

Installation

1. Install a new brake pipe in reverse order.

2. Fill the reservoir with brake fluid and pump the hydraulic drive (see "Hydraulic brakes - pumping and replacing brake fluid").
