- Using a siphon-pear pump out the brake fluid reservoir 3 (Fig. 327), after it is laid out a sieve;
A warning Do not pump the brake fluid through the hose mouth - brake fluid is poisonous. |
- Disconnect the wires from the terminals to the sensor Emergency brake fluid level; - Disconnect the hose clutch master cylinder; - If necessary, remove the brake master cylinder reservoir, shaking it back and forth. Be careful - the residual brake fluid could leak out. Put the cloth; - Mark and disconnect pipes from the master cylinder and gently bend them aside; - Close the hole at the pipeline and the master cylinder to prevent fluid leakage and the ingress of dust and dirt; - Remove the cylinder by unscrewing the nut of its fastening to the vacuum amplifier; - Remove the rubber sealing ring 7 (see. Fig. 327). Installation - master cylinder spend in reverse order, with the following: - Rubber sealing ring 7, always replace a new; - 5 nuts securing the master cylinder to the vacuum amplifier 9 tighten the moment 25 Nm; - Coupling nuts brake lines tighten the moment 13 Nm; - Push rod servo is not regulated; - Lubricate the brake fluid connecting sleeve 4 and push them into the tank; - After the installation of the main brake cylinder to restore the level of liquid in a tank and pump over hydraulic drive system.
