Folksvagen Sharan/Sharan repair>> Brake system>> The main brake cylinder>> Removal and installation of the main brake cylinder
The main brake cylinder is located in a motor compartment of the engine and fastens nuts to the vacuum amplifier.
Removal of the main brake cylinder spend in a following order:
- Before the work beginning press 5 — 6 times a brake pedal at the idle engine to create in vacuum and atmospheric chambers of the vacuum amplifier the identical pressure close to atmospheric (remove vacuum разряжение);
- Disconnect a vacuum hose from the vacuum amplifier;

Fig. 327. Fastening of the main brake cylinder: 1 — a cover of a tank with plugs of the gauge of emergency level of a brake liquid; 2 — a float; 3 — a tank; 4 — connecting plugs; 5 — a nut, 25 Нм; 6 — the main brake cylinder; 7 — a sealing ring; 8 — a flange of fastening of a tip of a hose; 9 — the vacuum amplifier





- By means of a siphon-pear pump out a brake liquid from a tank 3 (fig. 327) after the sieve will be taken out;

The prevention
Never pump out a brake liquid a mouth through a hose — the brake liquid is poisonous.

- Disconnect колодку with wires from plugs of the gauge of emergency level of a brake liquid;
- Disconnect a hose of the main cylinder of coupling;
- If necessary remove from the main brake cylinder a tank, having shaken it forward-back. Be attentive — the residual brake liquid can flow out outside. Put a rag;
- Mark and disconnect pipelines from the main cylinder and cautiously unbend them aside;
- Close apertures at pipelines and at the main cylinder to warn leak of a liquid and hit in them a dust, a dirt;
- Remove the cylinder, having turned away a nut of its fastening to the vacuum amplifier;
- Remove a rubber sealing ring 7 (fig. 327 see).
Installation - the main brake cylinder spend in an order, the return to removal, taking into account the following:
- Rubber sealing ring 7, always replace with the new;
- Nuts of 5 fastenings of the main brake cylinder to the vacuum amplifier 9 tighten the moment 25 Нм;
- накидные nuts of pipelines of a brake drive tighten the moment 13 Нм;
- The bar of a pusher of the vacuum amplifier is not regulated;
- Grease with a brake liquid connecting plugs 4 and press into them a tank;
- After installation of the main brake cylinder restore liquid level in a tank and pump over hydrodrive system.
