Folksvagen Sharan/Sharan repair>> Brake system>> Disk brakes of forward wheels>> Removal and installation of lobbies brake колодок
Operation on replacement brake колодок spend independently only in the event that there is an experience of this sort of carrying out of works as traffic safety and a personal security depend on it.
On the car it is necessary to establish only the brake mechanism from ATE (Teves) and brake колодки recommended by firm-manufacturer of the car of marks.

The prevention
Brake колодки change only in the complete set. At all do not rearrange колодки from an outer side of a brake disk on internal and on the contrary to balance possible deterioration. Establish only the details recommended «Volkswagen».

If it is planned to establish old brake колодки, before their removal mark with a paint (a marker, by a core) a relative positioning brake колодок in relation to supports that at installation not to mix internal both external brake колодки and a wheel, on which they have been established. Removal of lobbies brake колодок spend in a following order:
- Slightly release bolts of fastening of forward wheels;
- Mark with a paint (marker) a relative positioning of wheels, brake disks and naves of wheels;
- Lift a forward part of the car, put it on a support, turn away bolts of fastening and remove forward wheels;

Fig. 312. Removal of a spring collar with скобы the disk wheel brake mechanism





- Insert a screw-driver into a spring collar (fig. 312) and remove it from the fastening in the case of a brake support;

Fig. 313. The Locations of protective caps of directing fingers (are shown by arrows)





- By means of a narrow screw-driver take protective caps (fig. 313) directing fingers;

Fig. 314. Отворачивание the bottom and top directing fingers (bolts of fastening of a support do not turn out)





- Turn away the bottom and top directing fingers from a support face шестигранным a key (fig. 314) and take out them;

Fig. 315. The brake mechanism of a forward wheel: 1 — a disk of the brake mechanism, thickness of 25 mm; 2 — a bolt with internal шестигранником, 10 Н·м; 3 — a power shaft bolt, 200 Н·м; 4 — a wheel bolt, 140 Н·м; 5 — a protective casing; 6 — a bolt, 10 Н·м; 7 — the gauge of system ABS defining frequency of rotation of a wheel; 8 — a bolt, 10 Н·м; 9 — a gear rim of the gauge of frequency of rotation; 10 — a brake hose; 11 — a protective cap; 12 — a directing finger, 25 Н·м; 13 — the sliding plug; 14 — bolts, 200 Н·м; 15 — the brake cylinder in gathering with a support; 16 — a spring collar; 17 — скоба (directing колодок); 18 — brake колодки





- Raise a brake support, having moved it upwards and back, and tie up it to a body wire скобой. A brake hose 10 (fig. 315) do not disconnect, it should not be overwound, bent and be tense;
- Disconnect internal brake колодку from the brake piston and take it together with clamping скобой;
- Take from a brake support external brake колодку. If it has become attached, cautiously separate it by means of a screw-driver.

The prevention
It is forbidden at removed brake колодках to press a brake pedal as it will lead to loss of the piston from the brake cylinder, вытеканию to a brake liquid and system depressurization.

Check of a technical condition of the brake mechanism spend before installation of lobbies колодок in a following order:
- Clear all details and attentively check up their condition;
- Check up a condition of a surface of the piston and the cylinder. At their deterioration, damage or strong корродировании replace the cylinder and the piston. From the case of the cylinder corrosion remove a wire brush;
- Carefully clear directing surfaces and installation sites колодок in an aperture of the case a soft metal brush and wipe rags moistened in spirit (gasoline it is impossible to use). Do not use thus маслосодержащие solutions or sharp tools;

The prevention
All works on cleaning of brake mechanisms spend in protection frames of respiratory organs — respirators as the dust from brake колодок, allocated as a result of functioning of brake mechanisms is unhealthy.

- Check up, whether in apertures скобы the disk brake mechanism protective caps of directing fingers well sit. The hardened, torn protective caps replace;
- Check up fingers cleanliness of working surfaces of brake disks. Remove from them oil and a dirt. On its surface teases, коробление are not supposed, deep risks, and also other damages from which deterioration of overlays increases or efficiency of braking decreases. Polishing or проточка a disk simultaneously from two parties is supposed, but thus both parties should be processed on identical depth, and the thickness of a disk should not be less admissible;

The prevention
Brake disks with корродированной a brake surface are subject to replacement.

- Measure a real thickness of brake disks and overlays brake колодок. Brake disks with dark blue or grey touch before installation new колодок should be cleared;
- Check up, whether there are no cracks on a dustproof cap of the piston of the brake cylinder. The damaged dustproof cap urgently replace, as the getting dust quickly leads to occurrence of leak of a brake liquid.
Installation of lobbies brake колодок spend in a following order:
- Remove a protective sticky film from a basic surface external brake колодки and accurately establish колодку in a support;

Fig. 316. Piston installation in the brake cylinder by means of a clamp





- By means of a vice (fig. 316) or wooden (plastic) оправки without warps move the piston in the brake cylinder. Watch to damaging a surface of the piston and a dustproof cap. At piston cave-in there is an increase of level of a brake liquid in a compensatory tank, therefore before утапливанием the piston pump out from a tank a siphon-pear a liquid part not to admit it выплескивания from a tank;
- Together with the assistant check up ease of a piston stroke. For this purpose in a support establish wooden брусок, slowly press and release a brake pedal. The piston of the brake cylinder should leave and enter easily back (thus other brake mechanisms should be in working order);
- Establish clips internal brake колодку in the cylinder piston;
- Establish external brake колодку in a support, an overlay to a brake disk. Колодки should be pure and precisely enter into the directing;

The note
At installation brake колодок do not damage glued substance on a metal plate.

- Cautiously establish a brake support on a brake disk, in its working position, enter pure directing fingers, turn and alternately tighten their moment 25 Н·м;
- Put on heads of directing fingers protective caps;
- Establish on a support a spring brake колодок. At wrong installation automatic подводка external brake колодки does not operate;
- Some times strongly press a brake pedal, yet will not feel strong counteraction. Thus brake колодки will occupy the working position and will provide good прилегание to a brake disk;
- Pump over brake system if it is necessary;
- Establish and temporarily fix (by hand) bolts of fastening of wheels;
- Lower the car and tighten bolts of fastening of wheels cross-wise;
- Check up connections on tightness. Podtekanie liquids it is not supposed;
- Check up level of a brake liquid in a compensatory tank and restore it to demanded level;
- Check up tightness of brake system on the working engine. For what press some times a pedal of a brake and keep it within several seconds. The pedal thus should not просаживаться.

The prevention
In process extra earnings new brake колодок sharp and long braking to a full stop is not recommended.
