Mercedes C-Class

1. Mark with paint the provision of forward wheels concerning naves. It will allow to establish at assembly an otbalansirovanny wheel in its former situation. Weaken bolts of fastening of a wheel before a car poddomkrachivaniye. Lift a forward part of the car, put it on supports and remove forward wheels.

Operation of lifting and car installation on supports is connected with danger! Therefore before carrying out operation familiarize with Poddomkrachivaniye's Section and Introduction towage to the management.

2. Right brake: Take out the tip (1) sensor of wear from the socket. Thus do not pull for a cable (2). Disconnect a wire (3) sensor of wear from holders.

3. Turn out bolts of fastening (4) above and below.

4. Take out a support (1) of directing blocks.

5. Fix a support a tape (2) or a wire on an amortization rack. Thus do not disconnect a brake hose. Otherwise after installation it is necessary to delete air from brake system. Watch that the hose was not tense.

Do not press a brake pedal at the removed support. Otherwise the piston of the brake cylinder will be squeezed out from the case. If the piston was casually squeezed out, remove a support and hand over on HUNDRED for assembly.

6. To protection the piston of the brake cylinder from expression by whetstone of a tree (1).

7. Take out brake shoes (2) of the directing.
8. If the removed brake shoes are applied, mark them ("internal", "external"). Thus, them it is possible awaking to establish on a former place.

1. Clear surfaces of sliding and a place of landing of brake shoes on directing a wire brush from light metal, and also wipe a brake disk a rag moistened in alcohol. Do not apply to this purpose mineral solvents or the tool with sharp edges.

To cleaning of a brake apply only alcohol.

2. Before installation of brake shoes check hand fingers a brake disk on existence of flutes. In the presence of flutes a disk it is possible to pierce (work HUNDRED) if the disk has even sufficient thickness. Otherwise replace a disk.
3. Measure thickness of a brake disk as it is described in the Section Check of a brake disk.
4. Check lock brackets, if necessary replace with the new.
5. Check an antisplash cover of the piston on existence of damages. The damaged cover urgently replace, since penetration of dirt can lead to violation of tightness of a support. For this purpose it is necessary to disassemble a support (work HUNDRED).
6. Check, whether brake liquid follows from under the piston. If necessary repair a support on HUNDRED or replace it new.
7. Check also protective cover of directing fingers of a support and in the presence of damages replace.

At big wear of brake shoes check ease of a piston stroke. For this purpose insert into a support wooden whetstone and ask the assistant to press a brake pedal slowly. The piston should be pressed and squeezed out easily. For check other brake shoe and an opposite support should be inserted. At a heavy piston stroke replace a support.

8. Right brake: Take out from the socket on a brake shoe the sensor of wear (1). The damaged sensor of wear replace new. (2) – tip of the sensor of wear.

2. Insert brake shoes sideways at an angle into lock brackets on directing blocks. If are established already applied before a block watch that they were established on the former places.

On frictional surfaces of a brake disk and brake shoes there should not be no greasing or oil.

3. Insert a support on the place in directing blocks.
4. Screw new being self-stopped bolts at the top of and in the bottom of a support and tighten them the moment 25Нм.
5. Right brake: Enter the tip of the sensor of wear into the socket. Insert a wire of the sensor of wear in holders.
6. Establish into place forward wheels so that the marks put at removal coincided. Previously grease with a thin layer of bearing greasing aligning belt of a disk of a wheel on a nave. Bolts of fastening of wheels do not grease. Rusty bolts replace. Wrap bolts. Lower the car on wheels and tighten bolts cross-wise the moment 110Нм.

Several times, strongly press a brake pedal until notable resistance will be felt. Thus, brake shoes adjoin to a disk and occupy the working situation.

7. Check level of brake liquid in the tank, if necessary add liquid to MAX mark.
8. New brake shoes carefully earn extra. For this purpose several times brake the car from speed of 80 km/h to the speed 9. km/h, slightly pressing a brake pedal. Between braking let's to a brake be cooled. The first 200 km of movement do not apply needlessly strong braking of the car.

In some regions brake shoes should be utilized in a special way. Local authorities provide information on possibility of utilization of a special waste.

Carry out reliability control:

· Whether brake hoses are fixed?
· Whether the brake hose in the holder is fixed?
· Whether unions for air removal are tightened?
· Whether enough of brake liquid is filled in?
· On the working engine check tightness. For this purpose press a brake pedal effort of 200-300 N (20-30 kg) during 10 pages. The pedal should not weaken. Check all accessions on tightness.

Operation of lifting and car installation on supports is connected with danger! Therefore before carrying out operation familiarize with Poddomkrachivaniye's Section and Introduction towage to the management.

2. Disunite the socket (1) sensor of wear (2). Thus do not pull for a cable. At assembly the wire should be laid how it is shown on an illustration.

3. Beat out the corresponding drift (3 mm) two pins outside inside from a support. Remove a shaped spring (1).

4. Take out flat-nose pliers or a screw-driver brake shoes. If they приржавели, the special adaptation (for example is required, to HAZET No. 1966-2).
5. If former brake shoes are applied, mark them ("internal", "external"). Thus it will be possible to establish them on former places.

Do not press a brake pedal at the removed support. Otherwise the piston of the brake cylinder will be squeezed out from the case. If the piston was casually squeezed out, remove a support and hand over on HUNDRED for assembly.

1. By means of the adaptation squeeze out both pistons. It can be made also by means of the hammer handle.

2. For an exception of a gnash of disk brakes reverse sides of brake shoes, and also lateral faces of a return plate (arrows on an illustration) can be greased with a thin layer of brake paste (for example, high-temperature copper paste, Plastilube, Liqui Moly LM-36 or LM-508-ASC). By no means paste should not get on brake shoes or a brake disk. If necessary paste it is necessary to remove and wash out immediately places alcohol.

3. Remove the wear sensor from old brake shoes and insert into new blocks. In the presence of damage of the sensor it is necessary to replace it.
4. Insert brake shoes into a support. If the blocks which were in work are established, check, that they rose on the former places.
5. Insert a cable of the sensor of wear into the socket on a support. Lay a cable according to its route.
6. Establish a new shaped spring and put new pins by means of a drift. A drift hammer against the stop.

Shaped spring and pins surely replace with the new.

7. Establish into place forward wheels so that the marks put at removal coincided. Previously grease with a thin layer of bearing greasing aligning belt of a disk of a wheel on a nave. Bolts of fastening of wheels do not grease. Rusty bolts replace. Wrap bolts. Lower the car on wheels and tighten bolts cross-wise the moment 110Нм.
