2.7.1. Check of brakes

GENERAL INFORMATION

Besides periodic check of a brake it is necessary to examine at each removal of a wheel or at suspicion for their abnormal work. Any of listed below indications can testify to possible malfunction of brakes:

  – by pressing a brake pedal the car withdraws aside;
  – squeal or a scratch when braking;
  – the brake way exceeds norm;
  – feeling of pushes of a pedal;
  – a podtekaniye of brake liquid (emergence of smudges on an internal surface of the tire).

PERFORMANCE ORDER
1. Brake shoes of disk brakes are supplied with the built-in display plates. At reduction of thickness of slips to a limiting plate publish squeal or a scratch. If when braking such sound is distributed, it is necessary to replace immediately blocks, the expensive brake disk otherwise will fail.
2. Release nuts of forward wheels.
3. Lift a forward part of the car and establish on supports.
4. Remove forward wheels.

Disk brakes

PERFORMANCE ORDER
1. On each wheel support of a brake there are two slips – internal and external. Overlays of forward brakes are visible through an observation port in a support. Having put to a window a steel ruler, it is possible to measure residual thickness.
2. Check thickness of each of slips, having examined them from above and from below a support and through an observation port in a support. If the thickness of slips is less than norm, slips replace.

Prevention

Keep in mind that the thickness of slips does not include thickness of a steel substrate of a block, to which slips fasten rivets or glue.


3. If to define residual thickness of a material of slips through an observation port it is not possible, or if you the general condition of blocks interests, remove a support and blocks for further survey (see subsection 9.3 and subsection 9.4).
4. After removal of blocks wash out them a cleaner of brake system and measure thickness of slips by a short steel ruler or a calliper.
5. Measure thickness of a brake disk, be convinced that the disk is still suitable for further operation. If thickness of any disk less maximum permissible (see subsection 9.1), a disk replace (see subsection 9.7). Check a disk condition irrespective of its residual thickness. At detection задиров, deep development and traces of a strong warming up remove a disk and прошлифуйте (see subsection 9.7).
6. Before installation of a wheel check a condition of all hoses and pipelines of a brake contour, existence on them of cracks, corrosion, podtekaniye of liquid, twistings or excesses, especially in places of fastening of rubber hoses on brake cylinders of a support. Be convinced that hoses and tubes are on sufficient removal from sharp edges, moving details and exhaust pipes. If hoses and tubes settle down too close from the specified details, unbend brake tubes or replace them, and also check and if necessary replace details of connections (see subsection 9.11).

Back drum-type brakes

PERFORMANCE ORDER
1. For check of thickness of brake overlays of back brakes there is no need to remove brake drums. Get rubber caps from a brake board, and having lit a small lamp, check thickness of slips. For more careful check of a condition of overlays of back brakes arrive as follows.
2. Remove brake drums (cм. subsection 9.8).
3. Check thickness of brake overlays of back blocks, check existence of traces of pollution by brake liquid or greasing. If the slip is pasted, the thickness from a block surface to a slip, as is shown in drawing if the slip приклепана to a block, is the defining size distance from slips to heads of rivets is measured.
4. If the thickness of kleeny slips less than 1,5 mm (or distance from slips to heads of rivets) is less than 1,5 mm, slips replace. It is necessary to replace slips also at detection of cracks, a glossy surface, or at pollution by brake liquid or greasing. Procedure of replacement is described in subsection 9.8
5. Check a condition of the top and bottom springs of blocks and correctness of their installation. At detection of extension or deformation of a spring replace, otherwise blocks will be taken away insufficiently from drums and quickly to wear out.
6. Check existence of traces of podtekaniye of brake liquid on wheel cylinders for what carefully hook and take away an external sealant of the cylinder. If under a sealant traces of brake liquid are found, the cylinder replace (see subsection 9.9).
7. Check existence on brake drums of deep development, cracks, furrows and the painted sites. If it is impossible to remove defects with an emery paper, drums should be removed and pierced in a car-care center workshop (in more detail procedure of repair is described in subsection 9.8).
8. Establish brake drums (see subsection 9.8).
9. Establish wheels and wrap nuts.
10. Clean supports and lower the car.
11. Tighten nuts of wheels with the moment specified in subsection 9.1.

Check of the vacuum amplifier of brakes

PERFORMANCE ORDER
1. Sit down at a wheel and execute the following actions.
2. Stop the engine and press a brake pedal several times. Thus the course of a pedal of a brake should not change.
3. Press a pedal of a brake and start the engine – the pedal of a brake should considerably "leave forward".
4. Press a pedal and stop the engine. Hold a pedal within 30 seconds – the pedal should not утапливаться, be released.
5. Again start the engine and later 2 mines stop. Then again press a brake pedal several times, – the course of a pedal should decrease after each pressing.
6. If the behavior of brakes differs from described above, the vacuum amplifier or needs under repair, or replacement. The order of removal of the vacuum amplifier is described in subsection 9.13.

Hand brake

PERFORMANCE ORDER
1. Slowly lift the lever of the hand brake against the stop and count number of clicks. If the number of clicks corresponds to norm, the hand brake is adjusted correctly. Otherwise the hand brake it is necessary to adjust (cm subsection 9.14).
2. The hand brake can be checked also having established the car on a steep slope, having put it on the hand brake and having transferred a check point control lever to neutral situation. If the car starts to move nakaty, the hand brake it is necessary to adjust (cm subsection 9.14).
