Brake system

Before coming to the final conclusion about existence of problems with brake system make sure that tires are in a satisfactory condition and are pumped up with demanded pressure (Head of Control and routine maintenance), is not broken adjustment of corners of installation of forward wheels and the car is not loaded non-uniformly.

The car when braking "withdraws" in one of the parties

  1. Blocks/boots of the brake mechanism from one of car boards are damaged or polluted by oil. Check a condition of blocks/boots (Head Brake system).
  2. Excessive wear of a frictional material of overlays of blocks/boots of the brake mechanism from one of car boards (Head Brake system) takes place.
  3. There was a weakening of fastening or a detachment of components of a suspension bracket. Check a condition of support of components, tighten with demanded effort fixture (Head the Suspension bracket and a steering).
  4. Assembly of a drum/support of one of brake mechanisms is faulty. Remove a drum or a support and check it on existence of signs of jamming of the piston and other damages (Head Brake system).
  5. Are non-uniformly greased ползуны floating brackets of a support of the forward disk brake mechanism. Remove a support and grease ползуны (Head Brake system).

Extraneous sounds (high-frequency squeal) take place when braking car

  1. Blocks of disk brake mechanisms are worn-out. Squeal is published by sensors of excessive wear of blocks at a friction about a brake disk (are established not on all models). Similar squeal arises also at a friction about a disk of a material of a substrate of a block at a full wipe of a frictional slip (if sensors are not provided). Immediately replace blocks (in both mechanisms) (Head Brake system). If overlays of blocks are completely wiped it is necessary to check also a condition of brake disks (Head Brake system).
  2. Insulators of brake shoes (disk mechanisms) are lost or damaged. Replace insulators (Head Brake system).
  3. Frictional slips are polluted or greasy. Replace blocks/boots.
  4. Slips not that type are established. Make replacement.

The course of a brake pedal is excessive

  1. Partial refusal of brake system. Check all system (Head Brake system), make necessary corrections.
  2. Level of brake liquid in the main cylinder is insufficient. Check level (Head of Control and routine maintenance), in case of need make having added and pump over system (Head Brake system).
  3. Adjustment of back brake mechanisms is broken. Make a series of braking at car movement by a backing. If it does not help malfunction elimination, remove drums and check a condition of mechanisms of self-regulation (Head Brake system).

When squeezing a pedal of a brake there is a feeling of softness of a course

  1. Air got to hydraulic system. Pump over brakes (Head Brake system).
  2. Flexible brake hoses are faulty. Check a condition of all hoses and system lines. In case of need make replacement of components.
  3. Weakened fixture of the main brake cylinder.
  4. The main cylinder (Head Brake system) is faulty.

For braking of the car it is necessary to make excessive effort a pedal

  1. It is faulty the vacuum amplifier of brakes (Head Brake system) functions.
  2. Blocks/overlays of boots of brake mechanisms are excessively worn-out. Check, in case of need make replacement (Head Brake system).
  3. One or more pistons of supports or wheel cylinders are jammed. Check, make necessary corrections (Head Brake system).
  4. Frictional overlays of blocks/boots are polluted by oil, greasing or brake liquid. Check, in case of need make replacements (Head Brake system).
  5. New blocks/boots are established and were not earned extra yet. For their extra earnings to disks/drums some time is required.

Pedal утапливается to a floor with the minimum resistance

  1. As a result of leakages of the wheel cylinder (ов), support pistons (ов), weakening of fastening, a rassoyedineniye or damage of brake lines, etc. violations liquid level excessively fell in the tank of the main brake cylinder. Check all system, make necessary corrections.
  2. Sealing cuffs of the main brake cylinder (Head Brake system) are worn-out.

Pulsations of a pedal of a brake take place when braking car

  1. The support does not move properly as a result of the wrong installation or obstacle existence.
  2. Remove and make check (Head Brake system).
  3. The disk or drum is faulty. Remove (Head Brake system) and check on existence of excessive cross-section palpation, and also emergence of ovality and not planeness. Make a disk or drum pro-point or replace them new.
