Brake system

Before coming to final conclusion about existence of problems with the brake system make sure that tires are in satisfactory condition and are beefy with the required pressure (The head Nastroyki and routine maintenance), adjustment of angles of installation of forward wheels is not broken and the car is not loaded unevenly.

The car when braking "takes away" 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 (The head the Brake system).
  2. Excessive wear of frictional material of overlays of blocks/boots of the brake mechanism from one of car boards takes place (The head the Brake system).
  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 the required effort fixture (The head Podvesk and steering).
  4. Assembly of a drum/support of one of brake mechanisms is faulty. Remove a drum or a support and check it for existence of signs of jamming of the piston and other damages (The head the Brake system).
  5. Rams of floating brackets of a support of the forward disk brake mechanism are unevenly greased. Remove a support and grease rams (The head the Brake system).

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

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

The course of a brake pedal is excessive

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

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

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

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

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

The pedal utaplivatsya to a floor with the minimum resistance

  1. As a result of leakages of the wheel cylinder(s), pistons of a support(s), weakening of fastening, a rassoyedineniye or damage of brake lines, etc. of 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 are worn-out (The head the Brake system).

Brake pedal pulsations when braking the car take place

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