Removal and installation of a brake disk/support

Rusty brake disks at braking are at the bottom of occurrence of jolting which does not disappear and at long braking. In this case it is necessary to replace brake disks.

Removal

Operation of lifting and car installation on supports is connected with danger! Therefore before operation carrying out familiarise with Razdelom Poddomkrachivanie and towage.

 PERFORMANCE ORDER

  1. Mark with an arrow a direction of rotation of the tyre. Turn away bolts of fastening of a wheel. Lift and establish the car on supports.

Process of removal of supports of different models can have differences. Always it is necessary to replace bolts of fastening of a corresponding support on new since they are self-stopped. Besides, it is necessary to pay attention that bolts of fastening of a corresponding brake disk have the established moment of a tightening.

  1. Back brake: Disconnect a cable of a lay brake from a support, address to Section Removal and installation колодок brake mechanisms of back wheels.

Generally the support can act in film without removal brake колодок.

  1. Turn out bolts of fastening of a support and adhere a wire a support to a suspension bracket.

Do not disconnect a brake hose, otherwise after installation air should be deleted from brake system with application of the special device.

  1. If the support is necessary for removing completely:
  • At a forward support disconnect the brake pipeline in a junction with a hose;
  • At a back support disconnect at first the brake pipeline from a brake hose and then if it is necessary, disconnect a hose at a support.

At opening of brake system the brake liquid follows. Substitute under a following liquid a bottle intended only for a brake liquid. It is possible to suck away preliminary also a liquid a siphon from the tank.

  1. Remove a brake disk.

If the brake disk is supposed to be used further, do not remove it from a nave with force application (hammer blows). For this purpose use rust solvent.

Installation

For achievement of uniform braking from both parties it is necessary to have brake disks with identical quality of a surface. Therefore it is necessarily necessary to replace both brake disks of one axis or to pierce them for one size.

HUNDRED can check up disks on face palpation. The maximum palpation should not exceed 0.05 mm, and the maximum difference in a thickness of a disk should not be more than 0.01 mm.

 PERFORMANCE ORDER

  1. Measure a thickness of a brake disk, address to corresponding Section.
  2. If on a flange of a brake disk and a wheel nave there is a rust, it is necessary for removing.
  3. Clear a thinner a surface of a new brake disk of a sheeting.
  4. Establish into place a support. Depending on the instruction apply new self-stopped bolts. Watch that the brake hose has not been braided. Observe the established value of the moment of a tightening of a corresponding support, address to Specifications.

If the brake hose acted in film, fix it and remove air from system by means of the special device (work HUNDRED).

  1. Observing a rotation direction, establish a wheel. Lower the car on wheels, and only after that tighten fastening bolts cross-wise the moment 120Нм.

Some times standing press a brake pedal so that to feel resistance.

  1. Check up liquid level in the tank, if necessary, add a liquid.

Attention, 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 a brake liquid is filled in?

- On the working engine check up tightness. For this purpose press a brake pedal effort 200 – 300 Н (20 – 30 kg) during 10 with. The pedal should not weaken. Check up all joinings on tightness.

Cautiously allow to be earned extra new brake колодкам. For this purpose some times brake the car since speed 80 to 40 km/hour slightly pressing a pedal. Between braking allow to be cooled to a brake.
