11.2. Replacement of brake shoes

It is necessary to replace brake shoes in pairs, i.e. on both wheels of one axis. Replacement of brake shoes of the parking brake is described in the Section Replacement of Brake Shoes of the Parking Brake and Their Razzhimny Mechanism.


 PERFORMANCE ORDER

  1. Remove wheels.

Models with floating supports (forward wheels)

 PERFORMANCE ORDER

  1. Remove the holding spring (1). At the left separate the socket of the sensor of wear of brake slips, if necessary replace the sensor.
  1. Remove plastic caps (2) and take out a brake hose from the holder. Twist the directing fingers located under caps and remove a support, having pulled it back.

At installation clear (but do not grease!) the directing fingers, check a condition of a carving and if necessary replace fingers.


  1. Move the piston as it is possible further in the wheel cylinder. For this purpose it is possible to use, for example, adaptation No. 34 1 050.

When moving the piston you watch the level of brake fluid and do not allow transfusion it too much the tank.

  1. Remove an external brake shoe. At the same time the clamping spring holds an internal block on the piston. Mark the earned extra blocks and do not confuse them with unilateral wear. Clear brake shoes.

You do not apply lubricant on a back plate of a block.


  1. Check a boot (1) for absence of damage and if necessary to replace it. Clear a contact surface (2) pistons of the brake cylinder and apply on it a thin film of the paste preventing squeal of details of the brake mechanism.

Do not allow contact of paste with a boot as it can bulk up under its influence.


  1. Clear the interfaced surfaces of T-shaped zaversheniye of brake shoes and the case of a support and grease them with a thin layer of the paste preventing squeal of details of the brake mechanism.
  1. Installation is made upside-down.
  2. Upon termination of works several times squeeze out a brake pedal that brake shoes reached working position of rather brake disks.
  3. At installation of new brake shoes on forward and back wheels bring the level of brake fluid to the mark "MAX".
  4. Hold the ignition key not less than 30 with in situation "1", without starting the engine. Thereby the code of malfunction is removed and repeated inclusion To/L wear of brake slips is prevented.

Models with motionless supports (forward wheels)

 PERFORMANCE ORDER

  1. Separate the socket (1) sensor of wear of brake shoes, take out the directing fingers (2) and remove the holding spring (3).
  1. Take brake shoes by means of a stripper No. 34 1 010. Mark the earned extra blocks and do not confuse them with unilateral wear. Clear brake shoes.

Do not allow contact of paste with a boot as it can bulk up under its influence.


  1. If blocks are jammed, beat out them by means of special adaptation No. 34 1 000.
  1. Displace the piston as it is possible further in the wheel cylinder by means of adaptation No. 34 1 050.

When moving the piston you watch the level of brake fluid and do not allow transfusion it too much the tank.

  1. Clear guides of brake shoes of a support, check boots for absence of damage and, if necessary, replace boots.
  2. Installation is made upside-down.

You do not apply lubricant on guides of brake shoes and the contact surfaces of the piston of an aluminum support of Brembo.

  1. Perform the operations described in paragraphs with 8 on 10.

Models with floating supports (back wheels)

 PERFORMANCE ORDER

  1. Remove plastic caps (1). At the left separate the socket of the sensor of wear of brake slips, if necessary replace the sensor.
  1. Twist the directing fingers located under caps.

At installation clear (but do not grease!) the directing fingers, check a condition of a carving and if necessary replace fingers.


  1. Remove the holding spring (3) and a support, having pulled it back.
  1. Perform the operations described in paragraphs with 3 on 10.
