       NOTE
Surely you make replacement of all blocks of one axis of the car even if the limit of wear was reached by only one block. If blocks are repeatedly established, before removal they need to be marked.

turn off two bolts of fastening of a support to the holder of a support. Pay attention that bolts of fastening of a support самоконтрящиеся and have various length;
disconnect the holder of a brake hose from a rotary fist;
