At work of brake shoes the brake dust which contains asbestos, unhealthy forms. Therefore when cleaning brake shoes do not use the compressed air and do not inhale a dust.


Use of a hammer and the corresponding drift for extraction of pins of fastening of back brake shoes

Removal from a support of the spring which is drawing in brake shoes

Removal of back brake shoes

Replacement of back brake shoes is made similarly, as well as replacement of brake shoes on models with a motionless support with two pistons. Pay attention that sensors of wear of back brake shoes are established only on models with a control system of speed of movement (ASR) (see fig. Use of a hammer and the corresponding drift for extraction of pins of fastening of back brake shoes, Removal from a support of the spring which is drawing in brake shoes).
