Front brake firm Lucas

1 - the brake hose, 2 - clip 3 - the brake pipe 15 Nm 4 - Self-locking bolt, 30 Nm 5 - a bolt, 12 Nm 6 - the holder of the caliper guide pins and protective covers,

7 - the brake disc, 8 - the brake pads, 9 - heat protection plate, 10 - support, 11 - an arm, 12 - a bolt, 10 Nm
