Attention! The pads are changed only as a set per axle.
1. Raise the car, remove the front wheels.
2. On some vehicles, pry up and remove the brake pad wear sensor by disconnecting the wires (see photo).
3. Perform the actions illustrated in the photo.
4. Check the residual thickness of the friction material of each pad. If there is wear or damage, or if the thickness of the friction material is below the permissible limit, replace the pads (see photo). The pads should be replaced if they become oily.
5. If the condition of the pads is satisfactory, clean them. Wipe the contact areas of the pads with the caliper body and bracket.
6. Check the free movement of the bolts in the caliper guides. Check the condition of all rubber boots, the presence of leaks from the cylinder. Apply copper-based grease to the metal plate of the pad (see photo). If the pads are changed, the pistons should be inserted into the cylinders. For this, either a special device or a clamp is used (see photo). As you insert the pistons, remove excess fluid from the reservoir.
7. Assembly is performed in reverse order. First install the inner shoe, then the outer shoe. The outer shoe has an audible wear indicator (see photo).
