Warning! The brake pads must be replaced on both front/rear brakes at the same time. Remember that the dust generated during the operation of the brake mechanisms may contain asbestos, which is extremely harmful to human health. Never blow off dust with compressed air or inhale it - wear a protective mask or respirator when servicing mechanisms. Never use gasoline or petroleum-based solvents to clean brake system components - use only branded cleaners or methyl alcohol!
The procedure applies equally to both front and rear disc brakes.
1. Remove the cap from the brake fluid reservoir.
2. Loosen the nuts on the respective wheels. Jack up the front/rear of the vehicle and place it on jack stands.
3. Remove front/rear wheels.
Note. All four brake pads on both wheels of the same axle must be replaced at the same time. To avoid confusion, work with each mechanism individually.
4. Carefully inspect the brake disc (see Section Check of a condition, removal and installation of a brake disk). If it is necessary to perform a groove, remove the disk.
Front wheel brakes
1. Using a clamp, press the piston into the caliper cylinder, thereby providing the necessary free space for installing new pads that are thicker. When the piston is sunk into the caliper, the liquid level in the GTZ reservoir will rise - make sure that it does not start to overflow, pump out the excess if necessary.
2. Before dismantling the components, be sure to wash them with a special cleaner. Then follow the instructions in the illustrations below.
Rear wheel brakes
1. Wash the brake assemblies with a special cleaning compound. Then proceed according to the instructions given in the illustrations below, then proceed to the procedure described in paragraph 1 below.
2. Coat the back of the new pads with a special anti-squeal compound. Instructions for using the product are usually printed on the wall of the can.
3. Install shims on your pads.
4. Install the shoe holders into the caliper anchor bracket. Lubricate the shoe holders with a thin coat of high temperature grease.
5. Install new brake pads with shims in the caliper anchor bracket.
6. Using needle-nosed pliers, rotate the piston, sinking it into the caliper cylinder in order to provide the necessary free space for installing new brake pads.
7. First, sink the piston to the bottom of the cylinder, then turn it back so that, when installing the inner shoe, the protrusion on its back side falls into one of the selections on the end surface of the piston. Make sure that the piston boot is not deformed as a result of the rotation of the piston.
Brakes front and rear wheels
1. Replace the wheels, lower the vehicle to the ground and tighten the wheel nuts to the required torque (see Specifications to Chapter Settings and ongoing maintenance).
2. Depress the brake pedal/cock the parking brake lever several times (when changing rear pads) in order to shrink the pads on the disc.
3. Check the brake fluid level, correct if necessary (see chapter Settings and ongoing maintenance). Before starting the normal operation of the vehicle, make sure that the braking system is working properly.
