Operation diagram of the pad wear indicator
1. New pad; 2. Worn out; 3. Disk; 4. Indicator; 5. Block
Most vehicles are equipped with a brake pad wear indicator. If you hear a characteristic squealing sound when using the brakes, check the wear of the pads. If the indicator touches the brake disc, the pads should be replaced.

The remaining thickness of the pads can be checked through the window in the caliper (1 – caliper pin, 2 – window).
For a more detailed inspection (uniformity of wear on the plane and checking the condition) the pads need to be removed. The maximum residual thickness of the pads is 1 mm (1983-86) and 2 mm (since 1987).

Removal and installation
1. Raise the front of the car and remove the wheel.

2. Unscrew the lower pin, fold back the caliper and secure it. Do not allow the caliper pin protective grease to be removed or exposed to dirt.

3. Remove the pads, plates and brackets, remember the location of these parts (1 - bracket, 2 - inner plate, 3 - outer plate).
Installation
Correct orientation of anti-noise plates and pads during assembly
1. Inner plate; 2. Inner shoe; 3. Outer shoe; 4. Outer plate
1. Press the piston into the caliper cylinder using a clamp, monitoring the fluid level in the reservoir (when installing new pads, the piston should be retracted a significant distance).
2. Install the plates and brackets in the same order.
3. Install the pads on the caliper. If upper and lower brackets are provided, they should be replaced together with the pads.
4. Install the caliper, wheel and lower the car.
5. Press the pedal several times to press the pads against the disc. Check the fluid level and top up if necessary.
6. Start the engine and press the brake pedal several times again, check the pedal stiffness. During the first 15 km of driving with new pads, avoid sudden braking.
