Disc brakes
1. Pads can be checked through a window in the caliper (indicated by an arrow).
2. Measure thickness (A) friction linings, and if the thickness is less than specified in subsection 2.1, then replace the pads.
4. If there is any doubt about the normal condition of the pads, then the pads should be removed.
5. At the same time, check the condition of the disk. Measure the disc thickness and check the surface condition. If the thickness is less than normal, then replace the disc. Minor surface defects are removed by grinding, a badly worn disc should be replaced.
6. Check for fluid leakage from the hose at the indicated location (arrow) and hydraulic brake lines. Check connections for tightness. Repair any defects found immediately.
Drum brakes
1. Take off the drums (see subsection 8.6).
2. Check the thickness of the friction linings. If their thickness (or distance to rivet heads) less than 1.6 mm, or there are signs of oiling or serious damage, replace the pads.
3. Check up a condition of springs and a backlash regulator between pads and drums.
4. Check for fluid leakage from the wheel cylinder by opening the dust cover. If a leak is found, replace the cylinder.
5. Check the condition of the drums. Sand small defects with sandpaper, if necessary, grind the drums.
6. Install all removed parts and lower the vehicle. Tighten the wheel nuts to the specified torque.
Checking the vacuum booster
1. With the engine off, press the brake pedal several times, the brake pedal travel should not change.
2. Step on the pedal and start the engine, all the time. After starting the engine, the pedal should move forward a little.
3. Press the brake pedal and stop the engine. For about 30 seconds, the pedal should hold its position.
4. Start the engine again, after 1 minute stop and press the pedal several times. The pedal travel should decrease with each press.
5. If the operation of the vacuum booster differs from that described above, then the vacuum booster must be replaced in this case (see subsection 8.13).
Checking and adjusting the hand brake
1. Move the transmission lever to the neutral position. Applying moderate force to the handbrake lever, count the number of clicks of the full travel of the lever. If the number of clicks is not correct, then the handbrake must be adjusted.
2. Check the operation of the handbrake by driving the vehicle on a steep slope. The adjustment procedure is described in subsection 8.11.
