Effect of shock wear

The main task of the damper is maintained contact between the wheel (or tire) and the road. Dampers with pneumatic tires and Dynamic Stability Control system, the most important dynamic affecting safety. Their wear has a major impact on comfort and above all safety. Many motorists, however, underestimates the status of your shock!

Wear shock comes slowly and quietly, often not possible for ordinary drivers know if their state has crossed the line when they are excessively worn shock absorbers or even dangerous. The only objective way to assess the effectiveness of shock absorbers is to measure their effectiveness on a special device. Even a layman can not follow the signs that show excessive wear on the shock absorbers. Typical irregularly used as tire wear saw the tread or the flats around the perimeter shell . When an external shock, of course examination shall show no leaks, piston must not be bent or corroded.

What driver risks, if you timely exchange the shock? Wear shock has a negative impact mainly on the car ride. According to the manufacturers is at 50% wear of shock absorbers for a passenger car occupied only by the driver moving on a straight road stopping distance from a speed of 80 km / h by 2.6 meters long and uneven roadway in four people from a speed of 70 km / h even longer 11.3 meters. For cars equipped with ABS extends fifty wear shock braking distances on very slippery surfaces by up to 23% and aquaplaning on the flooded roads with worn shock occurred already at a speed of 109 km / h, while the new speed at 125 km / h The poor state of shock, negatively influence the effectiveness of ABS , traction when starting off, life extension, suspension and tire life. Car tires with 65% efficiency after 9000 show a shock mileage by 10 percent more wear than the car with fully functional devices.

What causes inefficient silencer?
- Lower braking causing extension of stopping distances
- Worse efficiency ABS and ESP - traction impaired during heavy starting or starting off on slippery roads (like axle rebounds)
- Occurs before the aquaplainingu , higher risk of skidding on wet roads
- Reduced handling in cornering, the vehicle is more sensitive to side winds when overtaking
- Affecting ride comfort crew, increased driver fatigue
- Increased tire wear and other parts of the chassis, the tires are small pads
- Oscillating lights

What is the life of shock absorbers?
Shock life depends on the quality of roads on which the car is operated. Generally speaking, after the first 50 thousand should be allowed to check the first shock. Then every 20,000 km. After 60 thousand kilometers we had better think about the exchange!
