Sven Nielsen, Technical Director from MEYLE, says the following difficulties may arise with the Peugeot, Citroën and Toyota:
Defective wheel bearings
Loud metallic rolling noises are indicators of defective wheel bearings. Increased wheel bearing tolerances can also be diagnosed by tilting the wheel while the car is not under any strain. In order to prevent more serious damage or the complete loss of the wheel bearing, the driver should seek the assistance of a repair garage as soon as possible.
In the event of a defective wheel bearing, MEYLE in-house engineers recommend to always also check the other axle bearings because it has to be presumed that all wheel bearings are exposed to the same stressors and are thus likely to have similar life spans.
To be able to warrant optimum repair results, MEYLE also keeps complete MEYLE wheel bearing sets in stock. These kits contain all of the essential installation materials, e.g. locking nuts and screws, lock washer, lubricant grease and other components that are relevant for repairs. Hence, repair garages can forego time-consuming individual orders that would otherwise have to be issued for the necessary installation materials.
At MEYLE, wheel bearings are produced in close cooperation with the company’s engineers. Thanks to the use of high quality materials, strict compliance with the production tolerances and the in-house quality assurance management at the headquarters in Hamburg, these safety relevant MEYLE brand components ensure the vibration free operation of the wheel and of the brake discs throughout the long life of these components.
A proper professional installation of the wheel bearings and the wheel hubs in the axle stubs according to the manufacturer’s recommendations are also of crucial importance to get the maximum life span out of these components.
Damaged shock absorbers
Many car drivers lack awareness of the vital role shock absorbers play for overall car safety. The parts wear away gradually, many defects are not visible at first glance, but their impact on the overall car system is dramatic. Properly functioning shock absorbers reduce braking distances, ensure excellent roadholding when cornering and trouble-free operation of state-of-the-art driver assistance systems such as ABS, ESP or TCS.
With high-quality shock absorbers from MEYLE for the Peugeot 107, Citroën C1 and Toyota Aygo from 2005 on independent workshops are well equipped for the repair of these safety-critical components. Even when exposed to highest stress, MEYLE shock absorbers ensure an enhanced driving experience: when braking, cornering or riding along bumpy roads. They excel because of the excellent piston rod sealing and their vehicle-specific damping characteristics.
MEYLE also offers rubber buffer (bump stops) and dust cap kits optimally geared to each shock absorber, complemented by a range of strut mounts.
Defective or porous brake hoses
Defective or porous brake hoses and the prevalent hygroscopic conditions may allow moisture to penetrate the brake system. This causes the brake fluid’s boiling point to fall, facilitating the formation of vapour bubbles in the brake system, which may cause the brakes to fail completely under strain. Brake hose swelling is another risk factor. The cross-section becomes smaller; in the worst-case scenario, the hose may act like a valve. The brake pressure is transported to the brake calliper or brake cylinder but can no longer be released once the pedal is released.
Brake hoses are responsible for transporting brake fluid and thus maintaining pressure levels inside the brake system. They should be checked regularly for tears and bulges.
Only a few drivers are aware that brake hoses should be replaced every four or five years, as the rubber and fittings frequently become brittle after a few years. If a brake hose falls out of a brake circuit, the second brake circuit is usually efficient enough to stop the vehicle. However, if both brake circuits fail, there is hopefully enough time for the driver to get the situation under control by using the engine or hand brake.
MEYLE brake hoses help keep drivers safe. MEYLE’s high-quality brake hose portfolio covers more than 23,000 vehicle applications in all established European and Asian models. The program is continually being expanded. All MEYLE brake hoses are made to OEM standards and manufactured in Europe in close collaboration with the engineers at the company’s headquarters in Hamburg. The high quality of the material used is proven by subjecting the hoses to a pressure of 900 bar. The rubber of MEYLE brake hoses is DOT and SAE J 1401 approved.
MEYLE also supplies complete brake hose sets to achieve optimum repair results. This saves workshops from having to place time-consuming separate orders of essential parts. The sets contain all the banjo screws and copper gaskets required for certain vehicle applications. MEYLE in-house engineers recommend the installation of new gaskets every time the brake hose is changed and, because they are so critical for vehicle safety, only to have them replaced by trained specialists.
