FEBRUARY 2024 AFTERMARKET 45 www.aftermarketonline.net Juratek Marketing Manager Matt Leeming commented: “The newly released brake discs are all meticulously crafted for precise compatibility with Renault models such as the Megane, Captur, Grand Scenic, Scenic, and Talisman. “In the brake pad category, Juratek presents references specifically designed for the rear of Mitsubishi and Renault models, respectively. These pads join another, which provides front-end service for vehicles such as the Mercedes-Benz X-Class, ensuring a high-performance braking experience. The caliper selection sees the addition of a series suitable for models from Ford and Volvo. This includes EPB calipers, featuring a 38mm piston diameter for optimal pressure distribution. “Complementing the range are brake shoes for models such as the Hyundai Sonata and Toyota 4 Runner. For hydraulic systems, brake hoses are now available, extending Juratek's offerings to Mazda 3 and CX-5. The latest range expansion also introduces wheel cylinders for Hyundai and Kia models. Lastly, the new range includes wear leads designed to fit BMW models.” Matt added: “Juratek offers technicians downloadable troubleshooting guides, technical bulletins and posters that can be printed out and displayed in the workshop for helpful tips and tricks.” For more information, visit: www.juratek.com Extreme loads With van deliveries a fact of life for households and businesses alike, many garages will be seeing LCVs that are doing very high mileages coming through the doors on a regular basis. On what to look out for, Elisa Röhl, Head of Product Team Brakes/Drivetrain at MEYLE observed: “Light commercial vehicles are frequently exposed to extreme loads. Taking transporters as an example. They often operate day and night. Sometimes as delivery vehicles, sometimes in the commercial sector, transporting goods or tools from A to B. Therefore, the brake pads are exposed to high weight masses and continuous stress as they are used a lot. This often leads to rapid wear, frequent replacement and thus a decreased service life, to name just some of the consequences.” She continued: “In the last couple of years the aftermarket resorted to normal brake pad compounds which were unable to meet the high demands on braking performance, heavy loads and mileage at the same time. So how can one ensure that the vehicles can cover these important tasks reliably and, above all, safely? Because let’s be honest; The number of vehicles used to transport and deliver goods won’t decrease with the constant rise in e-commerce and people ordering more online. “It is essential that the brake pad compound is designed to fit the vehicle precisely. Matching the friction partner of the brake disc is also an integral part. A brake pad needs the right materials as well. In order to significantly increase the service life of the brake pad, we at MEYLE for example, developed a special friction lining compound which is optimized against rapid wear. They wear off more slowly, ensuring a longer service life and running time between pad changes. This allows transporters to withstand the heavy loads of daily transport, delivery and commercial use. “The brake pad compounds should be free of copper and heavy metals as well, so that it meets the requirements of worldwide regulations that reduce or completely ban the residual amounts of copper, metal, heavy metal and asbestos in brake linings. The brake pads should be of high quality right from the development stage too, and the entire development and manufacturing process should be continuously monitored.” Elisa added: “For light commercial vehicles in particular, it is important to ensure that the brake pads are of highquality materials and fit precisely in order to extend the time between maintenance interval, allowing the vehicle to be used for longer without downtime.” Brembo tech tip; Avoiding brake squealing Brembo’s UK & Ireland Key Account Manager Siti Abdullah said: “Brake squealing is a result of vibrations within the braking system and there can be myriad causes for it. Luckily, brake squeal-ing can be minimised and eliminated if the mechanic uses good quality components, the correct tools and takes the necessary preventative maintenance steps.” Starting with the discs, Siti said: “Evaluate both the disc condition and its thickness. Minimum thickness is generally marked on the rim of the braking surface or on the hub surface. Replace if the discs are below minimum thickness. Check the discs per axle at each change of pads for grooves and cracks. Again, if necessary, replace the disc.” On cleaning, she said: “Clean the disc with either petrol, spirits or a specific brake disc cleaner. This includes cleaning the braking surface and the surface that comes into contact with the hub. The anticorrosion layer must be completely removed. If the disc is a coated disc, it is not necessary to clean the braking surface.” On the hubs, she observed: “Always clean the surface of the hub before installing a new disc.” You also need to check for runout: “Always measure the disc before and after maintenance, using an appropriate tool. Ensure that runout does not exceed 0.10mm when the disc is fitted, as runout variation is a common cause of brake vibration.” Then there are the pads: “Always check the pads’ thickness and surface. Replace the pads if necessary because pads that are below specifications can result in safety and noise issues like cracking and fading.” On directional pads, she noted: “When fitting the pads inside the caliper body, ensure they are being installed in the correct direction, which can be indicated by the presence of arrows, the letters L for left and R for right, a crescent or half-moon cut-out on the anti-noise shim, or differentiated chamfers on the pads themselves. Siti added: “After any braking replacements, mechanics should carry out a road test and then advise the driver to bed-in their new system for around 200 miles.”
