How to Disassemble the Verna Brake Disc?
4 Answers
1. Check the wear level of the brake disc. During routine maintenance, the brake disc does not necessarily need to be replaced. Determine whether to replace it based on actual conditions. If there are grooves deeper than 3MM on the brake disc, it can be replaced. 2. Remove the front wheel tires. To disassemble the brake disc, first remove the two front wheel tires, and you will see the round disc, which is the car's brake disc. 3. Remove the caliper mounting bolts. The brake disc is mounted on the front wheel bearing and secured by the brake caliper. Remove the two 18mm bolts on the caliper and take off the caliper. Since the caliper is connected to an oil pipe, lower it slowly to prevent the oil pipe from breaking. 4. Remove the brake disc. The brake disc is installed on the front wheel bearing, and rust may form between the bearing and the brake disc. At this point, you can use a hammer to tap the back of the brake disc while rotating it to ensure all sides are tapped. After several taps, the brake disc can be removed.
I've done the job of removing the Hyundai Verna's brake discs a few times myself. First, find a safe, flat area, lift the car with a jack, and place bricks behind both rear wheels to prevent rolling. Then, use a wrench to loosen the wheel nuts but don't remove them completely, take the wheels off and set them aside. Next, handle the brake caliper by using a socket wrench to remove the bolts securing it, being careful not to damage the brake lines, and hang the caliper on the side of the brake with a metal hook. The next step is to remove the retaining screws on the back of the brake disc—usually two—they might be rusted, so apply some WD-40 for lubrication. After removal, check the disc surface for obvious wear or scratches and take the opportunity to clean the caliper bracket. Before reinstalling, ensure the new or cleaned disc aligns with the holes, and don't overtighten the screws. The whole process takes about an hour, and you'll need all the right tools, including a torque wrench to prevent stripping. I always test drive for a few rounds to ensure the brakes are working properly before driving with confidence.
As a car owner who just started DIY, I once removed the Verna's brake discs and advise beginners not to rush. First, prepare tools like a jack, safety stands, wrenches, and sockets—safety comes first, and operate in a garage or ventilated area. The steps are: lift the car securely, remove the tire and set it aside, then loosen the brake caliper bolts to detach the caliper and hang it without pulling the brake line. Use the right tools to remove the brake disc mounting screws. Note that the disc might be rusted onto the hub—tap the edges gently to loosen it but avoid forcing it. After removal, check if the brake pads need replacement and clean off dust and debris. Don’t rush the process; inspect each step to ensure the right tools are used to prevent damaging screws. The whole process isn’t complicated, but safety is paramount. My first time took over two hours with extra care, and I tested the brakes afterward to ensure performance was fine.
To save money, I decided to remove the Verna's brake discs myself, avoiding repair shop fees. The process starts with jacking up the car, removing the wheels, then detaching the caliper and unscrewing the bolts to take off the disc. Basic household tools like wrenches and a jack are sufficient, costing just a few hundred yuan. The key is choosing the right time for replacement, such as when the disc surface is worn to its limit, preventing later issues like noise or vibration. During the process, check the disc thickness and caliper slide conditions, addressing any rust promptly. DIY saves nearly half the cost compared to shops but takes time—I spent a weekend morning on it, also picking up some basic mechanical knowledge. Beginners should consider asking a friend for help, ensuring steps are memorized to avoid rework and waste.
