The steps to remove the brake discs of a Jetta are: 1. Check the wear degree of the brake discs; 2. Remove the two front wheel tires; 3. Remove the two 18mm screws on the brake caliper and take off the brake caliper; 4. Use a hammer to knock the brake discs off on the front wheel bearings. Taking the 2019 manual basic Jetta VS5 as an example, its front suspension is MacPherson independent suspension, the rear suspension is multi-link independent suspension, it is equipped with a 1.4L turbocharged engine, the maximum horsepower is 150PS, the maximum power is 110kW, the maximum torque is 250Nm, and it is matched with a 5-speed manual transmission.
When working on a car like the Jetta, the first step in removing the brake discs is to safely lift the car using a jack and secure it with sturdy jack stands—never rely solely on the jack to prevent accidents. Next, remove the wheel to expose the brake system, then use a wrench to loosen the bolts on the brake caliper, being careful not to disturb the hydraulic lines. Hang the caliper to avoid any strain on it. Check if there are any retaining screws on the disc; if so, remove them with the appropriate tool. Often, the disc may be rusted in place—I usually spray some penetrating oil, wait a few minutes, and then gently tap the edges with a rubber mallet to loosen it. After removing the old disc, don’t forget to clean the mounting surface and inspect the caliper and brake pads for wear. If you’re installing new discs, it’s a good opportunity to replace the pads as well. The process requires attention to detail, as the discs are easily damaged. When reinstalling, use a torque wrench to ensure the bolts are evenly tightened to avoid affecting braking performance. From my experience repairing many cars, rusted discs making removal difficult is common—applying anti-rust spray beforehand can save a lot of effort.
