How to Replace the Brake Discs on a Nissan Teana?
2 Answers
The steps to replace the brake discs on a Teana are as follows: 1. Check the wear degree of the brake discs. During normal maintenance, brake discs do not necessarily need to be replaced. Determine whether to replace them based on actual conditions. If there are grooves deeper than 3MM on the brake discs, they can be replaced; 2. Remove the front wheel tires. To replace the brake discs, the two front wheel tires need to be removed, revealing the round discs which are the car's brake discs; 3. Remove the caliper mounting bolts. The brake discs are mounted on the front wheel bearings and secured by the brake calipers. Remove the two 18mm bolts on the caliper and take the caliper off. Since the caliper is connected to an oil pipe, lower it slowly to prevent the pipe from breaking; 4. Remove the old brake discs. The old brake discs are mounted on the front wheel bearings, where rust may form between the bearings and the discs. Use a hammer to tap the back of the discs while rotating them to ensure all sides are tapped. After several taps, the old brake discs can be removed; 5. Install the new brake discs. Align the holes of the new brake discs with those on the bearings, then gently tap the inside of the discs with a hammer to secure them firmly onto the bearings; 6. Reinstall the caliper. Mount the caliper back in its original position, tighten the two mounting bolts, and rotate the bearings to check for any abnormal noises.
Last time I replaced the brake discs on my Teana by myself, and the whole process was quite a test of patience. First, you have to safely lift the car, and removing the tires is the most laborious part—remember to prepare a torque wrench and the right socket in advance. When removing the brake caliper, be extra careful with the brake hose; hanging it up with a wire is the safest bet. If the old disc is stuck, you'll need rust remover and a rubber hammer to gently tap it loose. Before installing the new disc, make sure to thoroughly clean the hub mating surface. I skipped this step once, and the result was brake shudder, forcing me to redo the job. Finally, when reinstalling the caliper bolts, follow the torque specifications in the manual—this is one area where you really can't cut corners. During the first week after replacement, try to avoid hard braking to allow proper bedding-in; otherwise, the new discs might develop noise. Doing it myself saved me nearly a thousand bucks, but the sense of accomplishment was even more satisfying than the savings.
