What to Do When the Brake Disc Has Bulges?
3 Answers
Brake disc bulges are caused by severe wear of the brake disc. The solutions are as follows: 1. If the condition is not too severe, the owner can take the vehicle to a repair shop to have the brake disc polished. 2. If the brake disc is severely worn, it needs to be replaced with a new one. Relevant information about the automotive braking system is as follows: 1. The automotive braking system mainly consists of brake pads, brake discs, brake linings, vacuum booster pumps, master brake cylinders, and brake calipers. When the brake pedal is pressed, the master brake cylinder pushes the brake calipers through brake fluid, and the brake calipers then clamp the brake discs with the brake pads. 2. The brake caliper is the brake cylinder, which contains pistons. The brake fluid in the braking system needs to be replaced regularly. Brake fluid is a liquid that easily absorbs moisture. If the moisture content in the brake fluid is too high, it can lead to reduced braking force and extended braking distance, which affects safety.
I enjoy working on my car myself, and when I encounter issues like raised spots on the brake discs, I don’t immediately head to the repair shop. First, I check if the brake pads are unevenly worn or if there’s debris stuck, as this is often the root cause of the raised spots. I use calipers to measure the thickness of the brake discs. If they’re still within the resurfacing range, I’ll handle it myself with a grinding tool, saving a few hundred bucks. But remember, minor raised spots can be smoothed out by grinding, while severe ones require replacing the discs. Otherwise, you’ll experience brake shudder and noise while driving, which compromises safety. I regularly clean the brake system to prevent dirt buildup. When working on it yourself, be careful not to grind the discs too thin—if they fall below the manufacturer’s minimum thickness, they must be replaced. Never compromise on this. After handling it this way a few times, my car’s braking performance has been quite stable, and I feel a real sense of accomplishment.
I've been driving for over 30 years and seen too many similar issues. Raised spots on brake rotors are no small matter - they're usually caused by uneven brake pad wear or poor-quality materials. If left untreated, they can cause brake wobble at high speeds, increasing accident risks. My advice is to stop and inspect immediately. If the raised spots aren't too deep, just have them professionally resurfaced at minimal cost. For deeper grooves, replace both rotors and pads to avoid higher repair costs later. I always say regular maintenance is key - inspect your brake system every six months to prevent raised spots. Safety comes first; don't delay repairs to save money until accidents happen. I've accumulated plenty of experience through decades of driving, and everyone should stay vigilant.
