How to Adjust Overly Tight Disc Brake Pads on a Car?
2 Answers
There is a red plastic disc near the spoke side; turning this plastic disc can adjust the tightness. Use the screw on the disc brake caliper to adjust the clearance width. It is recommended that car owners visit a 4S shop or repair shop for adjustment.
Last time my car's disc brakes were too tight, and the brake discs even started smoking—don’t take it lightly. First, park the car on level ground, engage the handbrake, turn off the engine, and shift to neutral to ensure safety. Then, use a jack to lift the wheel, remove the tire, and you’ll see the brake caliper and brake pads. Check if the caliper bolts are loose—if they’re too tight, it’s usually due to stuck bolts or pistons. Prepare a wrench to loosen the bolts slightly, being careful not to remove them completely. Then, gently push the piston back into place or use a flathead screwdriver to pry the brake pads apart and release pressure. After adjusting, reinstall the wheel and test-drive to ensure smooth operation. For tools, use a properly sized wrench and gloves, and lubricating the slide pins is even better. Remember to clean the brake components regularly to prevent dust buildup and seizing. Observe the brakes for a few days after adjustment—if they’re still grinding, take it to a mechanic immediately and don’t risk safety by tinkering further.
