What Is the Brake Caliper?
Most vehicles feature disc brakes on the front wheels, with many also equipped with disc brakes on the rear. The brake caliper is an essential component of the disc brake system. When you press the brake pedal, brake fluid flows from the master cylinder to the calipers. This fluid pressure pushes pistons inside the caliper, forcing the brake pads against the rotors to slow or stop the vehicle. Depending on your vehicle’s setup, it may have two or four calipers. Calipers are exposed to high heat during braking, which can degrade seals and cause fluid leaks. At Nationwide Mechanics, we connect you with skilled mobile mechanics who provide professional brake caliper inspection and replacement services at your convenience.
Keep in Mind
Brake caliper servicing often involves replacing brake pads as well, since worn calipers usually coincide with worn pads.
How the Service Is Performed
- Remove and replace brake calipers and brake pads
- Inspect brake rotors for wear or damage
- Inspect brake lines and hoses for leaks or deterioration
- Replace brake fluid as needed
- Check the brake system for leaks
- Bleed the brake system to remove air
- Torque wheels to manufacturer specifications
- Test brake system performance for safety and reliability
Our Recommendation
Follow your manufacturer’s recommended brake service intervals. Driving with worn brake pads or rotors can damage calipers and compromise braking. Regularly change brake fluid (approximately every 30,000 miles) to maintain system integrity. If you notice clear fluid on your wheels or driveway or experience softer brake pedals, have your brake system inspected promptly.
Common Symptoms Indicating Brake Caliper Replacement
- Unusual squealing or grinding noises when braking
- Vehicle pulling strongly to one side during braking
- Spongy or soft brake pedal that travels further than usual
- Visible brake fluid leaks around wheels or on the driveway
Importance of This Service
Maintaining fully functional brakes is critical for your safety. Ignoring minor brake issues can quickly lead to costly repairs and unsafe driving conditions. Prompt caliper replacement and brake maintenance ensure reliable braking and peace of mind on the road.
