Принцип дії

The disc brake caliper is a fundamental component of your vehicle's hydraulic braking system. When the brake pedal is pressed, hydraulic pressure from the master cylinder forces pistons within the caliper to clamp the brake pads against the rotating brake rotor. This friction converts the vehicle's kinetic energy into heat, slowing and stopping the vehicle. The Mercedes-Benz 166 421 01 81 Disc Brake Caliper is engineered to provide precise and consistent braking force, contributing to the overall safety and control of your vehicle.

Технічне обслуговування

Regular inspection and maintenance of your braking system are essential for safety and longevity. While the caliper itself is a durable component, its proper function relies on the condition of surrounding parts.

• Гальмівна рідина: Check brake fluid level and condition regularly as per your vehicle's service schedule. Brake fluid should be replaced periodically.
• Гальмівні колодки: Inspect brake pads for wear during tire rotations or at least annually. Replace pads when they reach their minimum thickness.
• Brake Rotors: Check rotors for excessive wear, scoring, or warping. Replace or resurface as needed.
• Перевірка супорта: During brake service, inspect the caliper for leaks, seized pistons, or damaged guide pins. Ensure guide pins are properly lubricated.
• Гальмівні магістралі: Inspect brake lines for cracks, corrosion, or leaks.

Always use genuine Mercedes-Benz parts and approved brake fluid for replacements.

Troubleshooting Common Brake Issues

If you experience any of the following symptoms, it is crucial to have your braking system inspected by a qualified technician immediately.

• Симптом: Squealing or grinding noises during braking.
  Можлива причина: Worn brake pads, foreign object, or caliper issue.
• Симптом: Vehicle pulls to one side when braking.
  Можлива причина: Uneven brake pad wear, seized caliper piston, or contaminated brake fluid.
• Симптом: Soft or spongy brake pedal.
  Можлива причина: Air in the brake lines, low brake fluid, or master cylinder issue.
• Симптом: Pulsating brake pedal or steering wheel vibration during braking.
  Можлива причина: Warped brake rotors.
• Симптом: Brake fluid leak.
  Можлива причина: Damaged brake line, caliper seal, or master cylinder.

Do not attempt to drive a vehicle with compromised brakes. Seek professional assistance.
