Brake Calipers

Stop Safely with Reliable INFINITI Brake Calipers

Your brake calipers play a crucial roles in your vehicle's performance. That's why regular maintenance is essential. Brake calipers house pistons that squeeze brake pads against rotors. This friction converts your vehicle's momentum into heat, stopping your INFINITI safely. Calipers must function flawlessly for reliable braking performance.

Brake Caliper Mechanics

Calipers contain one or more pistons activated by hydraulic pressure from your brake pedal. These pistons push brake pads against spinning rotors. Seals prevent brake fluid leaks while allowing piston movement. Sliding calipers move on pins to center pressure evenly. The QX50 and Q50 often feature multi-piston calipers for enhanced stopping power.

Why Calipers Malfunction

Brake calipers seize when pistons corrode inside their bores. Road salt and moisture accelerate this corrosion process. Seized calipers cause uneven pad wear and pulling during braking. Leaking seals contaminate brake pads and reduce stopping power. Sliding pins bind when protective boots tear, preventing proper caliper movement. Generic aftermarket calipers often leak shortly after installation. Genuine INFINITI calipers feature corrosion-resistant coatings and precision machining.

Replacement Warning Signs

Replace brake calipers when you notice fluid leaks around the caliper body. Uneven brake pad wear indicates a seized caliper that's not releasing properly. If your vehicle pulls strongly to one side during braking, inspect calipers immediately. Grinding noises suggest complete pad wear from a stuck caliper. Most calipers last 75,000 to 100,000 miles under normal conditions, but inspect them during every brake service.
