How many brake pads does one wheel have?

Each tire requires 2 brake pads, meaning a total of 8 brake pads are needed for a car. Below are the replacement criteria for brake pads: 1. Mileage: Under normal driving conditions, front brake pads should be replaced every 30,000 to 50,000 kilometers, and rear brake pads every 60,000 to 100,000 kilometers. If severe wear is detected, immediate replacement is necessary. 2. Wear level: New brake pads are typically about 1.5 centimeters thick. If the thickness wears down to one-third of the original or less than 5 millimeters, it is recommended to replace them promptly. If a metallic scraping noise is heard during braking, this may indicate that the brake pads have worn down to the minimum thickness, and the limit indicators on both sides are making contact with the brake disc, producing abnormal sounds—immediate replacement is required. If the brake pedal feels lighter than usual, or if braking becomes difficult or ineffective, this suggests that the brake pads are severely worn and no longer thick enough, necessitating immediate replacement.

Speaking of how many brake pads per wheel, I've driven quite a few cars myself, and generally there are two brake pads per wheel. Why two? It's related to the design of the brake caliper. The caliper acts like a clamp, gripping the rotating brake disc, with one brake pad fixed on the inside and another on the outside. This setup provides greater friction when clamping, resulting in better braking performance. Most modern cars use disc brakes, with one caliper and these two pads per wheel. For older drum brakes, they don't use brake pads but rather brake shoes, though those are becoming increasingly rare. Driving habits also affect lifespan—frequent hard braking wears the pads faster. Remember to check the thickness every 20,000 kilometers or so. For safety, if the thickness is below 3 millimeters, replace them immediately—don't skimp and take risks. Always replace them in pairs to avoid imbalance.

In automotive braking systems, disc brakes are the mainstream, with each wheel corresponding to a brake caliper that houses two brake pads: one inner and one outer. This design ensures even force distribution for stable braking. Brake pad materials, such as ceramic or semi-metallic, affect noise and performance and wear down over time. If you hear squeaking or notice softer braking, the pads may be thinning and need inspection. For regular sedans, front and rear pad wear is similar, but rear-wheel-drive vehicles experience faster rear pad wear. Replacing brake pads is affordable, costing a few hundred yuan per set, but don’t overlook routine maintenance. Safe driving tip: Minimize frequent braking in traffic jams to extend pad lifespan. Remember to schedule regular brake system maintenance to prevent accidents.

Bro, simply put, a wheel usually has two brake pads. Most cars now have disc brakes, with two pads installed on each caliper per wheel. If you feel the brakes are weak while driving, it might be because the pads are worn and need replacement. During maintenance, the mechanic will check the thickness and replace them if they're below the standard. Safety first—don't delay. Always replace pads in pairs. It's a small cost you shouldn't skimp on.
