A brake caliper straddles each rotor in the front, which is mounted to the wheel hub How many? While many ATVs have 4 brake calipers, 1 for each wheel, it is not uncommon for an ATV to have only 3 calipers. How it works? When the brakes are applied, brake fluid is pushed from the master cylinder to the caliper piston. The force of the brake fluid causes the piston to apply pressure to the brake pads, which then squeeze the rotor. The friction and heat created by the brake pads on the rotor creates a drag on the rotor NICHE Brake Caliper Mounting Bracket Purpose of a brake caliper mounting bracket? - Designed to keep your caliper in the right position Can a caliper mounting bracket go bad? - The brake caliper pin can slide into a bore in the bracket, the rubber boot can fail and allow water or other outside dirt into the bore, causing corrosion and binding. What does a loose caliper sound like? - A loose caliper will move around and make a clicking sound that comes from the wheel. Each brake has a backing plate that if bent inward will rub against the rotor or caliper and create a clicking sound.

Some common materials used in organic brake pads include glass, fiber, rubber, carbon and Kevlar. Semi Metallic Semi Metallic Pads are the most versatile style available, with the slight compromise being more noise and dust. They are also longer lasting and more durable, and their metallic composition can help draw heat away from the rotor and aid in more efficient brake cooling. Ceramic Ceramic Pads are composed of a dense ceramic material with embedded copper fibers. In use since the 1980s, ceramic pads were developed as an alternative replacement for organic and semi-metallic brake pads. Ceramic pads are generally easier on rotors than semi-metallic pads. Good Soft, quiet, easy on rotorsDon’t require much heat to generate good frictionProduce less dust than metallic pads Bad Only operate well within a relatively limited temperature rangeWear out quickly compared to other types of brake pads Good Dramatically increased braking performance over organic padsHave a higher thermal threshold due to metallic contentHave a wider operating range (temperature)More resistant to brake fade than organic pads Bad Tend to be noisier than organic or ceramic padsProduce more brake dustMore abrasive than other types of pads – will wear brake rotors more quickly Good Quieter than semi-metallic pads – emit noises that are above the range of human hearingLonger lifespan than organic or semi-metallicStable under a wide range of temperatures for consistent performance Bad Typically the most-expensive type of brake padDo not produce as much cold bite as semi-metallic pads – may not be ideal in extremely cold climatesDo not absorb heat as well as semi-metallic pads which can increase brake system temperatures
