NICHE Brake Rotor
A brake rotor is what your vehicle’s brake pads clamp down on to stop the wheels from spinning.
Brake rotors are the circular discs that are connected to each wheel. Rotors are designed to turn motion (kinetic energy) into thermal energy (heat)
Just like brake pads, brake rotors wear down every time you apply the brakes. On average, rotors can last anywhere from 30,000 to 80,000 miles
NICHE Brake Caliper
Where?
- 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.
