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.
Organic
Organic Pads are composed of various fibers mixed with binding resins to hold them together. 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.

Fit like a glove. The mounting brackets had different size bolt holes, so I needed to use my old ones.

Perfect fit. Great product. Be careful bleeding the bleed valve is weak. But I was using a ratchet instead of a wrench so could have been my fault. But either way perfect description and perfect fit. 2005 Ranger 500 4x4
