Brake Discs, Rotors & Hardware for GMC Acadia

Discs, Rotors, and Hardware for GMC Acadia

As a cross-over SUV, the GMC Acadia is designed to handle all types of driving conditions. Understanding how the braking system operates and what products are available to meet your expectations goes a long way to providing you the comfort you deserve when taking your vehicle out for a spin. When necessary, you can find discs, rotors, and hardware to implement upgrades and repairs.

The Acadia disc braking system begins to function the second that you press the brake pedal. This pressure signals the master cylinder to send pressurized fluid to the calipers located at each wheel of the vehicle. Pistons within the calipers are forced outward from the force of the fluid which squeezes the brake pads against the rotors’ surfaces. The car then slows down or comes to a stop, depending on the pressure you apply.

There are two types of calipers installed in GMC automobile braking systems. These caliper options are the floating and standard designs. Floating calipers sit on pins located at the brake rotor. The design of these components allows the caliper to move from side-to-side along the rotor for optimal braking capabilities. Standard calipers are mounted to a stationary area near the rotor.

Brake dust shields are installed between the rim of your vehicle and the rotor. Usually made of aluminum, these shields protect your all-wheel drive SLE-1 or SLT-1 Arcadia SUV from the dust created by the disc during braking. These accessories prevent brake dust from setting on the rim or from disrupting standard braking capabilities.

There are three main types of brake pads made for the GMC disc braking system. These include ceramic, semi-metallic, and non-asbestos.

• Ceramic: These pads are made of ceramic materials which are bonded with copper fibers and heated to create a hardened product.
• Semi-metallic: These pads are made from metal fibers such as copper, brass, and steel. When combined with resin, the pads are durable and can handle all types of driving conditions.
• Non-asbestos: These pads are made from natural products such as rubber, glass, and Kevlar. These pads are bonded with resin for durability.

No. There are three types of rotors manufactured for the GMC Acadia. These include standard, slotted, and drilled rotors.

• Standard: Standard rotors on the Arcadia have a flat solid surface that allows the pads to grab without causing skipping or hesitation during braking.
• Slotted: Slotted Arcadia rotors have slits on the surface that act as vents. These slits allow gases and heat created while braking to flow away from the braking system and its components.
• Drilled: Drilled rotors have holes drilled into their surfaces to cool the brakes.
