Brake Component Kits

About Brake Component Kits

A brake rotor kit with bracket packages a rotor with the bracket that mounts it, so the parts arrive as a matched set. Riders choose one when they want a different rotor size or style and do not want to hunt for the pieces separately.

Every listing in this category is a rotor kit with a bracket, and the titles name the main choices. Rotors come as solid mount or floating, and in 270 mm and 280 mm diameters. A solid mount rotor is fixed to its carrier. A floating rotor is attached so that the rotor can move slightly on the carrier, which allows for heat expansion. Each listing says which machine it is for, so confirm that first, and make sure your caliper suits the rotor size.

All of the products here come from GBrakes. A new rotor and bracket works with the rest of the brake system: Brake Disc Rotors, Brake Calipers & Brackets and Brake Pads. Fit the pads that suit the caliper and follow the maker's instructions for bedding in. For a fit check, read why parts don't fit. The whole group is Brakes & Brake Parts.

FAQs on brake rotor kits

What is in a brake rotor kit with bracket?

It is a rotor and a bracket sold together as a set. The listing title gives the rotor size and whether it is solid mount or floating, and the description lists the bike it fits. Read what else is included before ordering.

What is the difference between a solid mount and a floating rotor?

A solid mount rotor is fixed to its carrier as one piece. A floating rotor has a carrier with the braking ring attached so it can move slightly, which lets it expand with heat without distorting. Both are listed by size.

How do I choose between a 270 mm and a 280 mm rotor?

Choose the size the listing gives for your machine. If you are changing from the stock size, confirm that the caliper, bracket and wheel all suit the new diameter before you order.

Should I change the pads when I change the rotor?

Usually yes. Pads that have worn in against an old rotor may not seat well on a new one, so fit new pads unless yours are nearly new. Clean the new rotor with brake cleaner, then bed in the brakes as the pad maker instructs.
