Brake Hardware: the small parts that keep the big brake parts honest

Brake hardware is everything that mounts, locates and secures your rotors, pads and calipers so the assembly stays quiet, square and torqued. That means rotor bolt kits with T-nuts, disc hat adapters, bobbins and wear plates, anti-rattle shims, and anchor rods. Skip it and a rotor floats on its hat, a pad squeals against a caliper, or a bolt backs out under heat cycling. When you fit a new rotor or swap a caliper, the correct hardware is what makes the install torque up right the first time.

What ThreePiece stocks

This category runs 70 products from 10 brands, priced from $17 to $229 for what is currently in stock (that range moves as stock changes). Wilwood is the deepest at 40 of the parts sampled, followed by PowerStop (8), Brembo (6), Performance Machine (5) and Bikers Choice (4), with TwinPower, Goodridge, ProTaper, EBC and Alcon filling out the rest.

Concrete examples show the spread. The Wilwood Rotor Bolt Kit - Dynamic Front 12 Bolt with T-Nuts and the Wilwood Hat-BB Front .750in Offset cover big-brake mounting. The Brembo Disc Hardware Pack H-Bobbin With Wear Plates sits near the top of the range at $228.72, while the Brembo Hardware Pack for 365x34/380x34mm Rotors handles floating-disc rebuilds. For quieting a pad, the EBC Racing Front Titanium Shim for the Subaru WRX STI, and for motorcycle work the Performance Machine Steel Anchor Rod Assembly 6in.

How to choose

Hardware is not one-size. Buy to match the part it serves. If you run a floating big-brake disc, you need the bobbin or hardware pack sized to your rotor - the Brembo packs above are split by rotor diameter, and one is listed partial without bushings, so read the description before you order. If you are bolting a hat to a rotor, the bolt kit and hat have to match your bolt circle and offset, which is why the Wilwood hat lists its 4 x 3.93 pattern and .750in offset in the name. If your only complaint is noise, a shim like the EBC titanium unit is the cheap fix long before you replace anything larger.

What else you need with it

Hardware is almost never the whole job. Pair it with Brake Rotors and Brake Pads, and if you are moving up in stopping power, look at Brake Upgrade Kits or Brake Calipers. Rebuilding hydraulics alongside? See Caliper Rebuild Kits and Brake Lines. Everything lives under the main Brakes section.

Fitment and ordering

Of the parts here, 14 carry specific fitment data spanning model years 1982 to 2024, with coverage seen on Harley-Davidson, Ram, Ford, Dodge, GMC, Subaru and Jeep - including the Ram 3500, Ford F-450 Super Duty, GMC Sierra 3500 HD and Subaru WRX STI. Many hardware parts are sold by dimension rather than by vehicle, so confirm your rotor and caliper specs before buying. Not sure? Call fitment help at 813-535-5801 or use our contact page. All orders ship free, and Affirm and Katapult financing is available at checkout.
