Hesterberg-Cad/Cam Rear Brake Caliper Bracket 84mm Quick-Change System – Kawasaki ZX-10R (2021–2026)

Machined from aerospace-grade aluminium 7075-T6 to tolerances that matter at race pace, the Hesterberg-Cad/Cam 84mm rear brake caliper bracket is a purpose-built quick-change component for Kawasaki ZX-10R riders who demand pit-lane efficiency without compromising structural integrity. Every gram saved and every surface finished speaks to the precision CNC process behind it.

Key Features

• CNC-machined from aluminium 7075-T6 for an exceptional strength-to-weight ratio at approximately 0.225 kg
• 84mm mounting pitch accommodates a wide range of aftermarket brake calipers — CNC-machined calipers strongly recommended for tightest fitment tolerances around the wheel hub
• Threaded interfaces allow connection to the chain tensioner, holding the caliper securely in position during rear wheel removal and eliminating the risk of pads slipping or the caliper dropping
• Drilling position sketch included, supporting accurate installation by experienced workshop personnel
• Available in natural or black anodised finish — both offer corrosion resistance suited to track environments
• Compatible with ZX-10R models 2011–2020 when the ABS sensor is upgraded to the 2021+ unit (Plug & Play per manufacturer)
• Supplied with all required mounting hardware

Build Quality and Materials

Hesterberg-Cad/Cam designs and manufactures this bracket using 7075-T6 aluminium — the same alloy grade favoured in motorsport and aerospace applications where load-bearing precision is non-negotiable. The CNC milling process ensures every mounting surface and threaded bore meets tight dimensional tolerances, which is critical when pairing the bracket with aftermarket calipers that must clear the wheel hub without rework.

The natural anodised finish preserves the raw machined aesthetic while offering a hardened surface layer, while the black anodised variant delivers a clean, understated look equally at home on a paddock-prepared race machine. Neither finish adds meaningful weight, and both contribute to the bracket's long-term durability under repeated heat cycling.

Designed for Fast Rear Wheel Changes

On a trackday or in a race paddock, time spent swapping tyres is time lost on track. The conventional approach — removing the rear caliper entirely during a wheel change — introduces two risks: pads can migrate out of position, and a heavy caliper can be dropped, damaging pads or the caliper body itself. The Hesterberg-Cad/Cam quick-change system addresses both.

By threading the bracket directly to the chain tensioner, the caliper remains correctly located throughout the wheel removal process. The rear wheel slides out cleanly, the tyre is changed, and the wheel is reinstalled with the caliper already in its correct position. The result is a more controlled, faster, and consistently repeatable pit stop routine — exactly the marginal gain that separates relaxed tyre changes from unnecessary delays in the box.

Why an Aftermarket Caliper and Not the OEM Unit?

The OEM Kawasaki rear caliper design means brake pads can fall free during wheel removal, turning a straightforward job into a time-consuming retrieval exercise. A compatible aftermarket caliper with the 84mm bolt spacing retains pads more reliably throughout the process. Hesterberg-Cad/Cam specifically recommends a precision CNC-machined caliper over cast alternatives: cast calipers carry larger manufacturing tolerances that can create clearance problems around the wheel hub, potentially requiring remedial machining. With forged wheels, the manufacturer confirms that any compatible caliper can be fitted without modification.

Fitment & Compatibility

This rear brake caliper bracket is designed for the Kawasaki ZX-10R from model year 2021 to 2026. It is also usable on ZX-10R and ZX-10 RR models from 2011 to 2020, provided the ABS sensor is exchanged for the 2021+ version — which fits the earlier models on a Plug & Play basis according to the manufacturer. The 84mm bolt pitch is compatible with aftermarket calipers sharing that centre-to-centre spacing; CNC-machined calipers are recommended for the most straightforward installation.

Installation and Usage Notes

• No type approval or road-use certification — track use only
• Not approved for use on public roads
• A new brake line is required upon installation
• Installation by qualified workshop personnel is strongly recommended
• A drilling position sketch is included to assist with accurate fitting
• Product images are for illustration; delivered item may differ slightly in appearance
