DescriptionThe whole story▼
The Accossato PZ017 is a radial caliper built for the rear wheel of Mini GP machines and pit bikes, with a 45 mm distance between mounting centres and a 29 mm offset. This listing is the die-cast version, built with two stainless steel pistons at 24 mm diameter and finished in black rather than the hard-anodised look of the CNC-made version. No dust seal is fitted, and the two AGPP258 pads supplied come in a sintered compound as standard on this version, rather than as a choice made at checkout. For a rear caliper that mostly needs to do its job without fuss, the die-cast build keeps the specification simple.
Key Features
- Radial rear brake caliper, 45 mm mounting centres, offset 29 mm
- Die-cast manufacturing
- Two pistons, 24 mm diameter, stainless steel
- No dust seal fitted
- Black die-cast finish
- Two brake pads, code AGPP258, included, sintered compound
- Also built as a CNC version with aluminium pistons
Construction and Material Quality
Accossato builds the PZ017 in two manufacturing versions that change both the piston material and the finish together. This listing is the die-cast version: the body is cast rather than CNC-machined, the two pistons are stainless steel rather than aluminium, and the finish is black rather than the natural hard-anodised look used on the CNC version. Neither version carries a dust seal, which is typical for a rear caliper of this size on Mini GP and pit bike applications, and both take the same AGPP258 pads.
The Die-Cast Version: Stainless Pistons, One Pad Compound
Choosing the die-cast PZ017 settles two things at once rather than one: the pistons are stainless steel instead of aluminium, and the pads fitted come in a sintered compound rather than being offered as organic or sintered depending on preference. That makes this version a simpler purchase for a rear caliper that is not expected to need a different compound later, since the sintered mixture already covers consistent grip across hot, cold and wet conditions. The 45 mm mounting centres stay the same as on the CNC version, so the two manufacturing versions are interchangeable on the bike itself, and the choice comes down to piston material, pad compound and finish rather than fitment.
Fitment and Compatibility
The PZ017 is sold as a universal rear caliper for Mini GP and pit bike conversions rather than against a named machine list, so the 45 mm mounting centres, 29 mm offset and rear disc thickness already fitted should be checked before ordering, along with whether a caliper adapter is needed for this manufacturing version.
Road Approval
Accossato does not provide ABE documentation for the PZ017, and Mini GP machines and pit bikes built for competition are generally used off the public road in any case; where a conversion is intended for road use, it needs to be cleared with a registration authority beforehand. Fitting and bleeding the caliper should be left to a qualified workshop.
