Product Overview

This high-quality Aftermarket Front Brake Caliper Assy is designed as a compatible aftermarket replacement for Honda PCX125 (2010-2017) models.

The front brake caliper assembly is the hydraulically actuated clamping unit mounted on the front fork of the PCX125, enclosing the brake pistons and pads that squeeze against the front brake disc to generate stopping force when the brake lever is applied. Over time, piston seals can degrade and leak brake fluid, sliding pins can seize from corrosion or contamination, or the caliper body can become physically damaged, all of which compromise front brake pressure, lever feel, and stopping performance. This compatible aftermarket replacement caliper is manufactured to the original hydraulic port, mounting, and dimensional specification of the PCX125, restoring full front brake function and braking confidence.

Complete Part Guide

The Honda PCX125 Front Brake Caliper Assy (45150-K29-D01) is the primary hydraulic component responsible for converting lever pressure into the mechanical friction needed to stop your scooter. For 2010-2017 models, a sticking or seized caliper can lead to dangerous brake drag or a complete loss of stopping power. This aftermarket replacement provides a high-quality alternative to the factory unit, featuring durable seals that resist the corrosive effects of road salt. In stock at Part Hive's London warehouse, complete your order before 1 PM for guaranteed same-day UK dispatch.

We frequently encounter Honda PCX-125 units from the 2010-2017 generation where the front brake caliper has completely seized due to road salt ingress behind the piston seals. In our experience, once the sliding pins become corroded, the caliper can no longer "float" correctly, leading to one pad wearing down to the metal while the other remains untouched. This often results in a terrifying loss of stopping power and a ruined front disc. This performance-grade aftermarket caliper (45150-K29-D01) is a common fix because it's often more cost-effective than trying to hone out a pitted original bore. We suggest technicians always flush the old brake fluid completely when fitting this new unit to prevent old contaminants from damaging the fresh internal seals.
