Rear Brake Backing Plate w/ Bearing & Seal – Fits Honda TRX300 / TRX300FW 1988–2000 – OE‑Spec Replacement

OVERVIEW

This rear brake backing plate restores essential stopping power and safe deceleration by providing a rigid mounting surface for drum brake shoes on Honda ATVs. Machined from heavy-gauge steel to OE specifications, the component delivers consistent braking performance while resisting warping under repeated thermal cycles. It is engineered specifically for Honda TRX300 and TRX300FW four-wheel-drive motorcycles and off-road machines.

ENGINEERING & PERFORMANCE

The reinforced steel housing maintains precise alignment for brake shoe engagement, delivering predictable lever feel and reduced mechanical drag compared to fatigued factory units. High-density steel construction resists heat fade and corrosion, extending service intervals even when operating in muddy or wet conditions. The bearing and oil seal arrive pre-pressed into the casting, guaranteeing a clean install that blocks dirt intrusion and simplifies rear-wheel teardown.
