KAMIER Brake Caliper Assembly for Razor MX650 MX500 SX500 - Silver Flame, Front & Rear with Pads & Screws

KAMIER front and rear disc brake caliper pads assembly replaces worn brake parts on compatible Razor electric dirt bikes and quads for restored stopping performance.

If your Razor MX650, MX500, SX500, RSF650, or 24V/36V Dirt Quad feels less responsive when braking, worn calipers and pads are a common cause. This KAMIER assembly ships with a flame-style silver caliper, a pair of brake pads, mounting screws, and shims so you can swap both front and rear hardware quickly. The unit is designed to match the original mounting points on several Razor models and similar off-road electric bikes and ATVs.

How will this caliper assembly improve my bike’s braking?

Replacing a fatigued caliper and depleted pads restores bite and modulation, reducing stopping distances and making throttle-to-brake transitions more predictable. New hardware eliminates play from worn components, which reduces uneven pad wear and vibration under braking.

• Includes both pads and shims to ensure correct pad alignment.
• Screws supplied for straightforward bolt-on replacement.
• Front and rear fitment options reduce the need for separate parts.

Which Razor models and vehicles is this compatible with?

This KAMIER assembly is specified to fit a range of Razor electric off-road vehicles and scooters; compatibility covers popular MX and Quad models and certain street and pocket scooter variants. Always verify your vehicle’s brake mounting style and measurements before purchasing.

• Compatible examples: Razor MX650, MX500, SX500, Mcgrath Dirt Rocket Bike.
• Also fits Razor 24V Dirt Quad and 36V Dirt Quad 500 4-wheelers.
• Works with some RSF650 street bikes and 36V Pocket Mod Bellezza scooters.

What’s included and how hard is installation?

The package arrives with a silver flame-pattern caliper, one pair of brake pads, two screws, and two shims—enough to replace a single caliper assembly. Installation requires basic hand tools and a little mechanical familiarity; it’s a direct swap on matched mounts but may need minor alignment and pad bedding.

• Package: caliper, 1 pair brake pads, 2 screws, 2 shims.
• Typical tools: wrench set, hex keys, and a torque driver recommended.
• Post-install: check pad clearance and perform a safe test ride to bed pads.

How long will new calipers and pads last?

Lifespan depends on riding conditions, rider weight, and frequency of heavy braking. Regular maintenance and avoiding prolonged dragging of the brakes extend service life; inspect pads periodically and replace when material reaches the minimum safe thickness.

• Normal urban/recreational use: variable, check every few months.
• Heavy off-road use: inspect more frequently for accelerated wear.
• Replace immediately if you notice reduced braking response or visible pad thinning.

Who is this for: Riders or parents maintaining Razor electric dirt bikes, quads, and compatible scooters who need a straightforward, bolt-on replacement for worn disc brake hardware. This KAMIER assembly suits DIY mechanics who want a complete kit (caliper, pads, screws, shims) to restore braking performance without sourcing multiple components.
