Description
Product Overview
The M MATI rear brake caliper assembly is engineered specifically for a wide range of Polaris off‑road motorcycles, delivering a direct‑fit solution that replaces the original equipment without modification. Each unit arrives pre‑matched with high‑quality brake pads, ensuring the caliper and pads work together as a calibrated system. This eliminates the guesswork of mixing components and guarantees the braking performance expected from OEM parts. The assembly conforms to the exact dimensions and mounting points of the original Polaris design, making it a seamless swap for owners seeking dependable stopping power.
Constructed from a robust aluminum alloy housing and hardened steel pistons, the caliper offers an optimal balance of lightweight handling and long‑lasting durability. The alloy resists corrosion in harsh environments, while the precision‑machined pistons provide smooth, consistent pressure across the pad surface. Internal seals are crafted from high‑temperature resistant polymers, protecting the hydraulic system from fluid leaks and extending service intervals. Every component undergoes strict quality control to meet M MATI’s standards for strength, heat dissipation, and wear resistance.</n
Performance testing on a variety of terrain—mud, sand, rocky trails, and steep descents—demonstrates the caliper’s ability to maintain stable brake modulation and reduce fade under repeated heavy use. The integrated pads are formulated with a composite material that offers high friction coefficients while remaining gentle on rotors, helping to preserve rotor life. In laboratory brake dynamometer trials, the assembly achieved stopping distances comparable to factory‑installed units, confirming its suitability for both recreational riders and competitive racers.
Compatibility spans multiple Polaris models, including the Magnum 325 (2000‑2001), Magnum 500 (1999‑2001), Scrambler 400 (1998‑2002), Scrambler 500 (1998‑2004), Trail Blazer 250 (1999‑2004), Trail Blazer 400 (2003), Trail Boss 325 (2000‑2002), Trail Boss 330 (2003‑2004), Xpedition 325/425, Xplorer 250, and SPORT 400. The part numbers 1910691, 1910449, 1910367, and 1910270 are all covered, ensuring that owners of older and newer models can source a single, universal solution. This breadth of fit reduces inventory complexity for dealers and simplifies the buying process for end users.
Installation is straightforward: the caliper mounts to the existing bracket using the original bolts, and the included pads slide into place without the need for additional hardware. A brief torque check and a bleed of the brake line complete the setup, allowing riders to return to the trail within minutes. The package is shipped in a compact, protective box that safeguards the components during transit, and the included instruction sheet provides step‑by‑step guidance for a hassle‑free upgrade.
M MATI stands behind its products with a dedicated service team ready to address any concerns. Should a defect arise, the company offers a replacement or repair under its standard warranty, reinforcing confidence in the durability of the caliper assembly. Customers can also access technical support for installation tips, brake fluid recommendations, and routine maintenance advice, ensuring the brake system remains at peak performance throughout its service life.
Usage
Designed for the demanding conditions of off‑road riding, this rear brake caliper excels on muddy tracks, sandy dunes, and rocky mountain paths where reliable braking is essential. Riders who tackle steep descents will appreciate the consistent pedal feel and the ability to modulate braking force without sudden lock‑up, enhancing control and safety on technical sections. The assembly’s heat‑resistant design also helps dissipate energy during prolonged braking, reducing the risk of fade during long downhill runs.
Beyond extreme sport, the caliper serves daily commuters who rely on their Polaris for work or errands. The dependable stopping power translates to confidence in urban traffic, wet pavement, and stop‑and‑go situations. Because the pads are pre‑matched to the caliper, brake response is predictable, allowing riders to brake earlier and smoother, which can improve overall ride comfort and reduce wear on other suspension components.
Regular maintenance is simple: inspect the pads for wear every 500 miles, check the hydraulic fluid level, and look for any signs of leakage around the piston seals. When pads reach the minimum thickness, replace them with the same OEM‑fit set to maintain optimal friction. The aluminum housing requires only occasional cleaning to remove dirt and debris, ensuring the caliper continues to operate without corrosion or binding.
Why Choose Us
M MATI has built a reputation for delivering high‑quality motorcycle components that meet or exceed original equipment standards. The company’s engineering team works closely with manufacturers to understand the precise tolerances required for each model, resulting in parts that fit perfectly the first time. This commitment to precision reduces the need for aftermarket modifications, saving time and money for both dealers and riders.
Each caliper assembly adheres to OEM specifications, meaning the geometry, piston size, and mounting points are identical to the factory part. This ensures that the brake system’s balance remains unchanged, preserving the handling characteristics that riders expect from their Polaris. The inclusion of matched pads further guarantees that the braking surface is optimized for the caliper’s piston travel, delivering consistent performance from the moment of installation.</n

FAQ
Is this caliper compatible with my 2003 Polaris Trail Boss 330?
Yes. The M MATI rear brake caliper assembly is listed as compatible with the Trail Boss 330 model years 2003‑2004, and it uses the same mounting hardware as the original part.
Do I need to replace the brake fluid when installing this caliper?
While it is not mandatory, we recommend flushing and refilling the brake fluid with fresh DOT 4 fluid during installation to ensure optimal hydraulic performance and to remove any contaminants that may have accumulated.
How often should the brake pads be inspected or replaced?
Inspect the pads every 500 miles or after any hard braking event. Replace the pads when the friction material reaches the minimum thickness indicated on the pad surface, typically around 2 mm.
Can I install the caliper myself, or do I need a professional mechanic?
The caliper is designed for a straightforward bolt‑on installation. If you have basic mechanical skills and the proper tools, you can complete the swap yourself. However, a professional mechanic can ensure the brake system is properly bled and calibrated.
What warranty does M MATI provide for this brake caliper assembly?
M MATI offers a one‑year limited warranty covering defects in materials and workmanship. If a problem arises within the warranty period, contact our support team for a replacement or repair.
