M MATIRear Brake Caliper Assembly for Polaris Magnum 325 500 Scrambler 400 500 Trail Blazer 250 400 Trail Boss 325 330 Xpedition 325 425 Xplorer 250 SPORT 400 with Pads 1910691 1910449 1910367

Good price and fit perfect on my 99 polaris magnum 500 4x4. My old mounting bolts threaded right in with no issue, easy to install. Comes with new brake pads already installed and an extra bleeder valve. I would reccomend this caliper if you're looking for one, and I'll likely end up purchasing again in the future as I'm always buying and fixing atvs.

Easy to install, and Easy to bleed. Gravity bleed first.

Another piece of off shore junk brought to you by Amazon. Completely worthless waste of time, now I have to machine the casting to fit to OEM spec, the casting was left rough cast where it mounts to the caliper bracket and not properly spot faced to spec. Who knows what Chineseum crap is inside this thing. This definitely DOES NOT fit a 2001 Polaris Magnum 325 4x4

Be careful with the bleeder valves they seem to strip or snap easy and I'm barely using any Force there aluminum so be careful but this is my third rear brake caliper from three different places they all seem to be the same

Had one bleeder bushing shear off after installing it and bled the brakes. Contacted Mati and they shipped a new caliper within four days. Also searched the reviews and noticed that eight others had the same issue. Not sure the issue is cheap brass or over tourquing when installed. Caliper fit great in a 2003 Polaris Trailblazer and for the price was a good value. Keeping fingers crossed it won't happen again but great customer service!!!!!!

It fit well and works good.

Fit is off a little bit. Front bolt hole had to be grounded off an eighth of an inch in order for disc brake pads to line up properly. Easy to do with grinder. This was on a 2001 Polaris 325 Magnum 4x4. But it seems to be good otherwise.

Fit perfect and great price, bleeders are very fragile so I broke one but they included a second so all good

2001 Polaris Xplorer, fit was perfect, easy bleed and works as expected

This replacement caliper was advertised to fit my application, however it is a tad tight on the inner side and not centred like the old one. Not sure whether to shim the brake disc out or shave some material off of the caliper to obtain proper fitment. The disc does turn, and there is braking effect. 8/10 was expecting better from a quality name like Mati.
