Good quality. Delivered Early!

My 2007 Grizz had been sitting for quite some time and brake fluid was NASTY! Changed fluid and rebuilt rear caliper and master cylinder. Parts for both were bought from Motosport. The reason for only 4 stars is that the master cylinder kit did not contain the 2 screws for the reservoir cap. Really could have used the replacements. Other than that the parts were excellent! The early delivery was a pleasant surprise!

Made my brakes like new again

I bought this for a 2000 kx125 and there was an overlap in part numbers that year so initially I got the wrong kit. Motosport took care of it promptly and updated their catalog info.

Right fit

Bought this rebuild kit for my rear brake master cylinder and it fit perfect, all the parts where correct and good quality also, glad I was able to find it and fixed it for cheap, way less than what a new cylinder would have cost.

Fit on 09 crf150r

Glad I purchased this kit because my brakes would work after bleeding them but then once I started to ride after about 20 or 30 minutes the brake pedal would go all the way down and no breaking action. This kit fixed my problem

It broke installing

The main seal ripped on installation and i did not get all the parts it show i get 2 new screws and mine came with out any screws. Also my box was wrecked on arrival. And my paper work was just crammed in the box.the delivery guy drops it on my porch rings the bell and just about ran off.watch him do it on my cameras.

Pretty minimal kit

Kit contained the bare minimum components. Had the 2 top screws, circlip, 2 plunger orings and brass fittings for the line, but not the top diaphragm, plunger, interior plastic fitting. It was sufficient, but not the pleasant surprise you get with kits from a company like Moose - perhaps this is the norm for brake kits? Will probably try another brand next time to see.
