Upgrade Your Bike with Star-Art Front and Back Disc Brake Kit - Aluminum Alloy Calipers, 2 Pcs Stainless Steel 160 mm Rotors & Cable & Brake Lever & 12 Bolts, Freewheel Threaded Hubs Hole Distance of 48mm Review

Everything works fine. The only thing that is repulsive is the build quality, the impression of having just been taken out of the mold and put together straight away.

Abandoned bike shops after too many breakdowns have these brakes fitted in 1 hour and then 30 minutes of riding and adjustment.

This is for a strange application. The rotors didn't match my wheels, the calipers have the smallest pads I've ever seen and the levers really suck. You get what you pay for.

cables for my apartment are rubbish. The calipers work great and so far the salty wind has only ruined the cables. Walmart sells much heavier replacement cables that will work better with these parts.

I thought there was a typo in the description of the 48mm disc brake because I couldn't find a wheel with that geometry. They actually measure 46mm, which means they don't meet the international 44mm standard anyway. Needless to say, my review ends here. I sent them back.

Brakes do not work very well. Firstly the brake discs didn't match my wheels so I had to order all new brake discs, secondly the stopping power of these brakes just isn't there, my old rim brakes on one of my other bikes hold up much better than these. I'll take them off my trail bike and order a better set of brakes.
