Rear Brake
« on: December 15, 2016, 09:44:28 AM »
When I brake hard with my rear brake in the Cforce 550 you can hear some sort of loud clicking knocking noise. Doesn't happen with the front brakes though. On a YT video i saw an X8 braking hard and I could clearly hear the same sound. Does anyone know what I'm talking about, what is that noise? Is it like that in every model? :)

I'm not sure if the CFMoto has one or two calipers on the rear axle.  My Polaris Sportsman only has 1 caliper.  Loud clicking occurs when braking as it transmits braking force through the axles and CV joints.  Polaris machines are notorious for it.  My Sportsman did it since it was new.

Yeah CFM has a one piston caliper on the rear and a two piston caliper on the front. All too small..imo. Many CVT type drivetrains make a lot of noise within the transmissions to the axles when the brakes are applied while decelerating in 2wd. If you put it into 4wd and do the same thing, many report a reduction in the noise. If this is true with yours, that's probably what it is. But if no change, better take a closer look at things like caliper bolts, rotators, knuckle and a-arm bolts and bushings and even wheel bearings.

It sounds to me like it would be normal noise due to the hard braking on the rear, which is connected to the driveline, this will create lash in the driveline if you are on the brink of locking up the rear tires, the may be locking up for a split second then getting traction and spinning again which is making the driveline go slack then have tension again, done in rapid succession will make a lot of noise. I got this in my Polaris and even on my dirt bike.

Yeah, mine has been doing it since New too. Seems like it's something "normal" :D Thanks for the answers guys!
