Need to describe what problem your having??? At times the ABS sensor's get knocked out of alignment which will cause your ABS light to come on. The other thing also if you use a different type of brake pads such as metallic compared to ceramic brake pads.
I had brake problems (locking up when starting up) that led me to new rotors and pads (88k on my Canyon). Didn't help. Seemed better for a day or two and now it's back to locking up every time I start out after its been setting overnight or its wet outside. Don' know what to do next.
