It‘s got 8500 miles on it.When its moving , lets say when I push it I hear scratching I think it‘s the breaks because the sound is kinda similar to a sound a car makes when a brake job is needed.I tested the brakes they hold perfectly. Does this mean I need new brake pads? How can I troubleshoot this and know what it is that I need?Thanks in advance :)
I would bet you need a brake job right now. Look at and feel the rotor (round thing that the pads are against ) and if you have any groves in it . If you do , park it
There are two things you should check. First, the brake pads. Normally a bike will still stop with wore out pads but to know the condition for sure you should try to look at the pads while standing in line with the bike. If they appear to have less than 1/8 inch between the steel outer part of the pad and the rotor they are shot. Secondly, the rotors may have gotten hot at some point and may be out of round. The only real test you can do at home is feel the rotors for deep ridges. If they are grooved they may need replaced. A local bike shop (non-dealer) would normally charge $45 plus parts to change both front and rear pads and check your rotors.
One of the advantages of a hydraulic disc brake system is that it's self-adjusting. On the downside, this nicety often makes it hard to determine if the pads are worn without physically inspecting them. One indicator of pad wear is the fluid level in the master cylinder. As the pads wear the caliper piston moves farther out in its bore. Fluid from the master cylinder must then fill the space behind the piston. The first clue that the pads need an eyeballing may be a drop in the brake-fluid level. Typically, brake pads will have some sort of visual indicator to let you know how much life is left. These may be painted strips, slots cut into the pads or a step milled into the pad material. As the pad wears, so do the indicators. When they disappear, it's time to replace the pad. Some manufacturers may specify a minimum thickness for the pad material. In most instances this is somewhere between 2.0 and 1.5mm. The wear indicators are visible without removing the pads from the caliper, though you might need to remove an inspection cover to see them. I'm not sure on the GSXR's. If you wait until you can hear the metal against metal grating of the pads grinding through the rotor, and assuming you get the bike stopped without hitting whatever it is you're trying to avoid, consider the pads and rotors trashed beyond redemption.
