just tips to know if my motorcycle brakes is still in good condition
you will know when they are no good......its called lack of brakes
Visually inspect your pads to be sure. Anything more than 50% wear, I would replace.
Does it STOP well? 80% of braking is done with the front wheel. The rear brake isn't as powerful but should be noticeable when you apply the frake.
Compared to what? Not clear your frame of reference, or context of the question. How did they behave when new? Any mushiness at all in the lever, or pedal, would be cause to take action. Fortunately, usually the fix is quite simple. Bikes are great to work on, everything is right there. Consult a torque table for proper values on the caliper bolts. Remove the bolts, and calipers, and examine the pads directly. If they are thin, replace them. If not, don't. This is not a bad thing to do occasionally, on general principles. Pretty simple, and doesn't require exotic tools other than the basics plus the shop manual and torque wrench. I personally would NOT want to mis-torque a caliper bolt... Bleeding the brakes systems on most bikes requires clear tubing, brake fluid, 8mm socket, and little else. A rubber mallet to tap the calipers (to drive out air bubbles) doesn't hurt. Takes less than 30 minutes per caliper, details can be found elsewhere. I used to do this at least seasonally on all my bikes. ABS, LBS, and similar complicate the situation somewhat.
Front discs, you can actually see the pads. Same goes for rear disc brakes rear drum brakes, there is a pointer that is almost accurate on the rear brake arm flush your brake system and add dot 5... nice firm brakes
