first, look for fluid leaking. If a caliper failed, you have no pressure. If a cylinder failed, you may have little or no pressure. If you have no leakage, try this.
make sure the M/C reservoir is full. crack the lines coming off the M/C one at a time and apply brakes. you should have a solid stream of fluid expel. if no pressure or just a dribble of fluid, you have a M/C problem. If you have good pressure there, bleed the cylinders/calipers. if there is no pressure at wheels, you have air in lines or contamination most likely. you may also pinch the hoses to block flow to cyls/calipers, and see of the pressure holds. if the pads are too low, you can over extend or even blow a caliper piston from it's housing. Sometimes, a brake pad may even fall out and cause the caliper to over extend or fail. if the caliper is at fault, suggest replacing in pairs.
Hope this may help.
