Assuming the fluid level in the master is still good, take a pair of pinch–off pliers and pinch off the Flex hose that joins the rear breaks to the frame. Pump up the brakes. Is the pedal now firm and not leaking down? If yes, then the problem is in the rear. Remove the wheels and inspect the rear drums, shoes and wheel cylinders, or inspect the Rear Rotors, pads and calipers. Repair, remove and replace the items needed to restore the system to OEM specs and serviceability. If pinching off this hose made no change, then leave the hose pinched off and then continue to diagnose the system. Follow the lines along the frame back up to the master and try to notice any signs of obvious leakage. | Assuming the fluid level in the master is still good, take a pair of pinch–off pliers and pinch off the Flex hose that joins the rear breaks to the frame.

Check the level of the fluid and pump up the brakes. Is the pedal now firm and not leaking down? If yes, then the problem is in this caliper. If the wheel is still on, remove the wheel and inspect this caliper and surrounding structure. Repair, remove and replace the items needed to restore the system to OEM specs and serviceability. If one caliper is bad expect to do both as the brakes should always be done as a set. |

If after all this and the pedal still will not pump up or hold a pedal, re-inspect all the lines from the master to the flex hoses, use a flash light if needed to inspect the lines running along the frame and again look for leaks and signs of leakage. | If after all this and the pedal still will not pump up or hold a pedal, re-inspect all the lines from the master to the flex hoses, use a flash light if needed to inspect the lines running along the frame and again look for leaks and signs of leakage. | ||
