K i got a 89 cherokee 4 door 4.0L auto well the brakes on front and rear have all fully been replaced including hardware we did all the brake bleeding and all that to front to rear made sure it had all the air out well now when i push on the brakes the barely work and then the pedal pauses and if you push harder it completly locks up the rear tires ONLY then once you let off the pedal the tires roll like normal well on my way home the other night it did it again this time i caught in the corner of my eye that the brake light for the emergency brake came on i thought that was weird since the emergency brake wasnt even touched if anyone has any idea what it could be it would help alot thanx
