Well mondeo mk2 went in for its mot today and failed on one thing. The ns front brake hose was twisted and rubbing in some bit of metal. So hubby removed front calliper and untwisted it and put it back on. Ten min job and it was sorted or so I thought. Now the brakes are spongy and pedal touching the floor. Didn't remove hose so assume it didnt need bleeding plus the system was bled a few days ago. Did it anyway and one tiny bubble came out. Brakes still spongy and not a clue why. Any suggestions?
