The brakes then began to feel very different two hours into the journey. At one point the pedal virtually went to the floor when normally the pressure on the pedal is pretty hard. I was wondering if the high temperatures can affect the brake fluid? The brakes have been back to normal since. I have not done any extended drives since nor has the engie been quite so hot.
Any ideas before i take it to the garage?
Had a very similar pedal to the floor experience on a longish journey not long after I got this car. The rear brake cylinder was stuck and heated the fluid. There was very little drag noticeable just by pushing/rocking the car. Only really noticeable by spinning the wheel off the ground.
