Car: 1997 a4 1.8t sport avant
After having a full load in the car at the weekend I thought the brakes were particularly bad (worse than usual). When i got home i checked the resivoir as I got the brake light warning on the DIS, to find the fluid was at a level just below min. I topped it up and pumped the pedal a few times and it pretty much just dropped to the floor with constant pressure.
I'm leaking fluid from the N/S/R caliper, i took the wheel off and had a quick look but I couldnt really see where it was coming from (the dripping stopped by the time i moved from the car to the rear wheel). The flexi-hose its self didnt look perished and the banjo bolt at the union was tight but it seemed to be coming out somewhere near this joint.
Is this a common problem on the rear?
Is this likely to be the caliper or the hose?
