Hi my clutch pedal has recently felt like its loosing a lot of pressure especially in the morning . It has a slow leak and iv been topping up the brake fluid and it seems to fix the problem slightly . Today it lost all pressure and I couldn't change gears so I filled it up again, pumped the pedal a couple of times then started it up and this really loud hissing noise was coming out just above the brake pedal in the cabin, sounds like a vacume leak . The noise would only disapear if you step on the brakes or accelerate . The clutch pedal still has not much pressure but the bakes are working fine , just wondering If anyone knows what this might be ?
Thanks
