Hi All, This forum and others has given me some information but hoping someone can give me more information. Pressing brake pedal; seemingly operates as normal but maybe 3/4 of its full distance is stiffens up (ie. more than you would expect). This is only really noticeable when you're driving at high speed and need to stop or slow down in a short distance. Main issue seems to be the slow return of the brake pedal. It does return fully, but takes a few seconds to do so. Brake light remains on and brakes do seem to be 'dragging'. Will then release. Had the car in the garage for something different. They had a quick look and said discs, pads and calipers seem ok but will get it up in the air and check properly. I've been warned that it (hopefully) could be something simple such as split hose or in worst case scenario could be knackered servo. I trust the guys (used them for years) but they are not Audi specialists. They reckon that if it was a replacement servo that it might be an engine out job, which is probably not going to be cheap on a 3.2 quattro. I'll be getting it back in at the end of the month for more investigation, tyres, service and all being well an MOT. I've had a look but can't see any obvious hose damage around the servo or hear any hissing. Has anyone had this issue before on this model or another? Would it be an engine out job or can it be repaired or replaced in situ? Thanks in advance

Hi there i've recently bought an Audi A4 estate and it's a great car - but sure you all know that already! I've just noticed that the brakes have started to lose the ability to stop the car if they are used several times in rapid succession - no problems at all if you just stand on them, the car stops immediately. Problem is when you use them constantly to slow down and then want to bring the car to a complete stop you really need to stand on them (pedal feels like the system needs bleeding). I took the car to KwikFit thinking it may just be air in the system (didn't really believe it could be as i'd not disturbed it so how could air get in!). When KwikFit fitter said car had to go to Audi to and suggested it may be related to the vacuum - any ideas/suggestions? obviously i'm reluctant to take it to Audi but i also need to have confidence the brakes are going to do the job!
