Yes, mistaken by the fluid on the carpet. That’s been transfer from a wet floor and panic in the moment! My wife drives the car mainly of late and it was when I got in it that the alarm bells rang so to speak. I’ve never known a hose union come loose in this way ever. It did get a cambelt and water pump done but that was back in August from a reputable garage, but then again….. It does have braided lines on it and steering movement left/right would push the banjo union loose if not fitted hard up to the stop flange face on the calliper. The N/S left right movement would serve to tighten it if that happened due to its orientation. The banjo in question was well away from the backstop face where it was originally fitted by me and the unscrewing motion would push it towards it. Malicious act is what I’m thinking as it’s looking like all of the engine undershield screws have been swapped out for old rotten ones. The ones on it were in very good condition for it’s age.

Found the culprit- hose to the front o/s calliper had come loose. 😳 Got it sorted with new banjo washers and bleeding the line but it’s getting a full system flush and pressure test. It is holding fluid and a brake pressure now.

Yes, I realise that. The problem is that it’s been soaking wet all day and it may well be fluid transfer from rain water on the floor too as there’s been that much lost. Wheels off tomorrow will see what’s going on there but yes the master cylinder needs checking too.

No remote reservoir that I know of but I think I’ve got my answer now. Looks like it’s actually the front o/s calliper or hose! It’s been chucking it down all day. I’ll be thankful if it is. Wheel off tomorrow when it drys out, there’s fluid all over because of the rain.

Looks like the brake master cylinder seals have gone the journey and dumped all of the fluid down the servo, then down the pedal piston. Quite scary if it had happened with the car on the move, thankfully it didn’t!

I should have mentioned it’s a dsg, so I’m not sure if that has the same clutch/brake fluid set up.

Hi folks, bit of an odd but scary one. Just went to start the motor up, 2019 vrs 4x4 tdi. Brake pedal hit the floor as though it wasn’t there, then on turning ignition on the dashboard warnings come on of low brake fluid etc. Usual checks round and the reservoir appears to be empty!! No visible fluid leaks around the outside of the car or engine bay but the carpet under the pedal box is wet with brake fluid 😳😳😳😳 Brake pedal just pumps as though there’s nothing there now. Could it be clutch related? Has anyone had anything like this?? Car drove fine until this, seems like pedal box failure. Yes I’ve been very lucky but something has gone on here…… Any help appreciated.

That solves that mystery Temple2019, makes sense that they go the journey all of the time! Bet they make a fortune using such a brittle material in a position like that. The old vrs ‘snot machine’ had the same problem with brittle vacuum hoses in silly positions. Told you this was a great forum 😎👍
