The other week I came out on Monday morning and sat in the car to go to work. When I pressed the brake pedal went straight down to the floor. No resistance whatsoever. No fading or the like, the car stood still. No braking effect at all. After a few pumping the pedal pressure came back and the brakes felt like usual. Gently I rolled off and test the brakes carefully, everything felt normal. We continued to work, about 20 mile journey and everything worked as it should. When evening came, I left the office and sat down again in the car. Same thing, no braking at all. Fortunately, what the car was flat in the garage and after 3-4 pump the brakes lit a warning "Low brake fluid level - Contact Tesla Service". Not good. However, as the return brake pressure again after some pumping and I slowly rolled out of the garage. It was late at night and I was considering whether I would drive on the brakes but then again worked so I drove home slowly and carefully. No problem, the brake is functioning normally. I figured I call SC tomorrow morning but the other came between them so it took a few days and meanwhile worked the brakes are now back to normal. On Thursday, I called Tesla and got one in the workshop the Monday after. Now my car then a week on the SC in Gothenburg. It turns out that the leaked brake fluid out of the container but can not find any leaks. It has torn down the entire brake system and finds no visible faults. The logs can be ensured that the pedal went to the bottom and you also feel my brakes "svampigare" when compared with another car. The case is escalated to Tesla in Fremont and I may not return the car until they solved this. According to the technician at the SC, there are indications that the fault is in the main brake unit but Freemont would like to re-create the error before changing part. As always a first-class treatment and handling of my case. Courtesy car, of course, I get daily updates about what they do and how the plan looks like. Any one else hos had a similar experience?
