Since my A4 bj03 since I acquired him in 2006 the brake fluid was not changed I was looking for in the wake of a disc exchange for a cheap 1 liter container. Here I discovered this ATE product that only slightly more than the "standard" -Flüssigkeit, but was still significantly cheaper than in offline trading. The longer service life Like (2 years), in which I will in future really change the face of broth I've drained every 2 years. The fluid itself is actually thinner than a normal DOT4 and has a "flashy" color, which is very pleasant when moving, because it can be easily distinguished from the old. Whether it is better in their function I can not say where I assume that they can transmit braking forces slightly faster than a more viscous (especially in winter). I would recommend this product and then buy it now!
